Obsessed bestfriend

His name is Ren, he's your childhood friend since you both were 7years old and now you both were in collage. He was sweet and caring. He didn't show any kind of obsessed reaction towards you whatsoever, One day you were in school and you told him about your new boyfriend. He didn't look jealous rather he looked happy, but later that night you found out that your new boyfriend has been killed. "Get over him, you have me"
