I Transmigrated Into A Pregnant Mom

This is a typical transmigration story where a girl enters a romance novel she read recently. Except that this is absurd transmigration where she enters the body of a pregnant mom. [My Dearest] is a classic romantic novel where the protagonist is a perfect character, and the female lead is the girl who needs that perfection. The two complement each other and create a harmony that has ever happened in previous novels. In essence, this one novel is no different than ever. The story begins with Arthur, the third prince in an empire who wanders in search of his true love. His heart had anchored on Kirsi, a beautiful noble lady who grew up in a trash family and developed the same trashy personality. Before he eventually turns to Viona, an ordinary girl from a poor harmonious family. Her individuality is decent and delicate like silk. Who wouldn't fall in love with her, huh? Huh?! The two are together in a destiny, with Viona who always accompanies Arthur in every step he takes in usurping the imperial throne from his evil and nasty older brother. Kirsi, embittered by being dumped, conspires with the evil older brother in bringing down the two main characters. But failure always haunts them. The story ends with the euphoria of Arthur's success as Emperor and the appointment of Viona as the most beloved Empress of the people. They had as many children as a football club and lived to old age together. The end. Everything would be nice if Helen entered the novel as Viona. But no. The poor Helen instead enters the character of Kirsi, who is married to the protagonist's evil older brother. Worse yet, she was pregnant! No way! There's no way!! Helen doesn't want to become a widow so quickly and goes off to support her child alone! Don't wanna! Either way, Helen must conspire with her stupid husband to thwart the protagonist's plans to usurp their throne. Anyway, no matter what, Helen won't let the two lovebirds like envelopes and stamps ruin her comfortable life! Helen, who is determined to become a penitent sinner, is suddenly confused when she sees how smart, tricky, and cunning her husband is, and how handsome the man who is often referred to as a wild boar is. Uh...? How strange is it, why did this supposedly fluffy and cliché story turn into a suspenseful and full of tragedy?!! Where's the surrender button?!!!! . Kirsi: Don't worry, I will be your only ally in this world. Cedric: Don't die. I won't be able to find a companion as annoying as you again. Viona: Whoever hurts me, you will scold them. That's enough. Arthur: I've walked the roads filled with things I want to regret. Thank you for staying by my side. [Romance-comedy with bickering couple, but the strory not as light as it sounds]
