It was so aesthetically pleasing: beautiful lighting, clothes, and photography. The wigs were a bit :P, except for Lan Jue's. extremely interesting mystery storyline and cool detective work; I loved how all the cases were intertwined with the leads personal stories. Cool, diverse leads; all of them have satisfying character development and endings. Profound interpersonal relationships. They cared for each other in a very deep way, and the bromance was so on point. The beginning is a bit lukewarm, but it gets more interesting as the story unfolds, so you need to really give it a chance and trust the process. I liked the ending; it felt satisfying and thrilling without the feeling of it being rushed or having any unfinished plots. I wish we could see more of Kurou and Shulin's relationship and dynamic when they were children.
