It's not worth paying that much if all you want is a light-hearted, fluffy BL story with pretty boys and some cute moments. But in that case, this is probably not for you anyway.
But if you want a masterpiece of LGBTQ+ storytelling that excels in virtually every aspect --script, direction, acting, dialogue, music, cinematography, pacing, realism, subtlety and depth, every single little detail, then this is worth every penny, if you can afford it.
I started watching it "elsewhere", but ended up paying for the official release -- all of it, even the episodes I'd already seen. Because if we want more content like this, on this level, then we have to support those who make it, if we can.
I you are hard up for money, you can pay for just one episode on Vimeo and watch the rest somewhere else. A little money for the creators is better than no money. If you are really broke, do what you have to. But if you have the means to support them, please consider doing so.
