The protagonist Taichi, who has no friends, was despairing about forming a group for the field
Saki Matsudo, who couldn't let him be alone, decided to form a group with Taichi.

Mariko Honjo reads alone in the corner of the classroom.
Eri Sasazuka is busy playing around on her by herself.
Saki called out to the other loners like Taichi.

This hodgepodge group of individuals came together for the fieldtrip,
which ended with them breaking a "cursed pot" while fooling around inside the museum...
Taichi goes to apologize to the staff, only to be told there was no such exhibit, and returns home. He reflects on the strange day and falls asleep.

The next day-

"What is going on?!?!"
Taichi's shout turned into Saki's voice and resounded throughout the Matsudo household...

Every day these four people's bodies are randomly swapped by a cursed pot!?
Will this ragtag team be able to safely return to their original bodies...?
