There’s a beast named “Deshi” living in the basement of the Alvard estate.

Selly feels sorry for Deshi, who is beaten every day, so she secretly talks to him and brings him food—slowly winning his heart.

But one day, Count Alvard decides, for reasons unknown, to get rid of Deshi. When Selly learns the truth, she loosens the iron chains binding him so he can escape…

“If you leave here, I won’t be able to see you.”

“We’re like that. Once we give our hearts, we can’t take them back.”

Realizing he can’t leave her, Deshi ultimately chooses to stay by Selly’s side, and the two of them begin a secret, intimate life together in Selly’s room.

And then…

“I like you so much, Selly. You’re adorable. I want to have you—every part of you. I want to devour you.”
