Her family was poor and she was used to restraint; he was free-spirited and the center of attention everywhere he went. Two people who seemed to have nothing in common gradually drew closer as they spent time together.

If some people are destined to be unforgettable, was that love from back then a regret, or a story yet to be continued?
