For some reason this kinda gives me “FOD” vibes (a BL light novel), if the male love interest was a bit more possessive, and the main male lead is a bit wiser, I could consider this a branch of the story...
So I’m enjoying the hell outta this

He goes through many lives, so at some point you’ll find a plot that you’ll love
Well I enjoyed it at least so I hope you will to :)

I hate her family using the “blood is thicker then water” quote, especially when it’s used out of context.
The full quote is actually, “the blood of the covenant is thicker then the water of the womb”
meaning the friends you make along the way are deeper bonds then the family you happen to be born with

A covenant is a legal issue, similar to an oath. In the context of the quote, the covenant refers to God's covenant to his people through the blood of Christ. Meaning the spiritual family you have in God, the people who have made the same commitment and sacrifice, is stronger than the tie with your biological family. This is especially true for people on countries where Christians are shunned by their families and killed for belief. Many people end up having to leave their families, not because the church forced them, but their families forced them. Friends will come and go with time, family will turn on you for ideas, but people who sacrifice everything for what they believe will always have a bond.

That poor girl just wants a home :(
She want her father to listen to her
She wants her mother to like her
All of her issues stem from an unstable environment, if the father loved her like the hero loves our mc, her heart wouldn’t be able to hate so easily.
They are setting the poor girl up to be a villain and I won’t stand for it
╥﹏╥

But isn’t a reason she’s not going to her tutoring sessions, acting out at school, and refusing to take the necessary steps to begin to fit into society, is once again because of her father and mothers bad parenting skills?
Her mother is actively teaching her to look down on others, while her father is neglecting her and her problems.
It’s a recipe for disaster that can be overcome if the dad just steps up as the parent he’s meant to be.
And if she still sucks after the parenting and stability, then it’s because she’s rotten to the core, and how she was raised can’t be used as an excuse for her actions

Yeah this is a problem with the manga.the manga got rid of a lot of povs and scenes like once the spoil prince was exiled the ex king confrontedthe crown prince realizing that was his plan and the prince told the king that he was a failureand the king and princess deservedthier punishment. In the novel her dad even though busy tries to teaches her and tell her what she is doing was wrong but she wont listen cause her mom is telling her her dad cheated (not technically a spoiler cause this happens in the novel at the same time in the manga her mom is rant her dad was second to the king so recent chapter of manga) on her so she listen to the mom more.like you will pity her dad even more after the whole school fiasco and the whole "cheating " thing is revealed.

Now I understand why she begun to hate her baby :(
To put it in simplest terms she treated the child how her husband treated her
With neglect
Yes he didn’t beat her, but he hasn’t done a lot for her has he
Does that excuse what she’s done to her son? No, it does give context though. And she’ll have the whole story to make it up to the son and apologise, I hope the husband does the same.

Okay that drug “white kill” is the last piece to my puzzle, so now I’ll give you guys my theory!
The crown prince is the father (obviously), and the brown haired duke is probably the murderer.
What I suspect happened the night our mc got pregnant is that the duke, gave our mc a small bit of “white kill” so the mc would not be in his right mind when the duke confessed. Leading to the mc accepting the confession and sleeping with the duke. But this probably fails because the mc somehow gets away, ooor crown prince steps in for some reason or another.
The crown prince either saving him or bumping into him run away, leads to the two of them to have some sexy time getting our mc pregnant, and it also explains our mcs lack of memories for that entire night.
The murderer; in the beginning we are told that this murderer is believed to be a noble and that’s the very reason why our mc needs help from the prince.
However it was found out that all the reports/letters he previously sent the prince about the case miraculously “disappeared” so I think the murderer is someone higher up on the nobility scale, because they can cleanly get rid of letters that were for the prince. Not just anyone can do that! Hence the duke.
Third, the black haired victims, a lot of the victims look kinda similar to the mc and I don’t think this is an coincidence. And the use of the “white killer” drug that’s both and aphrodisiac and a memory wiper, made me relate it to the night our mc got pregnant, which he can’t remember for the life of him.
And the reason for the killings. The dukes confession failed, and the drugs he used also failed, getting the love of his life to sleep with another man. Duke mad. Why can’t it be him? Why didn’t mc choose him? It’s all his fault.
So the duke takes his hatred out on people that look like the mc, until these fakes don’t satisfy him anymore and he’ll turn his attention on our mc.
Leading to a situation of “I love you so much I want you to die”
Or
“Be with me or die”
Or
“I hate you and your baby, we could’ve been perfect together, die!”

I think your right about the drugging and the escape from the person who drugged them and it being the opposite person who knocks up Mc. but I'm not sure if you have the cast right in who is the murderer. It could be the prince. Also a note to support my claim the murders tend to happen after Mc does something that upsets the prince.

That’s true the prince is also sus...
I agree that it’s pretty hard to tell between who will be the murderer,
The only reason I think the prince is in the clear is because he’s a main character and that isn’t evidence at all, especially when the prince can take a yandere route.
But we do know the prince is also obsessed with the mc, and since he constantly calls him his “white rabbit” it does make him seem suspicious.
But what’s the princes motive? We all assume that the mc slept with the prince, so he could’ve ignored the letters to get the mcs attention, who the prince thought was ignoring him because the slept together, rather then not putting effort into case in fear that he’ll get caught.
And if it was the crown prince the royal family would be doing a lot more to cover it up.
I guess that doesn’t rule out the prince setting a trap for the mc so he can truly belong to him
So it’s really anyone’s game

You know it would be pretty easy to come up with a compromise,
if that family is as powerful as they say they are maybe rent out a zoo on a day it’s closed.
If not they could always rent some petting zoo animals, the son seems excited about the bunnies and chicks anyway.
Or GET THE BOY SOME OP BODYGUARDS, give your child trackers (just in case), and if the dads that scared sprinkle on some more body guards on top.
Since they keep mentioning saviours being used by powerful countries for war, I’m guessing that’s foreshadowing this poor boys future...
He’s probably and innocent idiot who gets manipulated easily and will be used in war
Poor kid
yeah out bros good vibes will go in a bad direction
