A ladies' man Gareth is definitely not, as you can tell by his appearance. More times than you can imagine, Gareth has been unable to successfully land a girlfriend. And most of the time, the girls at his school are either "busy", and/or "uninterested".
Once he eventually gets the hint that the girl he's been crushing on isn't the right one for him, he decides to go after someone else. But given his stalkerish history, the girls will still not likely go out with him, no matter which one he goes after.
Perhaps Total Drama Alpharama will change the fortunes of a guy down on his luck. He knows that Mrs. Right is out there... somewhere.
