I read most of the good ones, liek Teru Teru x shounen (one of my favourites) shinobi life, Inu x Boku SS, The Result Of Being Reincarnated Is Having A Master-Servant Relationship With The Yandere Love Interest etc.
If you're familiar with these, you should be able to understand my type. I prefer the masterxservant relationship to be very relevant in the story and to get in the way of the relationship to some extent. I usually like it more if the boy falls in love first, and struggles between keeping his relationship with his master and his feelings. It's also a cherry to the top for me if he's possessive. I know this is quite specific, and I read pretty much all the good titles (I didn't mention everything cuz I forgot most of them xD)
But I'll be more than happy if you guys find something juicy for me.
I'd also like to add that I hate harems, no smut (excessive one at least) AND NO WEAK NAIVE female MCs <3 And I would prefer if the manga was relatively long 🙁

Thank you <3

Also check out the Master-Servant Relationship tag, I modified the search a bit to remove genres irrelevant to what you're looking for.

I have been waiting for this moment.
