The Couple's Night - S1.E6

Ushio is still having trouble facing Chizuka following the incident between them, even though she allegedly wants to apologize to her. Noticing Chizuka's clumsy traits, Tomoe and Miyako decide to train Sumika into becoming a clumsy girl that Ushio would fall for, with poor results. Later, Ushio comes over to Sumika's house instead of going to meet with Chizuka. Sumika notices Ushio is lying about not having feelings for Chizuka anymore. Later that night, Ushio offers to wash Sumika's back, but Sumika just ends up fainting from embarrassment. Ushio berates herself for selfishly liking and then disliking Chizuka, but Sumika tells her it is not her fault. The next morning, Ushio goes to Chizuka to apologize and confess, much to Sumika's dismay.
