As the headline says, it really is a one of kind series that is pure wonderful in every way. It's refreshing.
The plot exposes the entertainment industry's dirty secrets that only the insiders would know. This is a factor that would draw fans in because it's also a new setting other than your regular highschool/university love type of BL.
One thing I absolutely love about this BL is that it focuses on CONSENT, which is rare because many series have non-consensual scenes and people think it's okay. Nubsib constantly asking Gene for consent to kiss, hug, hold him, etc is really cute.
The cast is also a surprise! I didn't imagine 2 straight looking men would actually play a couple that would wreck the BL fandom. Love it!
The OSTs aren't my type so I would rank it lower but in each scene the music is suitable for it and makes it have more ~feel~.
Rewatch value: definitely would rewatch it someday when I'm bored. Just because it is that good too.
