So... I've finished this series in two days and there is a lot of good but a lot of bad as well...

Let me start with the good things:
- The start of the series was really interesting. As a whole, the main plot (and I'm not talking about the romance plot line) is quite enjoyable to watch.
- The fight scenes are really well-done. I'm not an expert in fighting but I can notice when the production has made an effort to train their actors when they have fight scenes, and here is the case. I wouldn't say it is realistic because we still have things like an enemy who is waiting for his turn to fight the main character or the villain that waits before pulling the trigger. However, Sun's fight scenes were believable and really nice to watch.
- Pitch and Bank's couple. This is the only thing that I didn't expect from the story! I really didn't see it coming and was pleasurably surprise to see them getting together. I absolutely loved their scenes together and they actually had the best kiss scenes from the series.
- Boat's acting. Unlike Gun that I know from LBC, I discover Boat in this series and he's really good! He really knows how to act, fight, cry... He is convincing in his role.

Now, I'm going to talk about the bad things:
- From the middle of the series to the end, it gets boring. Maybe because they focus more on the romantic relationship between Sun and Sky but I found it a bit boring. And I really dislikes the end (I'm afraid to reveal too much but for those who have watched the series you'll know what I mean). Sky's father and the number of years were totally ridiculous.
- The clichés... I know a lot of BL shows use them but in this show, it was ridiculous and cringe. I really disliked watching them and was rolling my eyes everytime I saw one. They really should stop with that and try other ways to get the two main characters close.
- The fact that the boys used the girls' feelings. Ok, Juno was a bit too much hitting on Sun but at least, she gave him clear signs that she was interested in him. So why didn't Sun tell her that he was not interested in her? At least, she would've clearly known (even though it was pretty clear he was not interested but I don't blame Juno for continuing pursuing him if he didn't say anything). Sky, on the other hand, was clearly using Tortank (forgot the spelling, sorry) to get Sun jealous and I didn't like that.
- Gun's acting. I don't hate him as an actor. I kind of liked him in LBC but when he has to pull off emotional scenes, he's not really convincing (sorry). Someone already pointed that out in the reviews but everytime he has to cry or be angry, he shows his teeth and it kind of became ridiculous. Especially when he cries (if he really cries because I couldn't see any tears).
- The singing scenes. It was boring to watch the two actors sing, especially because they sing the whole song and we have flashbacks. Also, I'm really not sure they are the one singing and the instruments used in the series don't correspond to the ones we hear from the audio. It was really poorly done.

Overall, it was an ok series but the end really made me angry and disappointed (it is a happy ending but I hated some elements). I would still recommend watching the series if you have nothing else to do but once is enough!
