This was actually my first ever BL series. The very first time I watched it I loved everything about it and was obsessed. However, when I rewatched it, it didn't have the same impact anymore. Maybe it's because by that point I had watched many other great BLs which in turn had raised my expectations.
Firstly, this series DRAGS for no reason. For more than half of the series, Third is mistreated by Khai who is supposed to be his best friend. Even if they were not lovers you still shouldn't be that shitty to your friends. Those episodes were hard for me to watch because I just wanted to shake Third and tell him that he deserved better. When Third was finally starting to move on I was very happy for him. Of course, that's when Khai starts to realise how much he values his friendship with Third. Not only that but he all of a sudden comes to terms with his feelings for Third too. This shift for me is the problem. It just felt unnatural and a little rushed. The screenwriters could have cut a portion of Third's heartache (which lasted for way too long anyway) and invested a few more episodes into actually developing their love story.
Other than that though the actors themselves were great. Gun is an incredible actor and Off's acting wasn't bad either though in their recent projects you can see how much he has improved. If you want to watch a series that will pull at your heartstrings, make you laugh out loud and scream internally from frustration then this series is for you.
Also sidenote, Un and Two were really cute but Bone's love story with his teacher was a miss. It was not only distasteful but very unnecessary too.
Overall this BL is better than most.
