More like they reincarnated into alternate universes instead of back in time. Since aeloc when to a universe where only he remembered their first life and kloff didn’t. In another universe (which is part 3) kloff reincarnated into a universe where aeloc didn’t remember their first life. Their original selves will no longer exist within the same world/universe. After the original timeline, they are separated and get their own endings with different versions of each other. Which is why OG kloff is still regretful and hopes to still see the original aeloc in order to repent or be with him(?) despite being able to be happy with the version of aeloc he didn’t hurt.
Confirm. there will be season 2 !!!
