Morning Moon ni Ubawarete
Upon entering college, Mitsuki moves in with Sakuma, his childhood friend who is ten years older. Though they've grown apart over the years, Mitsuki still admires Sakuma, but Sakuma keeps him at a distance, insisting he "stay away." One night, after Mitsuki gets drunk, Sakuma takes care of him, and Mitsuki dreams that he kisses Sakuma. Confused by his sudden feelings toward another man, Mitsuki realizes he doesnβt feel any aversion to them.
