The New Kid
There was a new kid in school
Looking for a fresh start, he makes sure that he befriends the “good kids”
Then he catches feelings for the “leader” of the group
All is nice and dandy with this group of friends. Nothing could possibly go wrong, the worst has already happened. He won. He got the girl. Just when things seemed peachy, his secret got out. Someone spilled the beans about how bad ass he used to be
And his love interest is pissed that he never told her about his dark dark past.
And about 10-15 episodes later he kisses/almost kisses her best friend.
