A few ideas, some rubbish scribbled down as I go
1. A woman who's all talk in public but frigid in private, mouthing off about sex but actually a gentleman × a man who's an innocent flower in public but a philosopher in private
2. A naturally dominant woman who thinks she's purely lesbian, so dominant she doesn't distinguish between men and women × a man who was traumatized as a child, fears men, and becomes submissive: easily startled, fragile as a flower, timid
3. A gentle older sister who loves women × a proud, short-tempered man who gets turned into a woman-loving man
4. A woman in the dance department who seems unremarkable but is absurdly strong × a man in the oil painting department who's so dazzling you can barely keep your eyes open
5. A woman who seems like a bottom: matriarchal, androgynous style × an androgynous man who seems like a top
6. A woman who's pretending to be a bad student, half pretending to be a delinquent, and sick of the world × a real bad student who's obedient and loves life
7. A fake invalid who's actually a beast, a drama queen for twenty years who argues with people every day and has a sharp tongue, a black snake minister × a genuine invalid who's genuinely beastly, a pitiful man-starved soul, gentle as jade, the white dragon crown prince
Theme: Live happily and keep a positive outlook
