I like shounen ai but not yaoi...yeah...what's the difference?! yaoi is like hentai no story just disgusting love making while shounen ai had a story and simply shows the growing love between two guys which is more interesting...I'm not a hopeless romantic but I was kinda into plot...even if its humorous in nature but shows some love... I like it....that's why I love CLAMP they good at making shounen ai...but the downside is they don't write happy ending...

top 5 Favorite Shounen ai
1. legal drug
2. tokyo babylon
3. loveless
4. gravitation
5. monochrome factor

Though...i read all kind of stuff too...
