Article 1 of the Tenant Agreement

In an apartment where pets are not allowed, the landlord's son Xiaoyang ignores his mother's warning and still often runs upstairs to secretly interact with Qingqing, the daughter of the drunken tenant. The childlike friendship that is budding day by day, despite the prohibition of Article 1 of the tenant agreement, privately raising cats has become a unique agreement between the two. One day, Qingqing was absent from school for no reason. When Xiaoyang hurried back to the apartment to search, he found that the pungent and strange smell had quietly revealed the horrifying secret behind the concierge.
