A female dog suitable for this room... Marina, a female doctor who is beautiful and highly qualified as a doctor, has lived an ideal life without any inconvenience, but is placed in a small and dirty four-and-a-half tatami room by two men who hold a grudge against them for unreasonable reasons.

After her pride and dignity as a human being are shredded by the men's confinement training, she eventually becomes an ugly and dirty woman who even thinks "I want to be a guy who looks good in this cage...". I was going.
