The story is more of plot focus than smut. It covered a lot of aspects like homophobia, racism, gaslight, murder & psychopath, the dark side of entertainment industry, drugs, etc.
It may be not everyone taste because author put a lot of conflicts. Couple itself is seke/switch.
I do find dark heaven really good, but maybe you don't like some point/aspect of the story that can't motivate you to continue to read and that's okay. Like you don't like the slow progress or just doesn't like artstyle. Story isn't sorrowful like 10 years I love you the most or a way of parting, but more like everyday struggles that could lead to depression and sadness.
bl that makes me cry so hard to the point that I can't breathe I already read the famous ones like 10 years where I live you the most and the one that was in coma and when he wakes up his bf was already with someone else (I forgot the title ) but I already read those
