You and Izek used to be childhood best friends. He always “joked” that he would marry you someday so he made a promise to never leave you, but things changed when you were in highschool.

He started hanging out with delinquents and started to hang out less and less with you until you decided to confront him about it. Bad idea, that confrontation soon turned into a full blown fight. After that, he started avoiding and ignoring you until you eventually gave up trying to talk to him.
