"While Konoha is aware that he will soon be losing his book-eating club president when she ventures off to college, a new relationship blossoms between him and the once standoffish Kotobuki. The two even manage to spend New Year’s Day together! However, the dawn of the new year also ushers in the return of a familiar face — a girl whose every line Konoha has memorized and one the heartbroken boy thought he would never see again. Just as she reenters his life, though, Konoha feels the ties he has established with the people around him begin to sever… Can a simple book girl shed some much-needed insight on the situation before it’s too late?"
