I rewatch this many times and it still doesn't feel boring because the crime scenes were unique with purpose and really dive into how criminal acts. The whole criminal group was perfect as it feels like the writer did not put it there just for the story but it feels like the criminal group has its purpose and is placed into the whole universe itself. I still have a little soft spot for A and T and quite sad that they had to..... "Spoiler" (once you watch it, you will know his fate).

Even though I love the romance and I can see their chemistry despite the sudden romance plot in the present moment like since they have memory loss and Han Shen went back only to find out that Jin Xi is a completely different person, there is also no records on the sister. What happens if the person who died is Su Mian. The romance is based on that kiss and one main sentence. a little unrealistic but passable, I was hoping that they just fall in love despite having no finance thing. It feels more genuine. Other than that there is no denying that the romantic chemistry is super good because even with the memory loss when they were working together, you get to see them still falling in love with each other. also, lowkey sad for S. The love triangle is sad from his end since it is a 1 sided love.

Even though you are not watching it for the romance, the crime situation that the team have to investigate is really well executed by the production and is well explained. That is the best part of it. i shall not further explain else it will be a spoiler. But you will not regret watching it. The friendship between the members is also quite good as well. You can see their teamwork and the way they complement each other skills and every character is there for a purpose!

You may feel confused at first but not to worry as the backstory of what happened 5 years ago will be explained in season 3 in the last few episodes.
