After waking up, Riki learns from Yuiko that she was taking care of him while he was asleep and cannot shake the suspicion that the whole situation has happened with them in the past. Some time later, Kyousuke and the other boys point out that Riki is behaving strangely since his last encounter with Yuiko. Believing that he has fallen in love with her, they decide to have him lure the girls to the school building as they prepare a fireworks show for them, with instructions to find a way to get alone with Yuiko to set up the mood for his "confession". Wondering if he is actually in love with someone, Riki does as they say, but ends up alone with Yuiko by accident when the fireworks begin. The following day, Riki realizes that the same events of the previous day are being repeated as the date is also the same, June 20.
