Hello everyone.

A friend of mine watched a romantic movie about a girl who broke up with her bf. So she met this guy that was really into her but to her he was just a rebound. She was trying to find her bf in this guy. So told him they can’t be together and that they must go their own paths. But they have decided that they will write each other a love letter and in a year’s time they must come back to the same place where they planted the letters by a tree and they did and found each other…. it’s all I know about the movie I really hope that someone can help me to find a name of the character’s or the name of the movie.
