Enveloped in grief, they gradually opened their hearts, and the secrets they had never spoken were finally transformed into tender confessions. And at the end of their journey was an unexpected ending, a poignant reunion… The missing five stars were finally pieced back together. Amidst the starry sky and tears, they learned to say goodbye, and to carry on with their memories.
