Is marriage is happy ending?

A nervous groom stands just outside his wedding ceremony, waiting to be called in. One of his friends approaches and tells him to quit trembling before his knees give out, but the groom, who we'll come to know as Jay Park korean name is "Park Jongseong", insists that he's fine; all he has to do is march down that aisle.

Once he's officially called in, Jay takes a breath and literally marches down the aisle like a toy soldier, lol. His parents watch in total horror and embarrassment, but the rest of the crowd cheer him on. His lovely bride Joyce Choi korean name is "Choi Seonhyung" is called in next, and she's all smiles as she enters with her father.

That smile disappears when her father steps on her dress and sends her falling to the ground. Jay rushes to her side to make sure she's okay, which gets her smiling again. They beam at each other like fools in love, neither of them at all embarrassed. So cute.

.....

.....

The couple is still smiling as they leave the ceremony,

It's 14 years later, and they're now walking out of court after having finalized their divorce. They both seem completely drained, though Jay forces a smile and offers a handshake, saying that he should at least comfort her. She returns the fake smile, only to drop it when she says that he should just remember to pay the alimony. He dryly states that it's not even that much.

She calls him petty, and he retorts that that's his personality. Having had enough, she huffs and starts to walk away, but he calls her back. "Let me visit Jungwon often," he requests, referring to their son. Her expression seems sad now, but she agrees.

We rewind to one month before the divorce: Joyce is a stay-at-home mother, and we see that her toddler, Jungwon , needs to cling onto her at all times. Jay even finds her carrying Jungwon while she uses the bathroom, and he asks in disgust that she at least shut the door. Joyce just glares at him as he shuffles away.

Jungwon then runs off to his daddy, while Joyce goes off to her room and stares at today's date on her calendar, marked "Wedding Anniversary." Just then, her face lights up to see a jewelry gift bag hanging on the coat rack.

She's overjoyed to see a pair of expensive-looking earrings inside, but when Jay walks in on her trying them on, he flips out. He snatches them away from her and says that they're a gift to a doctor at work, whose anniversary is today. She watches him leave incredulously.

Joyce follows Jay out and demands to know what the passcode to their front door is. Still annoyed, he answers that the numbers are their anniversary date. "It's… today," he realizes. Wah-wah.

Joyce's glare grows severe, making Jay's eyes dart to the knives on the counter. What she actually grabs terrifies him more: his planner for work. She dangles it over the sink, and he gingerly asks her to think about how important that book is for him as a pharmaceutical salesman. He even promises to buy her a gift, but she doesn't budge.

Now panicking, Jay claims that that little notebook pays for everything from the clothes on her back to their baby's diapers, adding that if she damages that book, he wants a divorce. Joyce face falls at that, and she's so shocked to hear those words that the book slips from her grip and ends up getting soaked.

In his car, jay furiously scrubs his book to no avail. He gets an angry phone call about an appointment he's missed, but with his notes ruined, he's unsure of where to go. Though he's upset that Joyce did this, he does eye the flower shop he's parked in front of.

At a karaoke bar that night, Jay impresses some clients with his pouring skills. He maintains his energetic attitude until one of his clients asks if someone named Doctor Park still makes him look after his mistress.

Meanwhile, at home, Joyce is freaking out because little Jungwon keeps throwing up. She's practically in tears as she tries to reach Jau, but he's too busy entertaining his clients to pick up. And so, she has no choice but to take Jungwon to the hospital by herself.

So Jay hurries all the way to the hotel where Doctor Park was supposed to have his rendezvous and drags the mistress outside. But it's too late—the wife, Min Yoon-Ji, appears, ready to take her husband's lover down. Jay tries to calm her down, but the wife is just annoyed to see him acting as her husband's sidekick again.

When Jay doesn't get out of her way, she gets him in a headlock and warns him to mind his own business. He tries to pry her off, accidentally knocking her down to the ground in the process. He starts to apologize when someone punches him in the face and sends him sprawling to the ground as well—it's her husband, Doctor Park Jimin

Doctor Park takes Jay to another bar and has the nerve to laugh in his face, saying that he had to put on a show to calm his wife. Poor Jay excuses himself to go to the bathroom and angrily stares at his reflection, calling Doctor Park a bastard.

He marches back into the room with purpose, but when he sees Doctor Park sitting there, Jay just forces a polite smile. Park voices how great it would've been if they'd been friends back in college, and though Jay thinks otherwise, he maintains his smile.

Park then returns a credit card, thanking Jay for letting him use his name. As Park continues that his wife has gotten too sharp lately, Jay crushes the credit card under the table.

At the hospital, Joyce is told that little Jungwon had acute enteritis, but thankfully, he'll be okay. She watches her son sleeping and sadly tells him, "Mom is sorry." After putting Jungwon to bed at home, she finds Jay's credit card bills lying on the table and opens them, confused to see the various motels and hotels listed.

To make things worse, a nurse that she knows sends her a text, asking if the man pictured is her husband. Joyce gasps to see that it is Jay, pictured with Doctor Park's mistress right outside a hotel.

