Our Promise (A Cethany Fanfic)

Connor Franta met this girl ten years ago during summer. When he had to leave she gave him a lock and she kept the key they made a promise to marry each other when they were reunited. Ever since he still has that lock. Yet he doesn't remember her face or name. Will Connor find that girl he met 10 years ago? Or Will he give up looking for her? Hope you enjoy :)
