About

Guest and Dongmin have been close since childhood, but both suddenly gained the ability to see ghosts and eventually perform exorcisms. Perhaps because of this, they both carry an identical small bell... To perform an exorcism, they must enter the spirit realm, but doing so drains their positive energy (Yang). If they lose too much Yang, they might lose control and do strange things at night, like killing people... The way to regain Yang is to be held tightly by someone who has plenty of it >< Because of this, they both pretend not to know each other at school.
