Romance tacked on

I got the impression that a focus group must have said, "Too many dudes, where are the girls?". The one young woman was very pretty, but she was inserted into the film just to show that the lead young man could be attractive to the opposite sex. Their exchange seems to comprise him trying to look down her blouse, her calling him out on it, and then she kisses him. Their romance is cut short due to another character's crisis at this Christmas party, and exit comely, young woman. I wish they hadn't included this scene and this actress if they were just going to go through the motions.
