I'm gonna answer from reading experience: osananajimi tropes is frustrating AF because one, or even worse both, of them has to be extremely dense. "We kissed and had sex but if you don't like me as a friend then what???" *insert Soraya Montenegro screaming gif*

So yeah, if I had to choose between the 2, I had to go to possessive lover (with note, both are equally possessive). The more they're obsessed with each other, the better.
