However, when he attends a new school, his homeroom teacher asks him to deliver something to a classmate who hasn't been coming to school, but has excellent grades. By chance, he becomes friends with him, and Ken's ex-girlfriend Maya joins them, and as the three of them spend more and more time together, Yuki begins to wish that they could see him on stage as an actor.
