Maya divorced her husband and lives with her son Takumi. The two have lived together, but one day Takumi suddenly stays in the room without going to school. Maya, who couldn't see Takumi who couldn't even take a bath, invited her to take a bath together. Maya feels relieved to see Takumi, whose smile has returned to her bathing with her mother after a long absence. However, without hearing the truth, Takumi's classmate with a muddy face visited Maya, just as he thought he would wait until he spoke with his own mouth.
