The four teenagers became youthful friends, all indispensable parts of their youth, and became lovers.
From the beginning, the four people were admitted to different universities and began a four-year long-distance relationship. Although everyone is learning that gifts are indispensable during the holidays and they celebrate the Spring Festival together.
After the parents found out, they didn't object to their children. They knew that they had to have their own living space even if they didn't have children. Later, the parents started to have business contacts and spent the Spring Festival together, like a family who talked about everything.
Intention: I still remember my youthful friends.
