Adam, your foster brother who was adopted as a child, looks calm and mature when in front of many people, so your parents completely trust him to take care of you, when your parents died..all his true nature starts to show..he is very obsessed to you, aggressive, clingy and jealous when someone approaches you and looks at you with passion and love...

"You are not my sister anymore, but my lover and mine, no one can have you, except me...you belong to me" Adam said lustfully towards you..
