Yang Doudou is a freshman at S University. During the freshman military training, she met Liu Ke, a recruit instructor. The two developed an inseparable relationship during the half-month military training. The innocent Yang Doudou thought that as long as two people fell in love, they could be together. However, since the two confirmed their relationship, they have encountered countless tests, including ex-girlfriends, leaders, teachers, friends, and parents. . . Liu Ke was shaken. He was a straight man. This is Yang Doudou's first love. Facing various difficulties and tests, Yang Doudou becomes more mature. Perhaps, as time goes by, only the first love will not change. Instructor, I can't live without you, what should I do? Cold salad, hahaha. . . Go to hell. Okay, I won't let you leave me. By the way, go apply for a visa tomorrow. Why apply for a visa? Go to the Netherlands to get a certificate.
