I must be thoroughly genre-broken given I anticipated the twist from the moment she sees Maki looking sad.
Regarding tagging: I understand the site staff generally prioritizes spoiler sensitivity, but I think it's worth considering reworking tag functions so that readers don't just stumble into things they'd rather not be seeing. Even something as small as letting folks hide the tags UI if they want to elide the possibility of spoilers, but also potentially enabling alerts set to specific tags so someone can back out even if they do have them hidden.
Knowing next to nothing about web dev, obviously I'm first to recognize I've no idea how much work this would entail. I do feel, though, that encouraging robust tagging is the best option in terms of community health. The potential of someone encountering content that can seriously fuck them up even using all information at their disposal is a shame.
