Story: I thought the story was pretty solid. There are different layers of subplots going on that all tie the characters together. I did find one of the subplots kind of forceful, like it had to be placed there for the purpose of continuity of the larger plot. But it didn't bother me to the point of disrupting my enjoyment.

The hate to love thing they have going on was nicely done. I like that I'm able to see the levels of emotion/feelings they have for each other change per episode. Visually it helps me understand how they developed those feelings and thus helps me enjoy when they express certain emotions later on.

Acting/cast: Jake who plays Shao Fei is my least favorite. His acting was not the best. There were moments when I thought wow, they let this make it into the final cut? I don't know how to explain his acting, I'm not an acting expert, I just know what I saw was not the best it could have been. Also, I don't know if this is how he normally is in normal life, but he does this thing where he pulls his chin out and his back and neck look like he has kyphosis. It's not a pleasing visual. Chris who plays Tang yi is alright. I think he and Andy, who plays Jack were good. He was able to express Tang yi well, although I did find some scenes a little exaggerated. Andy's character was a weird one, reminded me of someone who's a little kookoo sociopathic, but I think Andy did a good job since his character doesn't really express much emotion except smile, so it should be easy already, I assume. Kenny who plays Zhao Zi also did a decent job. He's the one with the least experience out of the 4 but he did relatively well. He was able to capture the niave innocent factor. However, overall, judging the finished product on all of their acting/casting choice, I think the finished product was pretty average. I'm not going to lie and say this was the best acting/cast I've seen because it wasn't, but the cast did well enough to get the story across.

Let's talk about the action portion of this drama. I have a gripe. Personally, I found the fighting very poorly choreographed. They all looked stiff. It was awkward. Fists were flying but they looked like they were flying in the wrong direction. I wish the fight scenes were more worked on because it's supposed to play an important role in the story. Cops and Mafia, c'mon, you should at least have epic fight scenes.

Something to note that was actually quite good about this might be their chemistry/ability to be professional about certain scenes. It wasn't exactly clear in the final cut, because characters have to be characters, so you don't see the realness behind their behavior, but the behind the scenes was another world. I loved their chemistry and friendship. Really great on that part.

Rewatch value: Personally I was really interested in Jack and Zhao Zi's relationship. Because they would have moments weaved in here and there, it makes you more curious what their relationship will turn out and that's where my attention was on. I would definitely rewatch this for Jack and Zhao Zi's relationship. The main story was alright but it's a one time thing for me. I wouldn't want to rewatch for Tang yi and Shoa Fei.

Overall: Yes if you haven't watched this, you should watch it for the experience.
