Part 4

Hana, Kai, and Yume join Toshiyuki on a two-day, one-night trip to Kyoto to test the dating waters, but things don't go quite the way they planned.

The girls get together to vent after the trip, and Vivi confronts Kai, who then has a rough show. Hana's wrestling clothes get ruined in the wash.

Kai apologizes to Hana before his announcement. New member Reo, a pro surfer, eyes Vivi when he arrives, bringing a change of pace in the house.

Vivi bonds with Reo and makes plans with Shion; Yume proposes a trip to Sapporo with Toshiyuki. The house gets spirited during the Setsubun holiday.

Toshiyuki's Hokkaido trip with Yume approaches, but her closeness with Reo sparks jealousy. Shion and Reo each spend more time with the female members.

Yume gives her answer to Toshiyuki. Hana's matches get cancelled due to COVID19. Shion confides in Vivi who makes an announcement at a group dinner.
