Cha A Er Zhong: Nan Qin 501

Zhang Yi and Tian Ming settle into room 501, a boys' dormitory where late-night conversation can wander almost anywhere. Their casual chatter revives embarrassing school memories, childhood games, arcade mishaps, strange classmates, and the tiny incidents that once felt enormous. What begins as two roommates talking soon becomes a noisy, nostalgic portrait of growing up together.
