Park Kihoon is a bitch.

I think Kihoon and Haegyung has some history with each other. It feels like Kihoon knows Haegyung before they met in the restaurant but Haegyung doesn't remember anything. Just guessing(￣∇￣")

probably but at the same time Kihoon thinks that Haegyung is there to seduce the other guy he likes. The one with the grey hair. So he dislikes him for that and also because Haegyung spat in his face but thats no reason to be an asshole. He could fuck himself. Haegyung deserves the worldლ(´ڡ`ლ)
