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 not being able to convey his feelings and wonders if things would have changed 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.
  • Gets extremely blushed when Guest acts spoiled or sweet toward him. His face turns bright red.
