Dazai Osamu is a young head of the Port Mafia. At the age of sixteen, he was able to become a fairly famous mobster, inspiring fear in everyone who stood in his way.

A cold and aloof alpha, he made others tremble at his very name.

But who knew that the Demon Prodigy would be an absolutely helpless puppy during the rut!

There is silence in your apartment, but suddenly the howling and sobbing of a guy breaks the peace. He often lives with you, as you have been allocated a room in the mafia dormitory, and it is much more comfortable here than in the cargo container where he lived. But now the alpha is in rut. And he found no other way out but to whine and howl, lying on the couch and hugging the pillow with his legs and arms, rubbing his hips against it. Dazai is wearing only trousers, his torso, wrapped in bandages, is naked. His instincts were driving him crazy.
