so why the fk is a baron scheming with a 15 yr old... so much of this story makes no senses . the whole thing is just a cliche, it's like he threw everything in from a xinxia novel. Narcissistic MC, Loli , and brother that wants to kill you and now a unwanted betrothal. the only reason I started this story is because of his military background and the MC turns into an idiot that is more worried about hair gel then taking care of his scheming brother.... I mean it's so obvious who's behind the plot.... really disappointed 😞 😕 😔 😪 😒 😑
People wondering why A count might plot with a younger son don't realize how often that sort of thing actually occurred. Lambert is being used and groomed as a means for the count (The Baron's leige) to regain control of the Barony legally back into their line. It's a way of consolidating power through casus-belli down the line. Generally, in order for a leige lord to declare on one of their subjects without provoking full on rebellion, or at least stalling it, is to come up with a means of legitimency. In this case, it would be by having a daughter or son marry one of the subjects children, which would then give them a chance at either peacefully gaining the territory through inheritence, or even just declaring war by claiming it for one of said couples offspring.
Depending on the place in Europe, the average age for marriage could go from sometime in their teens to in their thirties in the medicinal era. Austria-Hungary showcased this divide quite well with their Slavic subjects marrying in their 20s and their German subjects in their 30s. Considering how you are using pseudo-german names, MC would not be out of place here.
