My Billionaire Ghost Granny

A down-on-his-luck worker pays respects during the Qingming Festival, but accidentally goes to the wrong tomb and prays to the wrong person. A female ghost in red appears and mocks him, then calls him one of her own. The loser is bound to the century-old female ghost. With his Great-Granny's help, he reads Feng Shui, solves bizarre cases, gets revenge on his enemies, and makes a fortune.
