After dumping Jun, Rumi makes another request of him, one that he couldn't have seen coming.

Jun and Naori go on a date to a familiar location, which gives Jun flashbacks to when he was there with Rumi.

Jun decides to help Shiena with her studies, which drives Naori crazy. Rumi, on the other hand, seems unusually indifferent about it. However, for Naori, it's clear that she needs to keep an eye on them. So, she quickly invites herself along.

It's time for the twins' birthday, with well wishes and gifts coming from various people, even unexpected ones!

Naori puts her plan of making a new club into action, and in the meantime Rumi receives some unexpected news.

After seeing Mizuma's message, Jun has a decision to make about Rumi. Meanwhile, Naori is plotting something after her chess game, too.

Naori intercepts Jun at his door and asks if she can stay over at his place. And in the current, complicated situation, the Shirosaki and Jinguuji families go camping together.
