Oh I remember Ai no Kusabi! It was my first yaoi anime where both the mc and love interest died. :'((((
Ah, hearing you mention the old yaoi animes made me feel nostalgic again. You know what would make a good bl anime series even when it's an old story? Doukyuusei! The manga really covered their journey as youngsters to adulthood so well. I would give my soul to see the story have an anime adaptation.

Ai no kusabi is mine also first yaoi it was this introduced me to yaoi this is the only anime made me feel that that's how love between men are beautiful sacrifices and bittersweet but they deserve happiness I tried watching doukyuusie but never got into it cuz I was young and I love older relationships but one day i would give it a try , there are many good mangas that needs to get animated I hope one day ai no kusabi 2012 continues before I die.

I can't really say if it was love that tied the mc to the love interest in ai no kusabi. My memories of the OVA is vague since I haven't seen it for years but I remember their relationship being volatile and toxic.
Also, the story was really too short so their relationship was not explored fully at least for me. If it does get adapted, it's a good opportunity to understand their dynamics more.
Please do try doukyuusei! It's a really cute bl! But the manga explores more serious themes. They had so much ups and downs and it was a painfully sweet and heartbreaking ride that concluded with a happy ending! If you want some tasty angst, it's a good one.
Reminded me of Vassalord and that sexy vampire and his beloved priest. It feels sad to be nostalgic at 2:04 am.
