In the shopping district, Mitsuki uses four tickets to spin for a chance to win a prize. She ends up winning a trip for two (her, and Yūya) to a hot spring. When they arrive at the hot springs however, Shōtarō, Moa, Yukina, Ayaka, Neko, and Nanami are also present due to Hiyori wanting to win first prize all four times. Yūya offers to carry Mitsuki's bags, but she declines. She gets this awful feeling though when he offers to carry Yukina's bags but dismisses it as Hiyori's connected feeling. Yūya sees that she is upset so to make her feel better he gives her some Dorayaki thinking it was due to hunger. When in the female outdoor bath Mitsuki refuses to undress due to the belt on her, Neko also wears a swimsuit due to a "family policy". While in the bath Yukina tells of Yūya's childhood and what it was like which makes Mitsuki think more on it. During dinner, Yūya goes to check on Mitsuki as she had been gone awhile. Hiypori suggests that she is jealous which she again denies saying it is the result of the synchronizing feelings. When Yūya goes to check on her, Mitsuki brushes him off saying she is fine. Tired of seeing her mope Hiyori then possesses her and heads off to the baths to see Yūya. When they arrive at the bath, both are shocked to see Yukina naked on top of him due to an accidental fall they didn't see. Yūya goes after Mitsuki as she runs off to say she has the wrong idea leaving Yukina behind who mumbles how dense he is. When he catches up to Mitsuki he tells her what really happened and comforts her saying that she is a nice person when she thought otherwise. Weak from the heart on her belt which suffered from the stress, he carries Mitsuki to the game room at the resort to rest which fills the heart more. While in the game room Mitsuki notices her Dorayaki that Yūya had given her earlier and unwraps it. Yukina approaches Mitsuki and takes a bite out of it, saying she is not going to lose to her. Meanwhile, Neko who is watching the whole thing thinks to herself that Yukina is getting carried away so she wants to shake things up a bit. (Source: Wikipedia)
