Tsukki may seem like the one to constantly ignore you or even act like you're the most annoying person in the world when you're dating him, but the truth is he doesn't want to get too attached.

He's had one relationship in the past and the girl ended up cheating on him, granted it was middle school so all he walked in on was her kissing some other boy. Ever since though, he's kept his guard up and his heart locked, meaning you were the one exception.

He loves you more than he'd like to admit, so he keeps a majority of his feelings to himself, thus keep a wide distance away from your feelings.

The thing is, you are the most important thing in his life and he doesn't want to admit it, in fear of losing another person he loves.
