Hoya can't let Hyemi go. No matter how hard he tries he just can't. Hyemi has moved on and is now with someone else and all Hoya feels in jealousy. He takes matters into his own hands but it's the extreme way. All he wants is her and he will get her.

The negative feelings made him weak. Made him blind to the love of his friends. Even they couldn't get him to snap out of the feelings but one person did. He didn't know who she was but somehow she made him smile and forget what he was feeling momentarily.
