What can I say? It's just that good. Definitely the most well-produced BL series I've ever seen. The only thing that comes close is the Sammon verse (Manner of Death and Triage), in my opinion. I really struggle to rewatch things, it's even rare that a series holds my attention the first time I watch it, but KinnPorsche really gripped me tight. I dragged like four friends into the KP rabbit hole with me, all completely different people, but they were always just as convinced as I was after I forced them to watch the first episode. I think that really speaks for itself. Just a really, really good series, both as a TV show and as a BL.
