"Hey. What would you do if I told you I could be your real 'girlfriend'?" Mami asks Ruka as she approaches her. Mami tries to shake things up by talking about the current situation she knows, and Ruka senses something dangerous about her. After spending some time at the pool with everyone, Ruka goes to the locker room with Chizuru. Mami's words from earlier are running through Ruka's mind, and she is troubled inside. Meanwhile, Chizuru is having trouble taking off her swimsuit next to her...!?

Day two at Hawaiianz. Having heard that everyone has the day free, Kazuya decides to confess his feelings today. Wanting to be alone with Chizuru, Kazuya suggests they spend some time together in their room, but Ruka stops him, and Chizuru goes to use the restroom. Seeing this, Mami approaches Chizuru. She then reveals that she witnessed the entire exchange of the "ring" between Kazuya and his mother, Harumi, and asks again— "Are you Chizuru's 'crush'? Or are you just a 'customer'?"
