hahaha that guy must try to find out what the girl likes, her
preferences etc... if you love someone and think that he/she is
worth, you would change for the better for that someone... but
again, don't over do it yeah... if not you would lose the original
you or turn that person off...
looks of course cannot change la... that one is bo bian... but
character can be slowly changed... but that's up to you yar... if
you think that you want or need to be accepted as the way you are,
then i suggest you look for someone who would do that instead of
changing yourself to suit someone's preferences which is pretty
difficult 
again, if the girl/guy shows no positive response, don't waste your
time yeah... move on... i'm sure there's someone out there who
appreciates you
