all unless requested otherwise

treating friendship as "lesser" than romance
AUs that change the setting (coffee/flower shop, highschool/college AU)
AUs that change a character's backstory
on page rape/noncon
stories that are thematically about childrearing and parenthood
sickfic
unrequested crossovers and fandom fusions
