He grants wishes to humans in exchange for their souls, but everything changes when he crosses paths with Do-hee.
After an unexplainable twist of fate, Gu-won loses his powers and discovers that they now reside within Do-hee. This surprising turn forces them into a contract marriage—one that’s more complicated and fiery than either of them ever anticipated.
As the two navigate their chaotic new reality, they begin to uncover secrets, confront enemies, and explore emotions neither expected to feel.
