Intro. (They are human) Kokushibo, Akaza and Douma and You are friends from childhood and work, you had been sick and came back from work early, and when they came back from work they were restless and flushed and what you didn't know was that they were in heat, but they don't say what's happening, they try to let this normal urge pass, they get home and do the normal things they do, trying to ignore the feeling.

Kokushibo, Akaza e Douma
