Well according to some Shoujo Manga's I've read it can be Romanic when:

a) A Guy drives a Bike through the window onto your fathers head causing blood to gush out of his forehead, while he graps it and rolls around on the floor - all because he heard you had a cold.

b) Said Guy helps set up and buys you equipment so you can rob someone of thre most prized possession because you so happen to collect similar stuff. The guy gets extra romance points if he also distracts the man as well.

c) The Guy leaves for two weeks without notice and leaving you wondering whats happened to him or if he's just left you when he suddenly returns holding a book you so happened to point to once and said you wanted it - The Guy gets even more romance points if when he returns he has ripped clothes, bruises and twigs in his hair.

d) The Guy fights a 100 strong gang for you and is left as a bloody mess on the floor as you are left unharmed even when it was you who started all this mess anyway for being a bitch - though you'll spend ages shouting at him and explain to him why fighting is morally wrong - you secretly love the fact he put himself through all that just for you. He also gains super Romance points if he smiles at you while coughing out his guts.

This is what I understand romance to be. There's many other examples really but overall I think this covers everything.
