The Nakano quintuplets' academic performance is improving thanks to their tutor Fuutarou Uesugi's persistent guidance, even if their path to graduation remains tough. However, as they continue to produce numerous scenarios that prevent them from receiving true coaching, Fuutarou becomes more involved in their personal lives, thus complicating their connection. On a different note, Fuutarou gradually realizes that there may be a link between him and the history he feels he shared with one of the five girls. Will they be able to limit their tie strictly to that of a teacher and his students when their sentiments begin to develop and overlap, or will it mature into something else entirely?
