A wild, teenage heiress tricks her parents into letting her fly to S-Korea for a concert. But who could tell that half-way the plane would crash, that she'd be summoned to another dimension? Who can explain the new system that she has to host? Who could tell she'd fall in love with a demon and chase him all the way to marriage? And who could tell her that, the same love would break her? Would she allow that same love to heal her wounds?
