MapleStory : Path of the Hunter...?

The girl with the blonde hair is this whore who is hunting bosses and when you go and kill them instead, she gets all pissy at you. As you keep killing them and running into her, though, you save her life and stuff and you become friends.

I have NO IDEA about the chick/guy with the black hair. I didn't see that person ANYWHERE.

If the blonde girl only shows up in instanced areas, maybe its a gender thing? Male characters encounter her, and female characters encounter him?

Do I sense one of Japan's favorite archetypes sneaking into their version of the game? Of course, I mean the tsundere and I am generally for it. Otherwise, I bet the male? is a stoic, too cool to bother with your "silly little monster hunting adventure".
