The best yaoi is doomed yaoi that TRAUMATIZES me for life, absolutely destroys me, leaves me in physical pain, has the most heartbreaking ending ever, like, they've known nothing but suffering for the whole time and then it has the damn GUTS to show me an epilogue that's like yup, that's right, nobody is happy, nobody is moving on, nothing gets better, yes he still cries when he sees his picture, yes he didn't cut his hair in seven years cause he last touched it, yes he shows up as a hallucination in his room every day- how long has it been, you ask? Two decades. No, he will never love anyone else ever again and nobody will ever be happy again. Oh, they also watch the sunset longingly in different places at the same time and think about each other. Any questions?
