I don't understand the bad reviews, for me it was perfect. It gave everything I wished to happen in other bls.
I even binge watched the 10 episodes in one morning.

-The story was amazingly emploted. I had never seen a drama with this plot so it was very original and new, to the point where, even if I could predict some scenes, I still felt completely immersed.

-Usually, when the two leads fight, they make up after an episode just because, but not this one. The feelings where so well conveyed I was even feeling the same as the lead. One was angry and they fought, but later the other felt wronged too and that's not usually seen in dramas.

-The second lead couple was cute too. They didn't outshine the lead couple but they were certainly needed with all that cuteness.

In conclusion, give it a try. I really found this bl different from others in terms of production. It was very beautiful and satisfactory so it placed in my top 10 of dramas, not only bls.
