There are three of the Minami sisters: Haruka, Kana and Chiaki, who have an average life. The girls only have each other to depend on and help each other get through everything from love confessions to cooking.
The everyday lives of the Minami sisters continue. Chiaki, the youngest, continues to call people idiots while worshipping her eldest sister. Kana, the middle, still can't figure out that Fujioka's feelings for her are a crush, not a grudge. Haruka, the eldest, still unknowingly avoids Hosaka's advances to invite her to the volleyball team, and after a long day of excitement, the sisters enjoy sitting at the table at their home.
