Jiang Yi ignored Yu Huai, who was still standing there, baffled, and kept walking. Once Yu Huai snapped out of it, he hurried after him, hooked an arm around Jiang Yi’s neck from behind, and pulled him down a little. They were so close that Jiang Yi could have kissed Yu Huai on the cheek just by turning his head.
Yu Huai wasn’t thinking about that. “Hey, classmate. I think we should get to know each other all over again and forget about the unpleasant things that happened before, okay?”
If you don’t forget, I’ll stab you.
But he needed this guy to tutor him, so he could only slowly make up for his bad first impression.
With that, he removed his arm from Jiang Yi’s neck, then held out his hand with a smile. “Hey, classmate. I’m Yu Huai. Nice to meet you.”
At that moment, the boy seemed to meet his younger self from more than a decade ago. That summer, the breeze was like poetry, fiery and unrestrained. It swept away the heat and stirred the young boy’s heart.
Jiang Yi reached out his hand, met the boy’s gaze, and said, “I’m Jiang Yi.”
Actually, it's not badly written, but Yu Huai's rambling is too dense; basically, every question mark is followed by a description of his inner thoughts. I can't really explain it, but that's the general feeling.
Anyway, I think it looks really good.
