As the manga is ending I read a little bit of the webcomic (many chaps were missing) just for seeing the difference and I found out the reason Hori bit miyamura was because he came inside while they were doing it lmaoooo (that's why miyamura says it's revenge) also apparently it was Hori herself who told miyamura to come inside (god lord). Before having sex they also kinda talked about miyamura's self harm and stuff (like his piercings)

read chapter 49

On side note I kinda feel bad for Dylan I mean homeboy has fallen hard while Charlize is only using him (for now) but it's not really a bad thing atleast MC is not a weak ass poorly written character who loses motivation by the middle and falls in love with the person who killed her family or herself and marries the same person , overlooking all her trauma and misery as insignificant and showing it can be easily overcome like in many other manhwas.

She left you because you treated her like trash you damn fucking moron stop showing your surprised face as if you spent years loving her the last courtesy your trash ass self can show is by respecting her and not questioning her own damn opinion about her own damn life or accusing her. Damn what an ass and a waste of good looks. Being a dick till the end
i don't wanna sound misogynistic but the era(imperial like setting) the story is set in isn't it the legal male heir who becomes the head after coming of age even now isn't the wife only an acting head like isn't she temporary till the brother is an adult. the stepmom doesn't even have an adult son who might take the position lol so why are they acting so fucking dumb???
that's what I've been thinking that for to be head they need to exceed the family bloodline.
And it is normally the oldest son in the family.
