We are just ordinary men and women, talking about a college romance with a high breakup rate. The boy is not a noble and domineering CEO, and the girl is not a stunning beauty with a bizarre life experience. Everyone thinks that after graduation, we will get married and have children as a matter of course, and still be together. Even we think so. However, the road we walk together will always come to an end. At the fork in the road, we part ways, or we hold hands together and walk along an endless road. Many years later, you are no longer you, and I am no longer me. You look at me and smile, but I can no longer understand the meaning. I thought I would never forget you in this life, but everything is just what I thought. . . .
