Nightmare Building

One drunken night, Ha-seong dreams of spending an intimate evening with a mysterious man. The next day, when meeting a new tenant for an officetel contract, he’s shocked to see the very same handsome man from his dream, the one he had slept with?!

The man’s name is Ren. After Ren moves in, strange rumors begin to spread about the officetel. Ha-seong, unsettled by the stark difference between Ren in real life and in his dream, grows increasingly confused.

"What are you, really?"
"Who knows—what do you think?"
