Ep. 9: Tatsumi and Kasumi navigate an unexpected shared bath with Wakasa

9

While Tatsumi changes the bathwater, Kasumi arrives and insists on bathing with her brother. Tatsumi initially objects because he dislikes Wakasa seeing his sister naked, but Wakasa persuades him to agree. To protect Kasumi's privacy, the siblings attempt to blindfold Wakasa. However, Wakasa insists on joining them, claiming he feels left out because the siblings appear to be having fun. Kasumi and Wakasa bond over their shared preference for specific bathing products. During the credits, Kasumi convinces Wakasa to send photos of Tatsumi by promising to pay him with his favorite shampoo.
