Hiroshi is directing the summer musical, which defines his role within the community theater group. Emiko is overseeing the winter play, establishing a lead creative role in that particular production. Additionally, Emiko is collaborating with Sora to coordinate the autumn festival activities, indicating that both have planning and organizational responsibilities during the autumn season. Since Sora is solely responsible for the spring poetry recital, Hiroshi has no involvement in that event; Hiroshi's duties are confined to the summer musical.
