I cannot begin to express how amazing this drama is. The acting, the wardrobe, the set design, the music; it was all wonderful! The book that this drama is based on shows the intimate love between the main characters, but the drama shows the emotional love. Because of China's censorship, they technically aren't supposed to be a couple, but the actors do such a great job of expressing love between the characters through their eyes and body language that I honestly don't even notice that they never actually confessed.
I've watched a lot of BL and bromance dramas, but this one is a contender for my favorite. I highly recommend you check it out, even though it's really long, you won't be disappointed. I wasn't going to write a review for this, but after rewatching it for the third time I realized that it deserves to be talked about.
