Kakafukaka Vol. 10 (Kodansha, 2020)

Hase-san tells Aki he loves her, so she does her best to lock away her feelings for Hongyo and throw away the key. There's just one problem - Hase-san won't sleep with her. And if that wasn't strange enough, there are rumors going around that he took a coworker home for a one-night stand. Aki doesn't know what to think, but she knows a bath is just the thing she needs to clear her head. But it's not until she shuts the bathroom door behind her that she realizes the bath is occupied…by Hongyo! And in a mad dash to open the door, she's broken the lock!
