Train station.
Ning Xiang bid farewell to Ning Yu and Ning Hui.
Tears brimmed in Ning Hui's eyes, ready to fall, and as goodbye loomed, she could no longer hold them back, and they tumbled down.
A single tear, light and crystal clear, yet heavy as a thousand pounds, struck Ning Xiang's heart, shattering it into pieces.
He lifted a finger, catching the tear on her cheek, the moisture on his fingertip both piercing and scalding. He couldn't hold back any longer and pulled Ning Hui into his embrace, "Doudou..." Let him call her Doudou one more time, for the last time...
"Doudou, don't cry. You will always be Brother's most beloved Doudou, that will never change. On the days when Brother is not by your side, you must learn to grow up, to be strong, independent, and brave. You should always remain a happy Doudou like before. Don't you like drawing? Do you know that to Brother, the most beautiful painting in the world is Doudou's smile. Remember that, okay?"
