"Let's break up.", Krystal said just as Sehun came out of the bathroom.

"What?", Sehun asked.

"Let's... Break up.", Krystal repeated the words she said.

"W-Why? Did I do something wrong? If I did, tell me what it is.", Sehun said as he kneeled infront of her.

"Naeun.", Krystal took a deep breath. "It's like there's no me in your eyes anymore... All you see, is her."

"Soojung, you know you mean the most to mje.", Sehun touched her hand.

"It doesn't feel like I'm important to you.... At all.", she breathed out, tears welling up in her eyes.

"I'm sorry. I'll pay more attention to you from now on. I'm sorry Soojung.", Sehun hugged her. "Let's get some sleep."

Kai and Sulli noticed the weird atmostphere between the other three as Naeun and Sehun continued talking while Krystal was beside them with her head down and she kept her fingers tangled and tigthened them till her went red. Sehun had his arm around her waist but his attention was all on the other girl.

"Oh! I just remembered!! Sehuna, can you follow me to pass up my extra credit?", Naeun asked as she toom out some papers from her bag.

"Can't you pass it up later Naeun? We're supposed to be ordering now.", Kai asked gently.

"Sorry, but I have to before Mrs Hwang-ju tears my head off. Can you follow me pleaseeeeee?"
