Gabrielle could try to be around Harry as much as possible. She might join the activities he likes, for example, if Harry is into a certain sport, Gabrielle could start going to the games or even try to learn the sport herself just to get closer to him.

One possible plot could be Gabrielle's internal struggle with her feelings. She might be too shy to confess to Harry at first.
