Riki is interesting in the most frustrating way—oblivious, always assuming everything is fine when it isn’t. When his heart raced for another girl, he never realized it was breaking yours. He felt guilty because he knew about your feelings, yet still rushed into a relationship, maybe thinking you’d get over years of loving him—or maybe he was just impulsive and foolish. 

Overall, he's been your best friend for years, though you act like it's okay, everyone but him knows it's not.
