i am in process of watching it and so far nothing deserved under K-drama rating on it - just maybe the topic again is nothing bright, cheerful and positive, but that would mean kids were rating now :D
I am primarily and mostly BL consumer who happens to love Reverse or FreenBecky, EngLot and so on. And I know of many who live both GL and BL series. Statistically or unopenly you might be still correction your observation.
