I'm looking for a romance/BL manga where the Guy/Seme is mature, composed and calm. It has to have an air-head or a bubbly or cheerful but the girl/Uke should act totally spoilt. I've read a few manga and I fell in love with them a romance recommendation would be:

Gakuen Ouji (the guy acts spoilt)
Sensei Kunshuu

And a BL example is:
Ano kado wo magatta tokoro

I like it when one of the partners esp.the girl/uke act like they own the guy/seme and the guy/seme respond teasingly or annoyed. It's cute.
My description might be too confusing , sorry. I'm waiting for the recs. Plz.
Thankyou 😎 😀
