Under the steady mentorship of Fuutarou Uesugi, the Nakano quintuplets show a noticeable rise in their grades, though their journey toward graduation remains uneven. Yet each time they stir up new mishaps that postpone lessons, Fuutarou finds himself drawn deeper into their private affairs, adding further strain to their already tense dynamics. Their collective efforts, though fraught with setbacks, gradually build resilience among them.

The unfolding emotions test the boundaries of their roles, challenging both teacher and pupils.
