Sexual violence is an extreme trigger that can affect readers even when the book ends HE, and can directly re-activate personal trauma. This page goes beyond a yes/no list and tags three things explicitly: whether the content is depicted on-page in detail, only referenced as backstory, or implied; whether it shapes the protagonist's long-term psychology; and whether the narrative uses it as a character arc or merely as a plot accelerator.
If you want to avoid this entirely, skip every book listed here and consider making Happy Ending Books your default entry point. If you must engage with the material (a course, research, writing study), at minimum read each card's mild-spoiler layer first, and avoid stacking multiple titles in the same session.
For BL / Danmei readers this trigger often appears as "forced" or "dub-con" tropes — see BL / Danmei Warnings for that variant. For SA in YA novels see YA Trigger Warnings.
