Her evidence is bullshit and her line of thinking isn't exactly smart. Let's analyze the "evidence" she has:
1- He is mentioned as a suspect in the summary
1st Counterargument - Everyone who likes to read mystery novels knows that the author would never mention the killer as a suspect in the summary
2- He knew and disliked some of the victims
2nd Counterargument - He didn't really knew them all that well, and his reasons to dislike them where superficial. Also he has no link to the other victim and one of the ones he has a connection might have not been killed by the same person as the others.
3- The knot
3rd Counterargument - Everyone who went to his school (which is mentioned to be a very large academy) or was in the military has learned that knot and uses it regularly
4- He matches the description of the killer
4th Counterargument - That description is "tall and muscular" which might not even be right if the killer actually used poison first which is not a certainty since so many people know that knot so separate people might have used it
5- The original princess was supposed to die on her wedding night so he should have been in the room
5th Counterargument - He wouldn't have seen the original princess until their wedding so there was a good chance he wouldn't have even gone to her room that night
So she needs to start looking for connections between the victims, including the original princess. I wonder if the investigation that the nanny was making might had something to do with the other victims, and what was happening with the sugar thing. Was the maid finding some other sweetener that the restaurant and bakery used and the family that has the sugar importation rights found out? Or maybe it has to do with the magic crystals? I don't know, but so far the author keeps telling us she's a good investigator rather than showing to us that she's capable

Ikr?? I wish they'd focus more on the investigation rather than the romance aspect rn..
but well, one thing I disagree is that she's actually the one who discovered all those counterarguments you wrote (except for the first one lol). I think she's just trying not to be biased (and that kinda clouds her judgement a bit).

Everyone who keeps saying that she looks like his sister is making me laugh, cause the ML looks exactly like the wizard. This author can draw like 3 faces and 2 of those are for guys, so yeah, she looks like the sister since they have the same hair. Honestly I think it's pretty cool that the author is drawing a manhwa even tho they are clearly a beginner, that tells me that they were so passionate about the story that they just wanted to tell it and instead of waiting around they just went for it and that is commendable. Also at least the 3 faces they seem to be able to draw are really pretty, so I don't mind looking at them
If I had a nickel for every time a "technically not bl" manhwa had an mpreg storyline, I'd have two nickes. Which isn't a lot but it's weird it happened twice
Wait, when was the second
Maaaaaybe The S-Classes that i raised?? There’s this whole technically bio child of a guild leader and mc going on in one of the plotlines.
Even tho they're siblings?
Siblings??? Noooooo the child is between the Mc and Sung Hyunjae, the blonde guild leader not Yoohyun, mc’s like bro.
Spoiler for that, the sort of mpreg is when he tries to make a monster out of two mana stones I think so he puts them in his chest buy another guys mana is also sort of in the mix, so that it’s stable. But that’s not with his brother
I think I got a spoiler somewhere that he has a kid with his brother too. There's supposedly total of 3 kids. Idk who the 3rd man is. Damn I make him sound like a hoe
Noooooooooo why would they do that
Wait, whattttt, I paused reading that one to get more chapter and a mpreg appears (≧∀≦)
