The Lost Chance

A boy committed suicide, but before his soul moves on, he is given a chance to see what he left behind. A girl longing for true love waits for him, seeing her causes him to want to stay. Living by her side as a ghost for a few months helped her feel his love and longing until one fateful day she meets him.
(For anyone who feels like there is no reason to hold on anymore, just know that there is always a reason to continue holding on).
