It's a pool, it's a bathing suit, it's scary

Yu's down because Shouta moved away. It is found out that Yu is scared of the pool, so Kippei decides to take her to the pool so she can get over her fear. Kokoro comes to the pool as well and Kippei falls in love with her bathing suit, though he doesn't think she should wear it in public. Kokoro helps Kippei get Yu to go under water.
