hehe.. this is gonna be very demanding~
The personality I often consider from a guy would be:
 How quiet he is --- I don't really like talkative guys. For some reasons needles to be stated.
 How alone he is --- I prefer lonely guys. Because they would learn how to appreciate friends or love ones better compare to the ones in the spot light. ^^ also an easier target.
 Serious and matured --- .... charismatic, pragmatic..... ^^lll I love this kinda peronality.... I don't care if he is a lame joker or can't even joke. As long as he cares for me ^^ I prefer silent love, silent personality and... everything silent. For it's far more mysterious than normal plus.. it's more exciting in relationships.. that's just how I feel. bah!
 HE HAS TO BE ODLER THAN SHEEP! XD or i wont even look at him ^^
