Hmmm.. Liked it!!
It seems to me that she loved someone, but he had a significant other he had broken up with... But Jon (without h) tells her to not get her hopes high. "They always come back."
I also imagined the narrator/girl from another culture than Jon (without h) with the way she talk.
I agree with @jayna... your style in this story invites the reader to fill up the voids and imagine a story fit to them... I think it's one of the most relatable styles.
Wish she and Jon (with-- you know) become something "good" together~
They do, my friend, they do.
