Ever since losing his parents in a tragic accident, Jin-sung has lived with a terrifying burden: he can see ghosts. Desperate to live a normal, quiet life, he hides his supernatural sight and struggles through the monotony of being an ordinary corporate employee.

Seeking a cheap real estate investment, Jin-sung purchases a run-down, abandoned building that happens to come with an old-fashioned coffee shop on the ground floor. But he soon discovers why the property was deserted. The “customers” wandering into his café aren’t human—they are eccentric, mischievous yokai and spirits.

As Jin-sung gets entangled deeper with his bizarre supernatural clientele, he is dragged into one wild, unbelievable escapade after another. Along the way, these chaotic encounters begin to unravel the truth behind his hidden “divine sight”—and the profound secret tying his own destiny to the spirit realm.
