Shen Yu, a fresh graduate, moved into a new home alone, originally expecting a stable life, but ran into Zhang Jing, an overly enthusiastic neighbor. Upon learning that Shen Yu has ten thousand yuan in monthly living expenses, Zhang Jing proposed sharing expenses and splitting the surplus evenly. After being politely refused, the neighborhood conflict between the two gradually escalated. Faced with her life being disturbed and personal items being used without permission, Shen Yu did not blindly back down, but instead calmly recorded the facts, sought help, and guarded her living boundaries with clear evidence. As the truth became known to the neighbors, Zhang Jing's calculations could no longer continue, and Shen Yu regained her peace. This is an urban neighborhood story centered around money, boundaries, and respect.
