I really liked this! My Hero Academia in an omegaverse world! Midoriya is an omega and asks alpha Bakugo to bite him so that he's not affected by his heat and can continue being a hero. Bakugo is frustrated by how Midoriya keeps him at a distance and fights his attraction to him. Then one day when Midoriya faints he decides to take care of Midoriya.
