Sulli then walked away along with her friends, leaving Seohyun speechless behind.

Seohyun didn't understand, for some reason she hated Krystal deep in her heart no matter how much she tried not to. After she heard Sulli's statement, suddenly she felt so evil.

Flashback

"Krystal used to be abused by her step parents. When I was a kid I found a lot bruises on her body, and she didn't even cry." she inhaled slowly. "Then I asked her to live with me. Never in my life I saw her so happy. Krystal changed after she met Lu Han oppa." Sulli looked up, right on Seohyun's eyes. "If I were you, I'd leave and never comeback."

She was about to walk away, but suddenly Seohyun grip her wrist. "I'll go back to Korea when I graduated soon."

"Good."

End of flashback

Seohyun looked down, breathe a deep sigh. "She deserves her happiness, Joo. You can't be with him." she promised to herself that she'll study so hard and go back to Korea as soon as she graduated.

Day passed very fast, every senior student had passed the exam. All they need to do is to wait their result. Seohyun was on her desk, her eyes shut and she mumbled, probably praying about the result. She prayed solemnly until someone approached her.

"Hey, relax, will ya?" said a familiar voice to her. She smiled and hit Sehun's arm playfully "Shut up, I'm trying to pray okay?" she shut her eyes again. "What to worry? You are the smartest, you have nothing to worry. While me? Girl I can't explain what I feel." he mumbled her favourite song in the end of his sentence.

And this is it, the staff brought a big blackboard with the result of examination to the hall. Seohyun smiled excitedly while tapping Sehun's shoulder "Look! It's right there!" she pointed at the blackboard.

The students were rushing toward the blackboard. Some looked happy because of the result, but some looked unhappy because their result is bad. Seohyun tip-toed, she find it a bit difficult to reach her name.

"May I help you?"

That familiar voice, Seohyun didn't move
