I’m hoping the author gives more clarity on how he became able… there was something said like “on his own” or “with no help” can’t remember the exact wording but I’m thinking it hints at some outside influence/s that changed his body. Which would make sense as this is a cult. Anyway, I need a bit more information, really want to delve more into the f*cked up psycho aspect of the cult.

So ML evolved or was in circumstances were he could reproduce? I think I understand that--even though the "how" feels confusing and complicated. I still have concerns, though:
1. We're gonna go the "seme must protect the seme" as so many series go.
2. Despite the bombshell, I feel like the narrative is still gonna focus on the MC and ML more than ML and his son, AKA the whole reason he hired MC. Heck, with the son being on the older side, they may not even end up involving him much and he just goes about his life.
