In the basement of the Alvard Mansion lives a beast named 'Deshi'. Seeing Deshi, who is whipped every day, Selly feels pity. She secretly talks to him and brings him food, slowly winning his heart. Then one day, Count Alvard decides to dispose of Deshi for some unknown reason. Selly, who learns of this fact, frees the chains binding Deshi's body so he can escape... "If you leave here, I won't be able to see you." "That's how we are. Once we give our heart, we can't take it back." Realizing he cannot leave her, Deshi ultimately decides to stay by Selly's side, and so the two begin a secret cohabitation in Selly's room. And then...... "I love you so much, Selly. You're lovely. I want to possess everything. I want to devour you."
