oh yo.. your brother is a hunk , dunno why you need to worry for
him.
Most important question hor..iss...
What kind of relationship is he looking for ?
Casual ? Long term ? Multiple ? Men-men ? or ... serious ( not
likely lah) ...
He's 22 onli... I think you are " Huang di bu ji, tai jian ji"..
worry for nutting lah.
