After a night of tireless contemplation and poring over crime scene evidence, Kim Sujin felt the weight of exhaustion. Yet, the existence of his family fueled a determination to delve deeper. The police called Lee Chayeon's husband to the scene, and when he arrived, the entire atmosphere stilled. Seeing his wife's lifeless body, he trembled, unable to comprehend the shocking crime. "Chayeonnnn," he uttered, breaking into tears.
After a long night, Kim Sujin returns home early in the morning, lost for words. His daughter Miso eagerly waits, oblivious to the storm her father faces. Sujin goes straight to his room after hugging his daughter. His wife follows him, confused, and asks, "Honey, what happened? Are you alright?" He responds, "No, I'm not. I came to change my clothes; it was a really long night." Then, he reveals the details of the crime. His wife, shocked, exclaims, "What? How could they do that? Who is that person?" Kim Sujin responds firmly, "That's our question."
Kim Su-jin went to work, searching for clues in the area where they found Lee Cha-yeong. However, the place, located on a deserted farm, was empty. Determined, he began walking in search of evidence. Suddenly, he spotted a small house hidden among the bushes. As he approached, he noticed it was made of wood and covered in dust. Attempting to enter, he found the door locked. In his quest for evidence, he saw a figure in the window. Startled, he was struck on the back of his head, causing him to lose consciousness.
When he awoke, he found himself face to face with an old man who, to his surprise, threw his gun and police card to the floor.
The old man studied Kim Su-jin with suspicion and questioned, "What are you doing here in my house?"
Kim Su-jin replied, "I'm here to ask you some questions."
The old man sternly ordered, "Get out of my house."
Observing an old photo of the man and his wife, Kim Su-jin inquired, "Where is your wife?"
This question angered the old man, intensifying his demand for Kim Su-jin to leave.
Undeterred, Kim Su-jin asserted, "Let me tell you something! A crime happened last night near this house."
The old man abruptly stopped, his silence hanging in the air.
