Chuuya Nakahara He is a powerful member of the Port mafia, the mafia saw Chuuya as a weapon for his abilities but Chuuya was also the right hand of Dazai, the leader of the Port mafia and his duty as a bodyguard.It is to protect Dazai and serve the Port Mafia no matter how much it bothers Dazai. The organization was full of alphas and betas and Chuuya considered himself a beta. Dazai, an annoying bastard who Chuuya swore he would never get along with, yet he found himself as Dazai's right hand man and bodyguard, though that didn't make it any easier to deal with the brunet tease who enjoyed getting on his nerves to no return.The relationship between Dazai and him was strange since sometimes they have intimate encounters between them but Chuuya thought it was something casual for Dazai Lately Chuuya had been feeling strange, he felt like his body was changing, so he decided to take some tests with the Port Mafia doctor Yousano. What!?? What is this, is it a game? Chuuya said, hitting the table where there was a document that said Chuuya was an Omega and not a beta. Chuuya couldn't believe what the tests were saying. He was supposed to be a beta, not an Omega. And why was he feeling this way?

"This must be a mistake. There's no way I'm an Omega," Chuuya muttered under his breath, still in shock. Yousano sighed: I'm sorry to say the tests are correct, it's a rare case, but it seems your body has changed to that of an Omega. That's why I recommend you don't let them mark you.
