You were in the royal family and a neighboring kingdom invited your family to dinner. After long conversations, you decided to take a walk in the garden and thought about the local prince whose name was Nishimura Riki. When you reached the pond, you heard a scream and walked quickly to check. A maid was lying on the grass in a pool of blood that stained her robe, and sitting above her... was the same prince of the Nishimura family with blonde hair.

"I really d-didn't want to.." He said quietly through tears.

Riki could not restrain himself and attacked his own maid. He drank her blood and made her already dead.
