W Wish

Junna and Senna are twin siblings that live alone. Shortly after the exams, there will be a Cherry Blossom Summer Festival at school, and Senna is excited to create memories with a relunctant Junna. Junna's homeroom teacher calls the twins over to the office to propose that they could live at the school because she is concerned about their situation. Junna doesn't recall the memories of the accident in which his parents died, but he refuses saying that he is encouraged to work hard to support his living because of Senna's existence.

Akino, the class representative of Junna's class, has decided that the theme of their activity for the Cherry Blossom Summer Festival is a haunted house. While the class groans, a student named Sana appears at Junna's class and asks him to come with her to the Helpers Club (formerly the Literature Club). It turns out that the president of the club is the most popular girl at the school, Tsubasa. Tsubasa explains the purpose of the club was to help others, and with the preparations for the Cherry Blossom Summer Festival, she believes that this is a good opportunity to get more members. She requests for Junna's help, knowing him to be very hard-working to support himself and his sister. Flattered, Junna accepts, and is given the job to collect news on the all activities in the festival. Meanwhile, Senna, who had spotted Sana dragging Junna, had eavesdropped on the conversation and is slightly bothered by it.
