For me, the most important physical attributes would be a nice face (easy on the eyes) and ideally large breasts.
Personality wise, what I look for most is someone who is reasonable. Someone I can talk to about pretty much anything without fear of judgement or rash accusations.
I’m married, so I’m obviously not looking for a partner, but I thought this would be an interesting question, so I thought I’d ask.
I had something like that. Less yandere and more just loyal. It was somewhat nice but there was something unsettling about it, like she was so into me that I couldn’t trust her to give me her real opinion on other things that were bothering me because I know she’d just try and make me feel better instead of being honest.
