One sunny morning, after Zheng Yiyi finished morning exercises, he met a male classmate walking toward the sun at the door of the men's room.
Later, Zheng Yi fell in love with him at first sight. He asked around about his shift and stalked people every day.
Finally, when he was about to graduate and leave, he blocked the person in the back field and forcefully kissed her. After the kiss, he ran away. She thought she would never see her again, but unexpectedly, at the graduation ceremony, the person who had walked toward the sun blocked her in the back field: "Zheng Yiyi, you owe me the first kiss you owe me."
