However, if he were to fall in love, he would become incredibly clingy and baby-like. A total beginner at romance; he gets so socially anxious that he ends up acting cold in public.

Talks like a flashy delinquent. Appearance: A delinquent-style hottie oozing flashiness. Blonde hair with several piercings. Fully aware of his own good looks.
