The Landlord
The Landlord spies on his tenants closely, and figures out everyone's routine. However, he finds that Ying-ru has no discernible routine. He lets himself into Ying-ru's apartment to investigate while she is out, but Ying-ru returns unexpectedly, with a man. The Landlord hides, and watches as Ying-ru drugs the man with poisoned tea, then ties him up in the bathtub. However, the Landlord does not alert the authorities, and over the course of several days, Ying-ru tortures the man to death. A few days later, Ying-ru drags a bound woman back to her apartment in a suitcase, and also tortures her to death in her bathtub. The Landlord confronts Ying-ru, who says that she cannot accept a life without change or possibility. Therefore, she is determined to avoid a mundane life, and will shatter whatever boundaries are in her way. The Landlord takes her words to heart, and decides to shatter his tenants' routine lives.
