Some of you have too high expectations for this character. She’s doing the best she can with what little she remembers. She’s not some korean that got reincarnated. She’s a half nobel princess whose only lessons were to please her husband. Her going for Prince Kyle actually helped her gain information and stopping the ML makes sense when they’re surrounded by enemies!
Also the ML is great so far! He’s been through a lot but doesn’t use that as an excuse to harm her or disrespect her. He listens to her and compromises. The drug incident was disturbing for both of them and I honestly think the maid is the true annoying character. She’s not doing a proper job at all.
