yes there's a manga for loveless

and i would say exactly what she did ^^. gravitation is a good start. then you can get into the more hardcores. some other good ones are:

only the ring finger knows
spells
be my slave
blue sky
gakuen heaven
junjou romantica
time lag (same author of only the ring finger)
yami no matsuei (descendants of darkness)
kyou kara maou (only the show is translated)
but you're my teacher
boku no pico OR chico to pico (these are shota/yaoi and are only movies)
okane ga nai

thats only the ones from the top of my head so yea good luck ^^. :vsign:
