Hint: think about what the first two pages are showing.
No, seriously, I sympathise - I thought for quite a while about whether to do this one because of that final image, but after skipping ahead in the raws and reading some interviews with the creator I thought no, she's not just using horrible tropes for the hell of it or anything, is she? It's still pretty shocking, though, I agree, and made me feel... not great, a few times, working on it.
I might be wrong on this but - weirdly, from what I could gather, the original version in the Twitter manga is very different and pitches it as a girl-girl romance of sorts? It still has a tragic ending, but it's a different plot device altogether.
