It's a little weird but I think I understand the premise. In order to survive the youngest princess was forced to act insane for 10 years. The emperor, her brother, abuses her and her husband, ml, helps her regain her speech. It's obvious she's traumatised but I don't like how they're pushing the story. I get she needs to consummate the marriage so she doesn't end up back at the palace but I just can't get into it when she's acting like an actual child. Maybe it's just me, and maybe I'm the weird one because she had to regress so hard to survive, but I can't enjoy this storyline.
