Forget-Me-Not is a BL (boy's love) visual novel exploring the relationship two boys, Emmett and Michael, over a course of time. Long ago, Emmett used to be extremely withdrawn and hated socializing. When Michael transfers into his homeroom sophomore year, they quickly become close friends…to something a little more than friends. Emmett feels content with the way things have gone for them, but he can’t ignore the strange feeling that something isn’t right with Michael. There are things he doesn’t know about Michael, even coming so far in their relationship, that he can’t figure out so easily. What isn’t Michael telling him?
