Lin Ye, an ordinary young man, works in a niche cafe in Beicheng, surrounded by a group of urban youths with different personalities. The frustration of entering the workplace, the reunion and separation of friendship and love, the conflicts in the original family, and the pursuit of life ideals are intertwined into a "half-full" life in the city. The four volumes respectively tell the story of the establishment and loss of friendship, the ups and downs and growth of love, the conflict between family and dreams, and the final self-reconciliation. Each volume has an independent yet closely related main line, and uses a humorous style to truly describe the sweet and sour life of modern urban youth.
