The girl looked at his side face as he was solving the problem seriously and said, "You know, we once told a story in our politics class. One day, flags were blowing in the wind. One young monk said it was the wind, and the other monk said it was the flags. The two argued endlessly. At this time, the monk Huineng said, it was not the flags, nor the wind..."
At this point, the girl stopped.
The boy also stopped writing in his hand, looked at her steadily and asked, "What is that?"
The girl looked into her eyes, her heart beat violently, and she stood up, "Huh, I won't tell you."
