The story overall is just weird like how there is no reason for the MC being at the school since it's super prestige so you have to pay a ton to be there or be the best at studying. However the MC was someone who followed the crown prince of his country to the school so he could be an exchange student there for a short while but then the crown prince was caught cheating so he was kicked out and then for some reason the MC was granted a full education at the school. Later on when the MC also meets up with the main bully's sister who has gotten into a fight with her on/off bf for 5 years cause he cheated on her cause she will only have s*x after marriage. She almost instantly becomes his gf but then decides to marry him cause she's not getting any younger being already 25ish but the family will only agree to the marriage if they do a shotgun marriage. So she then is all for s*x (no points needed) to get her pregnant but then when they've done the deed she regrets it and becomes remorseful since she's now carrying a commoners child, yeah the MC is a commoner and most of the ppl at school are all nobles, so the child will be s*upid cause all commoners are s*upid. Since why else would they just work for the nobles and make money for them, so since she doesn't want "her"/their child to be s*upid it has to be a noble. But since he's a commoner it's impossible for the child to be a noble, but she doesn't wanna carry another mans child so she will therefore marry her ex-bf so that the child will also be a noble so win-win cause the child will therefore be smart since it's a noble.... but the MC doesn't have to worry since she will never let her ex-bf touch her and he will happily be a cuck to marry her since it's his life-long wish.

So yeah the story is kinda weird but it's smut so why not I guess?
