learning to be an omega // mha fic lol

thanks to mistukis (& masarus) bad parenting, katsuki doesn't understand how to be an omega. he doesn't know how to nest, he doesn't understand the meaning of nesting, he has no idea what scenting somebody means or how it's done. he's only been scented by one person before, and he was four at the time. he was kept away from them, his friend, izuku midoriya, after that. his parents neglected him, neglected teaching him things he should know. despite masaru being an omega himself, mitsuki, the alpha of the family, called the shots. masaru was allowed to be himself, to be an omega. only if he did exactly as mitsuki said as well, katsuki, on the other hand, wasn't given that chance. but now, being in the UA dorms, he gets that chance. he doesn't take it at first, not understanding why he should, what the importance of it all would be. but after rekindling his friendship with izuku, and becoming part of a healthy family pack, he finally let's himself be him. without an angry wall to hide how he really feels. he's just. him.
