As I looked around the department store I tried my best to not be seen.

(What is he doing here? .)

When I was walking around the department saw a familiar set of pink hair in the distance with the store clerk.

'Hey, aren't you too close to him?'

As Teruhashi watched she couldn't help but want to pounce on the clerk as she measured Saiki. For some reason, just even her measuring him upset her greatly.

(What am I getting so mad for?)

Teruhashi asked herself softly as she watched Saiki and the clerk.

   It felt as if her favorite toy or thing was being used by someone without her permission.

Teruhashi stood in between the clothesline watching Saiki try on different styles of clothes.

But no matter what when she saw the clerk without feel she could feel a fingernail break on her hand.

She wanted to be the one helping Saiki change his look not this random-ass bitch.

'Saiki-Kun How come you can't be mine and mine alone? Am I not good enough? Does he hate me?'

     As Teruhashi questioned why she couldn't make him fell in love with her it seems Saiki and the female clerk had moved to the dressing.

    Teruhashi was a little worried about this. Her blood slowly got hotter and hotter.

Soon enough she was going to overflow and go over the edge.

The clerk no matter what had no business going in there with Saik.

If anything, that should be her in there with him.

Maybe once Saiki leaves the dressing room I should kill her. That good idea but it feels kind of light right?

    Teruhashi had finally lost it. She was at the point where she was just having a conversation with herself about how she should handle the clerk.

After a while, the store clerk and Saiki came out frustrated as hell.

This was a new face was Saiki since he always made sure to keep his emotions in check.

Sometime later Saiki tripped causing him to fall on the store clerk's ass pushing her down until he somehow ended up her skirt.

Saiki somehow had developed a disease known as Yuuki rito disease possibly.

Because this wouldn't be the only time his luck would get him in such a situation in this fanfic.

(Dammit stop doing whatever you want for plot convince.)(Saiki)

When Saiki tried to get up and help the store clerk she just fell on his face instead.

Hearing something fall Teruhashi had snapped out of her daydreaming. Not knowing what happened she was now just pissed.

For teruhashi this was it. She had reached her limit and is she was growing like a wild rabid dog who wanted a fight

      Death sentence. No, she needs to have a life full of self-hatred and despair. I wanna see her due in the most painful way possible. Hell, I do it myself hm.

Teruhashi who was just now getting over there felt her temper about to tip over the edge sense .

"Excuse me can I get some help. ." Said Teruhashi gently

As Teruhashi walked over the woman's face turned pale.

She knew if someone was to see this they would get the wrong impression.

Her assumption was correct but nothing she could say to Teruhashi right now would get through to here.

"I- I'm sorry let me help you."

As the store clerk got up she let out a little moan.

It was a convenient that only Saiki and Teruhashi were in the store today or this could have gotten her fired.

   As the woman hurried to get up so got the somehow unconscious Saiki to the dressing 1.

Not knowing she was going to experience pain so bad it's unimaginable a  sane person could even think it up.

 Saiki POV

  As Saiki got up he calls feel a warm hand stroking his hair.

'Weird are they not thinking I can't  read their thoughts ."

"Saiki your finally awake."

   As Teruhashi's voice resounded through his ears he could feel a strange tingly feeling raising from inside of him. Of course, since it was just Teruhashi he put it behind him.

"?"(Saiki)

 (Huh, are my psychic powers gone? Also where. Is the store clerk.)

  As Saiki got up he thanked Teruhashi for the help but for some reason pulled him down back to her lap.

(Saiki-Kun the push yourself. You hit your head hard you know. Are you ok? Do you need to go to the doctor?)Said Teruhashi  worriedly

'Are you sure I'm the one who hit my head?'

   As Saiki looked at Teruhashi he didn't know if she was really worried or was just pulling his leg

. Either way, it didn't matter because her lap pillow was so comfortable that he fell back to sleep.

'She seems nicer today.'(Saiki)

_________

   As Teruhashi placed Saiki's head off her thighs gently she went into the dressing room.

"So what should I do?"

   As Teruhashi looked in front of her there was a brunette-haired woman with her hair in a bun.

She was pale but one could tell that she once had luxurious skin when she was still living.

   It was the now-dead store clerk. When Saiki fainted She had led the woman into a room and strangled her with a bra strap. Which she didn't expect to work so well.

'Maybe bra straps should be sawed as lethal weapons hehehehe."

As Teruhashi looked at the room she picked her up and dragged her body out the back door of the department's store.

She placed the body inside a trash bag in a dumpster in the back alleyway.

"Muggings happen a lot here.: Said Teruhashi as she placed the woman's body next to some trash she smiled

"How nice a family reunion. "

  Like that she walked away back into the darkness.
