I just thought of this while watching a k drama preview of some drama I don't know xD

Suggested Title: Last Chance or One Shot or a quote that says "You have only one shot you know?"

Plot: A young man witnesses a murder of the CEO's daughter, but before he could call for help, he was killed. But then, out of nowhere, he was given a chance. The chance that means he gets to go back to earth and find out why the girl has been killed... BUT. There's a twist. He has to be in another person's body because his body is long gone... And who is that person's body? The murderer. And the twist is that he doesn't have the memory of the murderer right away, only some of it.

lol you can get this plot if you want and edit everything because yeah xD

ALTERNATE PLOT: actually I was supposed to make the guy become a kid named zelo who also witnessed the crime. (and the twist there is that it was zelo who was the mastermind)
