Its just as the tittle says, I really wanna read something different from the usual romance mangas out there....It can contain sort of category like "Age Gap" or "Incest" or "Social Hierarchy"...I don't mind sexually explicit scenes (even hentai's fine too as long as it has a good story)...

Yankee Shota to Otaku Onee-san
Kiryuu-sensei wa Renai ga Wakaranai.
Koi wa Amaagari no You ni

Thanks for your suggestions..
I've read everything except miman renai.
😀
please add some more suggestions...

Here's some:
Koi Kaze - incest
Velvet Kiss - social hierarchy, borderline H
Kanojo wa Sore o Gaman Dekinai (IWASHITA Shigeyuki) - student/teacher
Spirit Circle - reincarnation?
Emma - social hierarchy
The Voynich Hotel - supernatural
Kodomo no Jikan - student/teacher (loli)
Yasashii Sekai no Tsukurikata - student/teacher
Jigokuren - Love in the Hell - afterlife

Edit: wrong link for Kanojo wa Sore o Gaman Dekinai (IWASHITA Shigeyuki)

Otoyomegatari (Age gap, author of Emma
Mahou Tsukai no Yome (Age gap, demon/monster x human)
Otoko no Isshou (Age gap)
Blood Alone (Age gap)
Kimi wa Pet (Difference in power but not really social hierarchy)
Nodame Cantabile (Unconventional in that the characters are odd)
Beastars (One's a wolf and the other a bunny)

thanks mikako17 and sunder.
I really like Emma and Otoyomegatari a lot(the author)...
But what struck out the most for me were Kanojo wa Sore o Gaman Dekinai and Velvet Kiss...
I'll give others a try 😀
Btw I just found out Superior manga which is really good so far..

Cubism Love

Kore wa Koi no Hanashi - age gap; slow progression (one of my favorites in that genre)

I just finished this and kind of like this
Himegoto - Juukyuusai no Seifuku
A little twisted, kinda different and not for everyone I guess but give it a chance if you feel like to
