I was thinking the same too! But it seems they -the 3vof them don't remember their past lover and only the 4th Mugo has the recollection of it or something, and he might've saw that Mc is the reincarnation of their past lover cuz of the smell (omega smell or something)...
I really feel like there's something some one human mugo absorbed that was in that pot!!! They're one now but theyre weren't always!!! Flashbacks gunna go HARD
It was 1st mugo who feed him blood. That was shown somewhere in the beginnig. After he got awakened by the sweets. But yeah, 4th mugo seems to be the one who chose him and told him to bring sweets
And im just really starting to appreciate how amazing the writing is??
Honestly. I feel like there are 5 mugos due to the fractured 5 people that we see at the beginning of the series. I also 100% think MC is a reincarnation of his "criminal ancestor". That ancestor was definitely one of the mugos mate. Maybe two of the mugos. And the whole vengeance is spawned from his death. Maybe his own family killed him idk. That's why the fourth mugo saved him by telling him to bring something sweet. Maybe it was even the 4th mugo who fed him bood.
Also the parallels between mugo and MC with the candles. MC was also definitely struggling with some sort of inner split, and that struggle is representative of mugos struggle.
Hot smut AND GOOD WRITING
Peak.
