The Monster's Bride

Hae-Na has been struggling to balance life and school ever since her father disappeared after winning the lottery. But one day, the appearance of some eccentric but attractive guys shakes up her world: Chae-Bin Do, a popular cute guy at school and a goblin, Yamagami Onisuke, a Japanese demon known as an Oni, and Wolfgang Lucifer Junior, a wolf-boy. They ask Hae-Na to be their bride and claim to have met her father: will she trust them? Where will these relationships lead her?
