When RyĆshi protects OtsĆ« Tsurugaya from a stray baseball, OtsĆ«, who is obsessed with repaying favors, becomes his maid and does all various things which makes him uncomfortable. While visiting RyĆshi's house to check on the situation, RyĆko and Ringo meet his aunt Yukime, an author who RyĆko is a big fan, who points out RyĆko's potential feelings for RyĆshi. OtsĆ« soon gets a fever from overworking and collapses due to fatigue. The others learn about OtsĆ«'s childhood, where she was protected from a car by a boy who died before she could thank him, resulting in her having a fear of being unable to return favors. Ringo comes up with the idea of having everyone dress up as maids and serve OtsĆ«, reminding her that there is no such thing as favors between friends.
