Much like "The Bad Kids", this is one of the best modern Chinese dramas I've watched. it started off a little bit slow and complicated but once the plot hit its stride from episode 2 onwards, it was such an addicting and enjoyable watch. The story is interesting, extremely well written and you never know what happens next, with little to no plot holes. The characters were brilliantly realized and acted - as a previous commenter noted, the chemistry between Gina Jin and Zhu Ya Wen was amazing; in all honesty, all the actors did their roles well. I would 100% recommend this drama if you're into crime, thriller, detective and whodunnit genres. There's a fair bit of romance too if you're interested in that sort of thing.
