One thing I feel like is already going well, is the balance between all the characters. There's 6 main characters, and not necessarily a massive amount of time to give them each the attention they need to develop. But the show did visual story telling, a lot of showing to give you an idea of their personalities and motivations. It doesn't spend overly long on any single person giving each character a proper introduction and directions on where their journeys will head.
This story is a bit unique among BLs, generally a lot of actions of the characters might give the whole "this is sweet, butterflies are in my stomach" when the characters flirt, etc. But, us as viewers, have an idea that nothing we're seeing right now, can exactly be taken at face value. Secrets, conflicts, and maybe betrayals await. As I mentioned to @Drew Espinosa elsewhere, I can't drop my guard at any point with this series.
