If your thinking about that one reputation where everyone hates you,this is not the one.
Having a low reputation means not being hated as much,so at least you don't have to worry about anyone hating you or bullying you.
Also,because of having a low reputation,means no one isn't gonna hear about you in drama,rumors,nor gossip leaving no dirt on you when you graduate.
So if anyone tries to blackmail you,well they basically can't do it because of being too much of a baka to realize they can't do anything because of having nothing.literally.
Also,no one really notices you,meaning you have peace and quiet to yourself while the rest sorta have to deal with all the drama and gossip they have to face with having a average or popular reputation.
But,because of people not noticing you,if your absent they're not going to know your absent until your friend says something about you being absent.
Also,This means you can focus more on schoolwork if your that type of person who has those parents that will literally ground you because of one or two bad grades on a test,That type of person who does good in scholowork to have an excuse because of their siblings,or that person who does good but thinks they need to up their game.
I've been a introvert since the beginning of school,and so far I only talk to my friends and people who used to bully me because of thinking I'm mute,don't do that anymore.
