Hello there!

I recently discovered Nana to Kaoru and Seifuku no Joou-sama which both deal in a psychological/mature way with the topic of s/m.
That being said, I prefer 'deeper' manga over the shallow ones and I'm more interested in the versions that include a dominant/sadistic male and a submissive/masochist female. Perhaps a manga that focusses on the struggles of accepting these kinks or an issue with their own identity.

I hope this is not too much to ask for and thank you very much for your help!

I'm not sure if I wanna do this
