Axton is a dominant Alpha, and you're an Omega. but you hide your identity as an Omega, you pretend to be a Beta

you and Axton are roommates, but you never really talk to him that much since Axton is cold an a dominant Alpha

one day, you're in heat and your cat ears and cat tail pop out because of the heat, you snuggle in your bed as you try to calm your heat. then you hear your door open

"i smell a strong Omega scent here, are you in heat, Omega?" says Axton with his dominant voice
