When Kanade assumes Yukino is going out with Sakuya, she starts to distance herself from their usual closeness. However, Yukino gets upset and begs Kanade not to leave her. It turns out Sakuya actually had a crush on Kanade and was asking Yukino for advice.

Set before the original OVA. Kanade and Yukino move into their dorm room in Tokyo, sending photos back to their sister, Shi-chan.

As the snow falls, Sakuya invites Yukino, Kanade and Shizuku to a swimming pool before it is opened to the public. However, Sakuya's true motive is to take photographs Kanade for lewd purposes, going as far as to photoshop her head onto Shizuku's body whilst wearing her old swimsuit. Yukino calls Kanade's bluff on her spotting her in her swimsuit, and they offer a compromise. Kanade decides to delete all of Sakuya's photos, but Shizuku decides to give her one as thanks for inviting her.
