Years after a K-pop star saves her life, a fan learns of his death — but when she's suddenly transported to the past, she sets out to change their fate.

A powerful sorceress in a blind woman's body encounters a man from a prestigious family, who wants her help to change his destiny.

Butler Kim (Lee Jun-young), a man who replaces errands that start at 100 won per day, and Baek Dong-ju (Lee Hye-ri), a funeral director who grants the wishes of the dead, running an errand company.

In disguise as her friend, Ha-ri shows up to a blind date to scare him away. But plans go awry when he turns out to be her CEO — and makes a proposal.
