Most Helpful Guy
Girls see friend as just a friend. They become friends with guys because they enjoy their company, and their minds don't push it pass that.
Guys on the other hand, whether they admit it or not, will usually not approach a girl unless he finds her attractive or needs a favor. Think about it. He sees you for the first time, and he approaches you and wants to be friends. What do you think was the thing that attracted him to you? Couldn't have been your personality or character, because he's never met you or talked to you before. Of course the setting matters, if you assigned into a group for project it's much different than him voluntarily asking to be in your group. There's always an ulterior motive, some guys just hides it better than others.
