For now, I can only say that both the lead actor and actress are doing a fantastic job. They both seamlessly embody their characters. The male lead never even tries to hide the love in his eyes, but because of his cunning nature, when he's being the Crown Prince, he's one person, and when he approach her in another persona that his Crown Prince identity cannot do, he's another person (while always intentionally letting the female lead know those personas are the same person).

Personally, I really like it when a male actor has a look that is a little bit mischievous, cunning, competent, but also a bit scheming, and I don't mean they are a bad person, I mean they have a healthy relationship with her but they are just scheming, cunning, and good at planning. So I think He Yu did a really good job.

As for Meng Ziyi, I'm already not worried about her. The story is supposed to convey that she is a woman of breathtaking beauty, men fall in love with her at first sight, but because she has already died once, she is wary of trusting people, tells herself that she must be careful and ruthless with the villains. She chooses him only because he cannot harm her and makes her trust him.
