The Promise Ring

Jane and louis started being bestfriends when they were 3 but then louis got to leave when they were 10, louis gave jane a "PROMISE RING" so she'll never forget him and a promise that he'll come back... after 10 years louis was already in a famous boyband 'one direction' but jane can't remember and still confuse if the louis in one direction is the louis that she had a promise ring with when they were 10...
