Sometimes the smallest action can reignite love and bring people together again across time and distance Bryce and Nora fall in love in their last year of high school. They worry about their relationship surviving after graduation but are separated sooner when Bryce’s father is transferred and Bryce has to leave.

Bryce promises to write but not in a conventional way. He promises to leave messages behind pictures in hotels where his father works. He tells Nora if she finds his messages, they are meant to be together. Years pass and Bryce leaves messages for Nora as promised, but wonders if it may be more of a habit than anything else. Bryce and Nora have moved on to other partners over the years and while Bryce still leaves messages for Nora, she has mostly forgotten his promise until she finds an old photo of Bryce. She begins to search for his messages and succeeds in finding one.

This action is enough for fate to trigger a series of serendipitous events that will bring Bryce and Nora together again— but at what cost and who will pay the price?