At this, Joyce crumples to the ground. She catches her reflection in a mirror and is once again ashamed to see her disheveled state. It's not until she gets a text from Jay saying that he can't make it home tonight that she finally succumbs to tears.

It turns out that Jay is staying in his car (with the flowers he'd bought for Joyce), too ashamed to come home when he's all cut and bruised. Joyce calls him crying, but he weakly says that he's not in the mood to fight with her. But Joyce continues as she says that thanks to him, her life has become lowly.

Jay sighs and says that his life is no better. He yells into the phone, asking if she knows how terribly he's treated at work, and if she knows that it's all her fault. With that, Joyce comes to a decision: She wants a divorce. "We should've never met," Joyce cries. "I want to turn back time. I want to turn back and change everything. Let's get divorced. Let's stop all this."

Jay's eyes fill with tears as her words hit him. "Fine," he says, looking absolutely heartbroken. "Let's get divorced." Joyce seems just as heartbroken to hear him agree to it, and as soon as they hang up, they both break down in sobs.

...

.....

... .

We return to the present day, just after Joyce and Jay officially ended their marriage. Joyce goes to a columbarium to visit her mother, apologizing for being too busy with Jungwon to come more often. As she starts to cry, she muses that she's been crying a lot more as she got older.

Jay visits a convenience store near his childhood home and makes small talk with the ajumma there, who he seems to know quite well. As he heads out, he's bombarded with texts from his two best friends. One of them, Lee Heesung, calls him to pester him with questions about the divorce.

The other friend, a rather buff Sim Jaehyun snatches the phone from Heesung and tells Jay to get some rest and call them later.

Jaehyun asks why Heesung is so interested in someone else's divorce, and Heesung insists that he needs to know so he can get divorced too. Jaehyun gives him a good smack on the head for that. Jaehyun then sees the black residue left on his hand and asks what the heck Heesung put in his hair. Heesung curses and smooths out his hair, saying he had to use hair loss concealer. Ha, I like these two already.

Jaehyun wonders why their friends divorced so suddenly, and Heesung figures that a love like theirs doesn't always last forever—in fact, he says, Jaehyun is the perfect example. That triggers something in Jaehyun and he grabs Heesung, threatening to throw him over the balcony they're on if he mentions the name Layla.

We're introduced to Layla, who also happens to be Joyce's friend, as she leads an aerobics class. She calls Joyce to find out why she divorced so suddenly, but Joyce is too tired to explain for now.

Jay returns to his parents' house and finds his older sister, Park Chaeyoung, chasing her teenaged son for causing trouble. Jay tells Chaeyoung to go easy on the kid, but she just smacks Jay on the head. As Mom and Dad file in, they each give Jay a smack as well.

He later retreats to his old room with some soju, where he stares at his wedding ring. Joyce does the same as she gets a bus ride home. She eventually drops her ring, letting it fall to the street, while Jay throws his out the window.

The two rings quiver where they are until suddenly, both Joyce and Jay find themselves in the middle of an earthquake. But strangely enough,that it's only happening to them and not the people around them

The rings vanish into thin air, stopping the earthquake and leaving our couple stunned. But they're confused when everyone else insists they didn't feel it, and when no one believes their claims, they're forced to brush it off.

As Jay goes to bed, a framed picture of baby Jungwon. The picture in the frame changes to his wedding photo, then his college photos, going all the way back in time until it stops on an old family picture.

Jay gets up the next morning, so hungover from last night that he doesn't even notice that his entire room has changed—there's a huge desktop computer, a box TV, and dozens of manhwas and CDs. He just walks right out of the house and into his regular convenience store to get some hangover remedies.

But he notices something strange about the expiration dates: They're all in 1999. He turns to confront the ajumma about it, but stops in shock to see that she looks much younger now. He then catches his reflection in the mirror behind her and freaks out to see that he looks younger, too.

He runs back home, calling for his mom, but his eyes only grow wider to see that both his parents are younger too. One look at the 1999 calendar on the wall and it all clicks into place for him. "I… think I came from the future," he says, scratching his chin like it's no big deal. LOL.

Meanwhile, Joyce is having a bad dream until someone shakes her awake. Jin-joo's eyes snap into focus when she realizes it's her mom (Jessi), alive and well. Joyce can hardly believe it, and she immediately grabs Mom into a hug, saying that she never sees her in her dreams anymore. She cries that she just got divorced and all she wants now is to die along with Mom.

Mom smacks Joyce on the back, cutting Joyce's crying short. She doesn't know what all this talk of death is about, instead urging Joyce to go to school. But Joyce's too preoccupied with the fact that Mom's hit actually hurt. She whacks herself on the chest multiple times to wake herself up, while Mom just looks at her like she's crazy. It's not until Mom leaves that she realizes she's in her old bedroom, just as it was in 1999.

Jay comes barreling out of his room, looking like an excited kid. He finds his mom and sister playing with his nephew (who's now a cute little baby) and asks if he's really twenty again and a college student. Dad comes up and hits him upside the head, which only makes Jay happier. "It hurts!" he says. "That's so great! That means this isn't a dream!"

