Is it just me or is it guessing that it may be the emperor who is obsessed with him or the...

i don’t think so bc in the modern timeline, the emperor who was obsessed with him came to be his biological brother i believe

okay so not his biological brother. i might be wrong about that

Okay² just guessing here....

I'm guessing it's probably the assassin or the servant who ordered the assassin to kill him

same and it better be the servant, I can't with incest plots

Same, I hear incest, I close it immediately. But I think it's the reincarnation of the servant

spoiler!

I guessed right, I mean they all reincarnated, why not him also
