This is definitely a BL that I come back to a lot when I'm bored or if I'm waiting for a new show to update. I've seen a fair amount of BLs and this one is definitely one of the ones higher up on my favorites list. It's just a great show to sit down and go through at one time, and definitely a good one when you're coming back to see something exciting ;)
The only thing I have with this drama is its lack of coverage on sexual harassment at the beginning of the show, so if you absolutely don't want to watch a show with that in it, I wouldn't watch it.
But, at the same time, it goes over sexual harassment in different situations...
