I'm looking for recommendations to the old style shuojo ROM manga, ex like romantic killer cliche sineros I saw the show and it made me miss all the old ones I use to read!

Romantic Killer is shonen parody of shojo, so are looking for things like:
Ouran High School Host Club and Kiss him, Not me

Or non-parodies like:
Kimi ni todoke
Wild Ones
House of the Sun
Kaichou wa Maid-sama

Both, I didn't really see host club as a parody tho. Romantic killer was with our a doubt but that's what made wanna see/read my originals again. I am talking like
st tail
maid-sama
kodocha
Itazura na Kiss
skip beat
special A
ones like those old school good romance weather it be school life of medical girl or fantasy
