In a dream, love starts with a stranger. Gazing at the scenic view of the sky, a man is joined by a stranger who informs him that he is in a dream. Unable to recall the memories of his life, he relies on the visitor to take him on a journey of discovery. Revealing everything—from their seven-year relationship to the emotional hardships they faced together—the two rekindle their bond severed by time. Behind this beautiful love story, however, lies a much darker truth.
