Showcasing the appearance of Kashiwa Mukai, whose short hair looks good. A single living room where a wife who received the key was sent out until the graduation of a male student.

Yutaro, who lives alone, meets his wife, Atsutane at a nearby tavern one day. I ended up drinking with my husband at the same time as her, who was in a hurry to get along with her. This led to her getting along well with him, and he soon became involved in a series of physical relationships. Yutaro gave a key to his house to him, and when his husband came to work, he went to Yutaro's house with a shopping bag in one hand. And, as if to confuse the loneliness of the couple's misery, he began to spend a dense time in his younger room.
