Omg this is in my top 5 chinese dramas for sure! At first I was reluctant to give this a try, but i am glad i watched it. First of all, the cast are amazing. Their acting is 10/10 especially the main male lead. It's amazing how he immediately transforms between his different personalities. Also, I love how the main female lead was able to portray her emotions really well. It evoked my emotions so much just from watching her every time something heartbreaking happened. I think that this drama was also written very well and it is one of the most heartbreaking chinese historical drama ever; the way that the main male lead treated the female lead... I cried so much watching this. I was sucked into it from start to finish and omg I have to say that the clothes are so beautiful in this drama too!
The OST's are also really beautiful and it is really melancholic.
Overall I would highly, highly recommend this drama and I would put it in my top 5.
