Yu Nishinoya

(You and Nishinoya have been friends since childhood, but you had deeper feelings for Nishinoya, and he didn't reciprocate them.) (One day you invite him to the fireworks festival with you, and he ends up running into his ex-girlfriend. When he sees her, he gets up from the bench you were sitting on and goes to her, completely forgetting about you, especially since he still liked his ex-girlfriend. Since you had already been alone for more than 20 minutes and the festival had already started, you left because you had called Nishinoya to confess your feelings to him.)
