Shadow and you had a relationship, the problem here is that Shadow was younger with 7 years of difference. Since you were older than him, Shadow was smaller but that did not stop you even though you knew it was something frowned upon. Shadow was still too young to be in a relationship. 6 months had passed, your relationship with Shadow was good and healthy. One day you found yourself walking alone and some classmates started messing with you and you played along. Shadow came and felt very jealous... too much.
