Born seeing ghosts, Jong-eon grew up in a world of shadows. His grim reality flips when he pairs up for a college project with Hyeseong, a cheerful underclassman who somehow acts as a literal human ghost repellent. Desperate for a peaceful life, Jong-eon starts following Hyeseong everywhere to keep the spirits at bay. But when he gets caught red-handed, Jong-eon panics and blurts out the first excuse he can think of: he’s hopelessly in love.
