These three words Song Chizhou are her nightmare, she loves him and hates him. Over the years, they have never ended. They have never promised to never give up, and they have never been heartbroken to separate. She knows that he has never let go, and she also knows that he loves her, so she wants to wait for him. Maybe as time goes by, everything will be just a passing cloud.
But now, she finally understands that she can't wait any longer. There can't be a good outcome between them. She can't look back, and he won't ask her to turn around again. They are like two intersecting lines. After a beautiful encounter, what awaits them is an increasingly distant separation. The two directions and the two end points will never intersect or meet again.
