Ariel von Retiana. − The princess who proposed a one-year contract marriage possessed the healing ability he desperately needed. Caius gladly accepted her proposal. In return, he planned to bestow many things upon her. It was clearly a marriage advantageous only to him. Until he learned the truth. The demon realm flower growing with her plant growth ability in the greenhouse was a plant that would kill him. “Did you enjoy it? Did you feel ecstasy watching a man suffer because of you?