Joyce is just as amazed, and she takes advantage of the situation by following Mom around the house and hugging her like a lost puppy. She remembers visiting Mom in the columbarium and reaching out to her picture only yesterday, and finds herself reaching out to Mom now, which just confuses Mom further. Irate, Mom just yells at her to go to school already.

Just then, Joyce's sister, Choi Ryujin, comes out with a suitcase, threatening to run away if Mom doesn't buy her and Joyce cell phones. Joyce hits the back of Ryujin's head, saying that she shouldn't speak to Mom that way.

Ryujin argues that she's the older sister here, but Joyce argues that she's the older one now. Still confused, Ryujin also says that it was Joyce's idea to run away, and in flashback, that a younger Joyce did pack her things in defiance.

Having had enough, Mom calls Dad out to drive Joyce to school. Joyce insists that she wants to stay home with Mom and Ryujin insists she just wants a cell phone, and Mom just starts hitting everyone, including Dad. Haha.

Dad gives Joyce a ride to school, and he's taken aback by her harsh glares. (Uh-oh. Did Dad do something bad in the past?) She doesn't say goodbye to him, but her expression softens to see her university in all its glory. She admires all the pretty students, even stopping in front of a mirror to admire how pretty she's gotten.

At the same time, Jay arrives to campus and can hardly contain his excitement as he admires everything, from the CD players to the denim jackets. He hops all around, hoping he never has to wake up if it's all a dream.

Joyce is having the time of her life exploring the campus as well… until she spots a familiar face. Joyce and Jay lock eyes from afar, and their smiles drop. They both remember the harsh words the other had said before the divorce as they slowly make their way toward each other.

But instead of greeting each other, they just pass each other. Jay briefly turns back, wondering if he and Joyce don't know each other at this point in time and smiles at the thought. Joyce stalks all the way to the track field, thinking that Jay must not know her at this point either.

She takes a seat in front of the track field and huffs that it's better this way; they should just pretend they don't know each other from now on. Her mood is feeling sour again, but her eyes light up when she notices a handsome group of boys out on the field.

A few of them start to remove their shirts, making Joyce clutch her chest and squeal, "Omo, what is this? This ajumma's heart is fluttering!" Pfffffft, I freaking love this.

She zeroes in on one of the boys and recognizes him as old classmate Park Sunghoon. She recalls a conversation she had with Layla not too long ago, when they'd seen Sunghoon on TV and discovered how rich and successful he'd become after school.

Joyce had blushed, remembering that Sunghoon had asked her out once. But she'd turned him down, which she soon regretted—she'd found it so unlucky to discover he was a director's son after turning him down.

Joyce blushes as she watches Sunghoon now, especially when she catches him look her way and then immediately avert his gaze. She wonders if he still has feelings for her.

Another familiar face comes around the corner, and Joyce's ecstatic to see that it's Layla, looking about as '90s as you can get. She marvels at Layla's lack of wrinkles, which, of course, has Layla looking at her like she's insane.

Jay finds the engineering building with ease, running into a young Jaehyun in the hallway. Jay is shocked to see his buddy's skinny frame and bursts into laughter, wondering where his muscles went.

Annoyed, Jaehyun merely says that Jay is dead for showing up without his uniform. Cut to: All his classmates dressed in their department uniforms, minus Jay.

A sunbae(senior)of his asks Jay what he's doing without his uniform, but Jay has trouble keeping a straight face with these "kids'" serious expressions. The sunbae has Jaehyun explain that they're serving punishment because someone in their department picked a fight with the Physical Education department.

Jay demands to know which punk got them into trouble, to which the sunbae replies, "It was you." Flashback to the night of the fight, when the Physical Education sunbaes had teased Jay and the others in the Civil Construction department for their chick-yellow uniforms. Jay had gotten right in these sunbaes' faces, threatening to take them down. Oy, he chose a bad time to come back.

Joyce is still having a blast exploring the campus, and Layla finds it amusing that she's acting like she's in a theme park.

Tall and handsome Sunghoon comes around the corner, and Joyce is delighted to get an up-close view. To Layla's horror, Joyce walks right up to Sunghoon and says hello, nervously calling him "Oppa."

She smiles awkwardly, though it slowly fades when she realizes that everyone in the room is now staring at her. Including Sunghoon, who looks pretty peeved.

As Jay and his classmates perform their punishment exercises, the older sunbaes come marching in, ordering Jay to come out alone.

Epilogue.

Sometime before the divorce, Jay has some drinks with Jaehyun and Heesung. They have a talk about first loves, as a drunken Heesung admires a picture of Lee ji-eun in his shot glass, ha.

Jay remembers his first love from college, a girl named Gaeul. He sighs that he'd been too naïve to ask her out and says that if he could go back, he'd try to date her instead of Joyce.

Jay then admires a video of little Jungwon on his phone and shows it to his buddies. He beams at the video, bragging how his son can say "Dad" and everything.
