From mlwhat I've read those are highly possible but never to main story, they always have a FL or something. That will be great and I'd love to read it. Since they story has to focus on the knight only ( and hope they don't make it harem with every character foolishly falling for them) with interesting side plots and the different ranks he attains
Those pure blood noble (¬_¬ ) can shut their mouth. If it weren't for their ancestors doing great deeds, their would have been born peasant too. Damn, even saving the empire isn't enough to become a noble, they're most likely getting rewards or backstabbing arc lolol "you're too powerful in this empire, we can no longer control you"
Can a knight become a noble? I rarely read story about knight so I have no idea. Let's say, they're a peasant birth but have an outstanding talent. I guess the emperor bestowed them a title. Starting from bottom to the highest rank
