This concept was not bad at all. Wish they’d bring more of this style to Rebirth/revenge style stories. I think it would be interesting to show the MC story up to death then have them go into a waiting room where they can watch the life of the one they are taking over then in the final moments be like.
“Your life has been hell. Unfortunately due to those around you it’s over but I am going to take your place. It may not seem fair to you now but take solace in the fact that your life and death till now won’t have been in vain. Those that have wronged you will pay for whet they have done.”
