Echoes of yesterday

Arlo and Blair's love flourishes in a small coastal town, but Arlo's desire for adventure leads him to leave Blair abruptly. Heartbroken, Blair channels her pain into a successful writing career. Years later, they meet at a literary festival. Arlo, filled with regret, apologizes
and expresses his longing to make amends. Blair, still hurt, decides to make him wait the same
amount of time she suffered alone, leaving Arlo to prove his sincerity and commitment.
Their future remains uncertain, with Arlo determined to earn her forgiveness and Blair needing time to
heal. After 3 years they decide to meet again, in front of the river they met at 9 years ago, but where is Blair?
