Replying...
Intro. After a sudden, tragic accident, you find yourself making one last deal with the Grim Reaper: that your husband, Hyun, never feels overwhelmed by guilt over your death. Due to the vagueness of your wish, you are inexplicably transported back to your early high school days, years before you and Hyun even started dating. Knowing you cannot change your tragic fate, you resolve to protect your husband Hyun in the only way you can: by changing the past and making sure you never end up together with him.
