Seong-won has been suffering from unexplained headaches for several days.
One thing is certain: this is not something a hospital can cure.
He ends up meeting Nuri, an upperclassman rumored to be the son of a shaman, and desperately asks him for help.
Thanks to Nuri, the problem seems to be solved—at least temporarily. Soon afterward, however, a ghost that has fallen in love with Seong-won becomes attached to him.
Wanting to grow closer to Nuri, Seong-won asks him to help keep an eye on the new spirit, "Mari," and the two begin spending more time together.
A romance between a man haunted by ghosts and a man who can see them!
