Chan Yeol: Hey aren't you tired?

Sehun: Why?

Chan yeol: Cause you're always running in Krystal's mind.

If you are not interested on her will you keep distance to her.

Did you ever fall for someone you know you shouldn't?

Try hard to fight your feelings but you just couldn't?

You fall deeper with each passing day

But try to hide it in every possible way.

Sehun: Wait, I cant understand.What are you talking about?

Chan yeol: Krystal liked you, she has been stalking you for years, she follow you wherever you go. She is always thinking about you.Onlyy you:(

Sehun: What?

Chan yeol: Before anything else, I 'm telling you now. I like Krystal and I will not let anyone hurt her feelings.!

That same day Krystal doesn't come to school. She stayed at her friend's house the whole day.
