Aaaaaa's feed

I'm so into this natsusawa kind of guy. They are not the protagonist but they have this presence which I can't help but notice. They aren't loud but quiet almost all the time and they seem to be witted,smart, calm, and a bit introverted. Even irl I'm drawn to these kind of person, in fact I've dated two of these kind, not at the same time tho.
I don't have a term for it. What type do we call them???
