this is all based on what i have read, are reading, & dropped! i might not have every bl in existence here because i only started reading in 2024. if you want me to add a specific bl, please send me a message in alterspring telling me the bl name and what category/ies it falls under.
with the categories green, yellow, red, and black flag, these are the definitions i have for them and will follow:
green: in general, they have a healthy relationship: they communicate, don’t push boundaries, always ask for consent. tldr, a perfect relationship.
yellow: there are a couple of issues present, but they don’t affect the relationship too horribly. they can switch back to green flags pretty easily.
red: verbal abuse is present. the main char/lead is manipulative, isolates the main lead/char, insults them all the time, etc.
black: physical and sexual abuse is present. kidnapping, drugging, stalking, and more. basically, the worst case scenario.
for the other categories, if you prefer green flags and want to avoid red/black flags, follow this key!
