The aftermath of the ferry incident signals a clear shift in Kazuya’s feelings. Meanwhile, there’s a conspiracy brewing at the hot springs inn he and his family decide to visit.

Christmas rolls around with Kazuya not having met Chizuru for ages, and he sees something he never wanted to see.

When Nagomi hears that Chizuru's birthday has already passed, she decides to throw a combined party for both her and Kazuya, and she refuses to take no for an answer!

Kazuya can barely process Ruka's actions when Nagomi decides to drop another bomb on the party.

Kazuya has hardly begun to process the fallout from his birthday when he gets asked to go on another practice date with Sumi, this time with her taking the lead!
