Marriage of the Dead

Aki Niizuma works as an ending movie editor at a wedding hall, but she herself has only a negative image of marriage and has negative feelings toward both love and matrimony.
One day on her way to work, she picks up a mysterious red envelope and is forced to marry a ghost bride, Mei! The time limit for divorce from the dead is 49 days.

Can Aki and Mei find Mei's real "darling" within 49 days?
