This series was recommended on reddit for its story & romance scene. I enjoy it & would say that it's one of the few good mini series.

What I like
1. Romance - I love it when male lead is attuned to female lead's needs and always prioritise her first. Love the scenes when he did housework. They are quite affectionate with each other. I also like second lead romance though I wish there were more scenes focusing on their growing romance.
2. Butterfly slave plot - Fascinating though I wish the writers had not gotten rid of it so viewers can see how characters accept the condition and become more empathetic.
3. Rain Lu - great acting. She conveyed various emotions well from innocence, delight to upset and disappointment.
4. Length & duration - I don't fancy historical drama but I like this series because it's short & concise.
5. Cameo - I like cameos from The Killer is also Romantic. Already have it in my watch list so I am going to watch that series next after completing this review.

What I dislike
1. The 3rd act - I feel it is too rushed especially the last 3 episodes. I'd like to know more about Lord Wu'an struggles.
2. Flashbacks - I know it's important as viewers got to learn about how Chengfeng & Qianyue's relationship developed but those episodes did not excite me.
3. Chemistry - There are many romantic scenes between 2 main leads but I don't feel much sexual chemistry coming from the actors.

Favourite scene
When Qianyue appeared as butterfly slave to Princess Baozhu. Beautifully shot & highly suspenseful.
