He asked: "Xu Yijia, when did you like me?"
Xu Yijia's eyes were bright and he asked instead: "I like you first, you have to wait until I ask before you can ask."
Instead of saying anything, he smiled, and the smile kept spreading to his eyes: "How did you come to the conclusion that you liked me first?" The final sound of the last word was elongated.
Xu Yijia bit his lip and thought, "I've been looking for evidence."
He flicked Xu Yijia's forehead and laughed: "Why do you think I finish school at six o'clock?"
"I always thought you knew the joy I gave you."
