Wait, if only the royals can impregnate men, and there's only two royals (the white hair and the considerate Duke earlier), then how did the serial killer impregnate the ML, assuming it's the serial killer and the serial killer is neither of the two royals?

No there is more royal, it is just only a couple of them could be able to impregnate the uke because the other weren’t at the right age (maybe too young). Go back to chapter1, I think they mentioned 3 name of royal at the right age, not including the prince because uke and him at odd. Then assuming your theories correct the murderer impregnated uke will mean that he has royal blood.

I feel like authors writing these stories are the kind to dismiss rapes cuz the victims must've secretly enjoyed it or whatever. That's the message this series and a lot like it is sending. It's ok cuz the uke secretly enjoyed it, even though the uke obviously didn't consent and was freaking out during the act.

that's the only somewhat forgivable part about it that i can remark upon, that Lukas (seme/alpha) felt remorse about forcing himself on Lee Rain (uke/omega), sincerely apologized, said he'd make it up to Rain by keeping his distance and has KEPT his word. (︶︿︶)
Now if other creators could get this really important giant memo to incorporate similar themes in their own works, especially when it's between the main pair

This is available for free on Pocket Comics btw.
I'm looking for this. Do you have link?
I don't have access to my phone rn to check the app; but according to bakaupdates, the title on PocketComics should be Talk to Me Tenderly.
I already found them! Thank you so much for mentioning it. It's worth it.
