Another review said it perfectly: as the "first" Korean BL the short runtime and few number of episodes makes it clear that this show was really to test the waters for the fans.

Good news is that the episodes are mostly 11-12 minutes, so the show is super binge-able. The story is incredibly fanfic-y, which you will either love or hate, but I really did enjoy the premise and the story for the first half of the show. I actually thought Han Gi Chan's acting was better than Eui Soo's, which surprised me. Personally, I also loved the character of a yappy brat that teases Gook, but I know other reviewers disagree and found Gi Chan's character manipulative and annoying!

My main complaint is that the ending seems SO unnecessarily dramatic and does a disservice to the first half. I think they could've ended it with the same "happy" ending feeling without ridiculous angst and drama that came out of nowhere with absolutely no build up. Also, I think the production was not super polished in terms of make-up and things of that sort (who decided to make Eui Soo wear colored contacts??), and the actors definitely feel too old to be playing high schoolers, and should probably be playing college students. Lastly, the acting chemistry between the couple was pretty good (not great), but the kiss was SO bland compared to what Korean BL shows are doing nowadays, that it seems like they really didn't want to do it, which is a shame.

Overall, it's definitely not the best BL show (or even Korean BL show) that I've seen, but I do have to give it a lot of respect as the "first" that paved the way for all the ones that have aired since!
