I would call that my dream guy! lolz! but i would say it would be obedient.

Insular, introverted or stoic
I'm not sure what it is called but i would guess seismophobia.
Yeah I'm pretty sure he would call you back. If you think about it any nice guy would. Justin is definitely a nice guy. I mean I wouldn't be so sure that he would call you back because he's a celebrity and what not.. But if he were a nice guy than yeahh most likely he would call you back!! :)
