Slytherin's "scoring machine" little chaser Lily White fell in love with Gryffindor Quidditch ace goalkeeper Oliver Wood.
Why is my boyfriend (girlfriend) so sweet!
Me: Are you romantic?
Wood: I like romance. Although I don't know much about it, I can learn it.
Me: I like romance, I will teach you, and our every day will be very romantic!
Idea: Sweet enough!
