Luciel, the "Crystal Fairy," creates jewels whenever she feels strong emotions. After being used and ultimately dying, she finds herself returned to the past! "This time, I won't live like that again." To avoid the terrible fate she remembers, she proposes a contract marriage to the most notorious villain family in the empire. But something strange happens. It was supposed to be temporary, yet... "How about making you our daughter instead of just a daughter-in-law?" "I've always wanted a granddaughter. You're perfect!" "When I grow up, I'm going to marry sister-in-law!" Wait, aren't you supposed to be the villain family? Why are you acting like this? And then there's him... "Whether you create jewels or flowers, it doesn't matter to me." Belstein's reaper, the man who led her to ruin in her previous life, now smiles at her with a young face. "If you try to escape my sight, I'll chase you to the ends of the earth, Luciel." (Source: Kakao Entertainment Corp., translated)
