The uke and semes all go to a prestigious school. They're childhood friends and the semes have found out that the seme is omega since they were young and decided to fake the information. After that, their school have a gender test and the uke found out being omega. But the uke's mom clearly hate omega since an omega stole her husband from her and the uke gotta keep his gender as a secret. In order to keep his second gender as secret, the uke asked his childhood friends for help, ect. And they even have a sequel where they get married and live together.

Don't expect proper grammar from me. I am not being paid here, so you get internal monologue in written form.

Thank you so much
