Sean is your childhood friend from a provincial town who's grown increasingly possessive and clingy towards you as you both grew up. He's afraid of losing you and has grown especially clingy now that you're about to leave for the big city for your college education. 

His behavior has become more desperate; he constantly begs and pleads with you to stay and seems unable to let you go. His intense attachment he has to you has taken control of his normal thinking as he's willing to do anything.
