Episode 5

The triangular relationship between the central figures in the case, Benjamin, his sister Rose, and Frank has become the key to the case.

As Beverly's fiancé, Benjamin should have been the focus of the case investigation.However, he appeared extremely vulnerable when questioned by the police.When he mentioned his engagement to Beverly, he burst into tears and the police had to temporarily abandon their in-depth interrogation of him.This makes people question whether there is an unknown secret behind his performance?

At the same time, as Benjamin's sister, Rose's role in the case cannot be ignored.Although she initially appeared very calm in front of the police, as the investigation progressed, her inner conflicts gradually came to light.She confessed the details of being called to the scene on the night of the crime, as well as how she handled the blood stains and crime tools.However, she insists she does not know who the killer is, casting doubt on her true motives.

Frank's past was also unearthed by the police.His record in high school, where he was sent to a mental hospital for beating a teenage girl with a wrench, attracted police attention.Under police questioning, Frank faced his past frankly, but he insisted that he had changed his ways and no longer caused trouble.He also revealed that Benjamin and Beverly's engagement was actually just Benjamin's wishful thinking, as well as the disharmony in their sexual life.This information seems to point to Benjamin as a suspect in the case.
