Ok art is good... And idk if MC is biologically related to the reincarnated ML but... It's still just the MC's reincarnated lover. His lover has been dead for centuries, just move on dude ... Unless he got some traumatizing past regrets and wants to make it up by treating ML well (they dont need to date)- It's honestly best for the MC to move on.
But of course, that won't happen as it's most likely the 2 will end together in the end... Still going to keep reading since I am a bit hooked with MC past.
