alright well, idk if you've read nano machine, but the mc ends up having 2 official wives. His father even had multiple wives. The Mc in Absolute Sword Sense which takes place around 100 yrs before Myst, Might, Mayhem also ends up with 3 wives.
But Mok Gyeongwoon ends up with only one spouse (the blue spirit simply put)
when coming across a character like him, you'd think he'd have multiples wives/concubines but that's not the case.
It was a little shocking (pleasant ofc) to me that the same author of the other two didn't make myst, might, mayhem into a harem.
I hope that made sense. It was just a pleasant remark since i hate harems                                            

		
It's kinda crazy and refreshing how he's the cruelest mc in the verse yet he has no harem☠
his descendants should've learned that from him (yes I'm talking abt nanomachine)
