The girl could be the one with the 'wish' and the fear of having her heart broken. Or it could be about an older character who has been through a lot in love and is now hoping that this new relationship (implied by the title) doesn't end in heartbreak. There might also be a character who is a bit of a troublemaker in the story, causing some of the heartbreak - related drama.

One sad story could be of a terminally ill child who made a wish to meet their favorite singer.
