He's being cornered into marriage with soomeone from the imperial family, remember? That means, the imperial family is trying to marry him to some imperial princess. The only way he can reject that is by marrying someone else who can resist becoming the imperial family's eyesore for a little while, and the FL doesn't have enough noble status and power to do that.

I've a feeling the ml is going to be trashy. How could he engage with another woman!? Like it's not that fl is a commoner tho, he could've just have her. I heard from comment section that the novel is not worthy, so SAD why always the good art manhwa!??!
