I am increasingly afraid this will be a "how to get over his death" story instead of a "how to prevent his death" story. He seems to be working through his grief, and it would undo all the character development if Je-ha lived.
Yep, I agree. It's like sort of a second chance but not really. It's just a chance for him to talk to his friend again, understand more things and finally heal. An alive Jae-ha is not part of the package.
