I can do romance (erotica is not allowed), slice of life, school, modern, and fantasy. Maybe even fandom, but it depends. If we involve romance into the RP, then we can do the following:

childhood friend x childhood friend
student x student
college teacher/professor x college student
elf x human
vampire x human
master x slave/maid
yaoi
yuri

If you have another idea for romance, then let me know.
