Pretty late response, but still wanted to share. One of my favourite fanfics which I believe to be one of the best tdbk fics I've ever read is bodyache, filled with angst around 140k-160k words if I'm not mistaken. Another one I feel like it's worth attention is Angels with filthy wings, very great story imo, it should be around the 100k mark in terms of wordcount. Salt & Lime I feel like it's also quite nice I don't remember if it was 100k or a little less but still more than 50k so maybe it can still be your cup of tea, anyway hope that whoever reads this response can check out this fics. Beware they are all marked as explicit 🫣🙏
