Japan's best-selling high teen novel!! A charming series of events unfolds with the new members of the Sanbaiyukai at a refined girls' school! At the start of the third semester, Yumi reunites with Toko after being rejected for a sisterhood proposal about two weeks later. When Toko greets her first, Yumi can only respond with a simple, "How have you been?" and finds herself unable to say anything more. Yumi, Yoshino, and Shimako naturally put their names forward, but just like last year's Rosa Canina, a major incident is waiting for them this year too…?!
