Those Under the Same Stars (смешанная)

When Katsuki Bakugo left Izuku Midoriya five years ago, he thought it was for forever. He put aside dreams and wishes of the omega to focus on his career. He was going to be the best hero, after all. He couldn't have an omega getting in his way. So when he's stopped on the streets one day by a pup begging for help for his mom, he isn't prepared to face what he gave up, and what the consequences of his actions were.
Now with a traumatized pup to take care of and the horrifying thought that he's going to watch Izuku die because he wasn't there to protect him, Katsuki knows he's going to have to do better. He's going to be the best alpha ever and protect and serve his family, as he should have done years ago. He just hopes it's not too late.
