*** All of them are complete bl’s with happy endings. “You Own My All” is so sad, the MC dies a couple of times, but it all plays out well in the end. Anything by Usui Iroha is so good. I would go with that if you like some hesitation from one the people in the relationship due to their own issues.

This is good too. completed 100 chapters. The main couple go from friends to lovers after an accidental vampire transformation happens. The MC is such a strong willed person and doesn't hesitate to lecture immortal vampires that they need change their old ways because its causing an issue within relationships between humans and vampires. Good read! Even the buttheads have their own sad backstory. Everyone goes through it at some point in the story so they can finally heal from past wounds.
Im craving something angsty specific...
It can be anything angsty bl yaoi etc etc, something that can literally break ur heart to pieces. Something that can be stressful like Sand Castle or whatever. i just need drama
