The only time where romance is even really brought up is at the end. The main girl spends 98% of the movie completely disinterested in the main character, then suddenly decides that she likes him towards the end. The main character never shows any real burning desire to help/save main girl, but only a schoolboy crush for a school idol that he never met. He basically does all that he does because he's a nice guy and feels responsible. For something to be defined as romance, there needs to be character development based around the love they feel for another character.
