I love this one of my favourite manga and omegaverse
Takaba (alpha) transferred to a new job just to walk into his colleges having sex with an omega. It was a surprise for him to find out that the same Omega is in fact his boss, Karasuma. Takaba does not have the narcissistic traits that most alphas have and it a down to earth person but he does not like omegas due to trauma.
sequel: kurui naku no wa boku no ban beta . chapter 8.5 was hot shit
Kurui Naku No Wa Boku No Ban
