How Is Harry Potter An Archetypal Romance?

I have to read Harry Potter And The Sorcerer's Stone for my English class and talk about how it is an archetypal romance. I need some help. Please, if you have any ideas, like the archetypal hero, setting, or quest, help me out. When I say "archetypal romance", I don't mean romance as in love, I mean romance as in an adventure story. Don't talk about how Harry and Hermione love each other or anything like that. Thanks.

its all adventure all the way despite the homosexual cues.
