Tang Qianyu came to Japan on her own despite her parents' obstruction. On the plane, she met a man who was seated in the wrong seat. At that time, they didn't know that they would fall in love with each other.
----------------------------------
Tang Qianyu was overwhelmed by the sudden confession, and when she accepted him, she realized that she had become someone else's mistress!
----------------------------------
A sudden phone call made Tang Qianyu's heart plummet.
He just died and disappeared from her world.
----------------------------------
Tang Qianyu returned to China. She sat on the plane and looked up at the sky. The golden sun dimmed, and the man's peaceful smile appeared in the sky. The corners of Tang Qianyu's mouth also curved. She knew that he had always been by her side.
