Synopsis
Raiha takes Futaro out shopping and invites Itsuki and Yotsuba to join them. Raiha mentions Rena, calling her Futaro’s "first love". On the bus, Yotsuba learns that Miku made lunch for Futaro. The girls decide to play a card game. As a penalty, the losers must obey the winner. Once they arrive, the sisters follow behind Futaro and his friends up the mountain, and when the path splits, Yotsuba, having won the card game, orders Itsuki, Ichika, and Nino to go up one path, while she and Miku go up the other. Ichika, determined to win Futaro's love at any cost, sneaks away to make it to the top first while in her Miku disguise to fool Futaro. However, both Yotsuba and Miku arrive shortly after, and discover what she was trying to do. Yotsuba chastises Ichika for getting in the way of Miku's confession. Futaro overhears this and Miku sprints down the mountain, crying. Later, Futaro admits to Yotsuba that he was already aware of Miku’s feelings. The following day, Itsuki tries to get closer to Futaro. Nino confronts Miku, who has been depressed in her room by herself. Nino tells Miku that she will use this opportunity to make Futaro hers if Miku gives up, but encourages her not to do so if she truly loves him. Itsuki tells Yotsuba to tell Futaro the truth, that Yotsuba is "Rena", the girl from Futaro's picture.
