OTP AUs

• that generic college au where they're in the same class, dorm room, etc., and they're complete opposites/dislike each other, but one event brings them closer • your otp's roles/personalities reversed, so A has B's personality and B has A's • your otp have children. If they already have children, imagine them without them. Would they have pets instead? • post-apocalyptic au • your otp's relationship set some time in the past. What complications do they face?
