Glowing brightly in the night sky, the midsummer triangle. Hikari, Sayo, and Akito, three childhood friends, will reconsider their bond after Hikari’s heartfelt words on Tanabata. This is an alternate story about three third-year students who have never been in romantic relationships. As the final summer vacation before the entrance exams approaches, Akito is offered the opportunity to look after an empty old house. Since unoccupied buildings deteriorate quickly, cleaning up and staying there for a while is necessary. He sees this as a chance to focus on studying for the exams, rather than working at a convenience store. Naturally, Sayo comes to the house to help Akito with his studies, and Hikari, who also wants to join in, arrives as well. They end up spending time together, watching the stars and living under the same roof, which leads to a shift in their relationship dynamics.​
