I think this is a great Taiwanese drama series. I’ve watched some Taiwanese BL and this is certainly one of the best because of the production and acting; also one of the best HIStory stories.
The characters were really interesting and funny, I think that’s a strong point as well as the acting, the main characters acting was really good. The chemistry between Tang Yi and Shao Fei was outstanding, they definitely did an amazing work portraying the characters and the love scenes.
I loved the secondary couple too, Jack and Zhao zi were so cute together.
The plot was really interesting and thrilling, I was invested into who was the actual murderer, and I liked that it wasn’t that predictable; at least for me, I didn’t have any idea! Lol
The music was also good, I would say average since it wasn’t very appealing to me, but there are definitely some series that have actual bad music, this was okay.
Overall, I enjoyed it a lot. The characters grew on me, the acting was on point, and the mysterious plot and production was what carried the whole story.
I don’t think I have negative opinions about it to be honest, not my favorite but it’s definitely one of the best well developed BL stories out there.

I recommend it if you’re looking for some action, enemies to lovers mystery BL, and also if you like mafia/ police themes!
