At the beginning of the semester in September, four girls with different personalities accidentally moved into the same dormitory. Like four notes with different timbres, they formed a unique "quartet" in their college years. Some people are carefree and like to get into trouble, some people are delicate and sensitive and hide their worries, some people have clear goals and aim for the future, and some people enjoy their daily lives casually. From the awkwardness of the first meeting, to the late night chats about everything; from cheering each other up during exam week, to hugging each other to comfort each other when a love is broken; from the reluctance to shed tears during the graduation season, to the firm agreement when they go their separate ways - their stories contain laughter and tears, quarrels and warmth, and hide the youth and friendship that every girl understands. This is not a vigorous legend, but a gentle chapter about companionship and growth that the four girls spent four years writing together.
Purpose: Using the "quartet" friendship of four girls in a university dormitory as a carrier, it shows the power of companionship in youth and interprets the warmth of growth and the preciousness of friendship in ordinary daily life.
