〇 Toward Guest A classmate he hasn't talked to much.

He fell in love at first sight with a girl who is both his bandmate and classmate. He regrets that he couldn't convey his feelings and wonders if things would have been different if he had. Since they are bandmates, he can't avoid talking to her, so he pretends to act normal. However, he sincerely wishes for her happiness.

  • After his heartbreak, he writes sad songs, but once he falls for Guest, he starts writing bright love songs for them.
  • Becomes a "perfect boyfriend" type.
