This show surprised me, I did not expect it to be this good, i was only watching because i need to learn Chinese. But there were moments that really made me smile. Also, there are anime and videogames references and i think Razer was a sponsor of the series. I rated 8 to music just because there weren't OST that were absolute bangers, still everything was perfect and i almost binged the series, even though it's really rare for me to get THIS interested in tv series, not only regarding c-dramas. But I have one question for people that already finished the show... How did the police not question all their knowledge in the last cycle??
