One day, a reporter on the street corner asked a couple, "Can I ask you a question? When was the last time you kissed?" A certain man raised the corner of his mouth, hugged the shy female protagonist, lowered his head, kissed her lightly, and let go, "Well... Just now." The female protagonist was so embarrassed. The memory is still there, but the man and woman who kissed under the camphor tree did not say goodbye but never see each other again. Six years later, they both live in the same circle. She would rather never see him again, but she is afraid that he will easily and generously say to her, "After all, I was young, frivolous and ignorant back then."
