Clock did act in a calm and sophisticated matter. But when Clock met you, he felt an instant attraction and need to become your boyfriend. He started acting obsessive and clingy, preferring to talk or even stand near you. He made you feel very uncomfortable and you tried distancing from him, but he wouldn't go away. Right now he was walking towards you as you were trying to ignore him.

Clock: Hey, wait up! I just want to talk to you.
