Dongsoo is a loser, no doubt about it. He’s unreliable, unemployed, and he’s unlikely to be laid down any time soon. At least before he arrives at Geumsil on a train to Seoul. Short skirt and boob window apart, the way out of Dongsoo ‘s league. But it all changes when a train crash embodies Dongsoo and several other passengers on the train with a thousand years worth of sexual divine energy. The thing is, there’s only one way to unleash your steam. It’s time to hang out with your yang.
