We Are Not Beasts(2022)

Oretachi wa Kemono ja Nai

Onizuka Raita and his younger brother Fuuta are infamous at their high school for being tough alphas who aren't afraid to take names and kick butt. It's also public knowledge that they're both down bad for Kazusa, a delicate-looking, pretty omega. Despite his appearance, Kazusa has an unwavering sense of justice and chivalry. He wishes that he could be stronger and not be seen as another omega in need of protecting, but his world is shaken when he gets his first heat unexpectedly, and his doctor announces that his fated mate is likely nearby. What happens when Kazusa's suppressants go missing and his heat hits when he's alone with the Onizuka brothers?
