wait, whats with that sudden proposal???!? i expect i would see some side BL story after k...

Okay so he is a noble and his family is going to eventually pressure him to marry. He doesn’t want to marry a woman who will not accept his sexuality. So instead he proposed to Bea beachside she understands and accepts him for who he is. It’s just like a contract marriage. It’s good for Bea because she is still a slave and if she doesn’t marry him there is a chance that she will be sold off somewhere else with no control over where she goes.
