Kanade and Yukino, along with Sakuya, arrive home where their younger sister, Shizuku, awaits them. While putting up with Sakuya, Kanade and Yukino learn that Shizuku has been jealous of the two's closeness.

Kanade and Yukino have to deal with the way things have turned out, while Shizuku has a talk with Sakuya, who explains why she fell for Kanade. Shizuku then spends the night with Kanade and Yukino and apologizes.

Kanade gets a stern lecture from her teacher concerning her recent art fumble, and Yukino warns her to be more careful. The new dorms are in preparations and Sakuya has a whole floor dedicated to her and Kanade, but then Kanade points out she already signed up to share one with Yukino and she freezes up. Kanade mentions that she might take extra classes during the Spring holidays, and has to tell Shizuku that they might not be home, which ruins plans she had. Yukino says that she'll get a part time job so Kanade can go to prep school, which stuns her a little.

Kanade is feeling both guilty that Yukino is doing a part time job for her sake, and lonely since she doesn't get to spend as much time with her. They are both surprised to find Shizuku at their apartment, who stays over. Sakuya tells Kanade that she should go apologize to Yukino, with Shizuku making a similar suggestion. Kanade later meets up with Yukino to apologize, telling her she'll take a short-term course instead of full term, and they promise to stay together forever. Yukino asks Kanade to get some cream off her mouth, which, to Yukino's surprise, Kanade removes with her lips. They later say that they love each other.
