The Peerless Demon Queen, the Demon King Hugged Me and Cried

A cool seductress who takes pleasure in grudges and must avenge her, and who doesn't know what love is. A cold-hearted and cold-faced career-minded man who puts profits first and can be exploited for love. In a marriage ceremony, each signed a blood pact with inner demons for their own benefit, made ten transactions, and acted on occasion... Fake marriage, true and divorce. By a strange combination of circumstances, they unexpectedly had a baby, and they became entangled with each other.
