Delivery Man

Seo Young Min is a taxi driver who ends up with an unusual clientele - ghosts. Strangely, he finds himself exclusively ferrying these otherworldly passengers and granting their wishes. One day, Kang Ji Hyun boards Seo Young Min's taxi, but with a catch: she has no recollection of her past life and is unable to leave the vehicle. She takes it upon herself to become Seo Young Min's taxi's sales manager. Together, Seo Young Min and Kang Ji Hyun use the taxi to fulfill the wishes of various ghosts, even taking on the task of tracking down a serial killer. With the assistance of Do Kyu Jin, a handsome and diligent ER doctor, they try to prevent sinister events from occurring in the hospital. (Source: CK Warrior at MyDramaList)
