beta
Uke was raised NORMAL. Suddenly turn over his life, he became dominant omega, the future Crown Princess. The two thing is sky and earth. You can't wait from a normal men who belived he is a beta and a normal person, to be happy having obligations, duties, what he never learned, and they coming with the title of crown princess. He worked hard to study architecture, so hr can do what he love, then he got a sentence: let be that a hobby, you have more important duties....so his whole life until (learning, friends etc.) now is nothing but a hobby.... Hell no, you can't just accept these kind of things just like this, useless you are half crazy.
The 1st problem lies in MCs parents. They didn't say anything to him, raised as a normal people. If he just know these things, then there would be a bit easier to accept this situation.
The 2nd. The CP don't understand his situation, he was not prepared to handle a normal person who do not know anything, and do not want to do with this whole thing, just wanna live his normal life. He do not know what to do, how to explain the things in a way that the uke don't scared half death, or get angry.
