The Wolf of Northern Darkness

A mysterious martial artist descends from the mountains with a single mission: repay his master's debt by becoming the live-in husband of a stunning CEO. But this is no ordinary arrangement. By day, he's the underestimated son-in-law everyone mocks. By night, he's the shadow king who controls both the forces of salvation and the criminal underworld. As enemies emerge from every corner of the city, they'll learn too late that the wolf they provoked has fangs sharper than they ever imagined.
