“So in the end, this contract is a contract where you help me.” Hajin has been constantly bullied since his school days simply because he is homosexual. In the end, he is given another chance at life by the angel Kael, who appears as if by fate, just when he wanted to give up on life, and agrees to the rogue angel's unfair(?) contract to give him his soul in exchange for getting rid of the stalker. But as time goes by, this angel...smiles more and more? A romance of mutual salvation between Kael and Hajin, who were lonely and had no one to rely on.
