Mako Kawai, a university student, lived a life of quiet routine. That all changed with an unexpected invitation to join a club.

Mako and the other members received a directive: they must organize an event to demonstrate the purpose of their club, or face dissolution.

Mako and the group resolved to spend the weekend together, only to discover that Shinon’s funds for the outing had vanished.

After German class, Mako inadvertently collides with a girl who possesses an unsettling aura. Later that day, the same girl appears unexpectedly in the clubroom.

With Kurea and Shinon now licensed, the club resolved on a drive. However, their journey unexpectedly led them onto the freeway.

The club embarked on a day of shopping. While trying on a skirt, Mako was taken aback to discover it wouldn't fit.

The club excursion is underway! Following the train journey and the planned sightseeing, they intended to utilize the outdoor oven. However, rain begins to fall.

Nana discovered her runaway pet in a most inconvenient spot. And then, on a sweltering day, the club’s air conditioning system failed to function.

The club has decided to operate a food stall at the university fair, a development that means Nana will be assisting patrons.

The group journeyed to the hometown of Mako and Shinon. Mako felt a flutter of apprehension at the prospect of encountering her former companions once more.

Late into the night, three members of the club found themselves studying and discovered, to their dismay, that they had been locked inside the building. Subsequently, the club began making arrangements for a Christmas party.

The members convened, intent on giving their clubroom a fresh start for the new year. Amidst the dusting and tidying, memories surfaced, and they welcomed the coming year as a shared community.
