Kim Hyun-joo and Park Hee-soon found their dead child's cell phone in their study.

In the 8th episode of the SBS Monday-Tuesday drama 'Trolley', which aired on the 10th, a conflict between Kim Hye-joo (played by Kim Hyun-joo) and Nam Jung-do (played by Park Hee-soon) was depicted.
On this day, Kim Hye-joo met alone with Choi Ki-young (played by Ki Tae-young). Although he knew that his wife Jin Seung-hee (played by Ryu Hyun-kyung) and Kim Hye-joo were complicatedly entangled in the affairs of Jin Seung-ho (played by Lee Min-jae), Choi Ki-young could not willingly step forward as a third party.

On the way home from meeting Choi Ki-young, the day was as bad as Kim Hye-joo's distraught mind. Kim Hye-joo, who saw the rain pouring outside the bus window, got off on her way home and headed to the book repair room. The rain and wind were so strong that it was difficult to even take a single step. At that very moment, Kim Soo-bin (played by Jeong Soo-bin) was walking in front of me. It looked like it was already drenched in rain. Kim Soo-bin remembered Kim Hye-joo's story of saying that she would stop by the book repair room to take a look when it rained a lot, and said that she was on her way to the book repair room just in case.
Kim Hye-joo hugged Kim Soo-bin without any response. He then said with tears in his eyes, "I no longer want someone to go wrong because of me. Mistakes cannot happen. Neither you nor your baby." Kim Soo-bin, who had recently been diagnosed with a pending miscarriage at the hospital, could not tell the truth.
The trolley dilemma discussed by her daughter Nam Yoon-seo (played by Choi Myung-bin) became Kim Hye-joo's own problem. While tearfully confessing the past to Hyeon Yeo-jin (played by Seo Jeong-yeon), she also expressed her concerns, saying that she understood the feelings of the perpetrator's parents after losing their son. During a conversation with Hyun Yeo-jin, Kim Hye-joo also learned that Nam Jung-do appeared on the news and mentioned the extreme attempt of Jo Gwi-sun (played by Won Mi-won), an oil house grandmother, to make an extreme choice. As expected, online news comments were full of malicious comments about the perpetrators, the parents of medical students at prestigious universities.

This was just thinking about the pain of the family left behind. In the end, despite Kim Hye-joo's request not to escalate the matter further, saying, "I am so scared and afraid that the tragedy will repeat itself," Nam Jung-do only repeated that he had no choice in order to revise the law as promised to him. Kim Hye-joo couldn't say anything to Nam Jung-do, who said, "There's nothing you can do for the bigger thing. You have no choice but to sacrifice the smaller side."
At the end of the broadcast, a shocking twist was revealed. Apparently, the cell phone that Nam Jung-do said the police couldn't find after his son Nam Ji-hoon's (played by Jeong Taek-hyun) accident was found. Kim Hye-joo was confused when she found this deep in a drawer in Namjung-do's study. An even bigger secret was hidden inside the phone.
This was Nam Ji-hoon's last conversation with Kim Soo-bin. Nam Ji-hoon's message, which started with 'Never tell me to break up with you,' ended with the short words, 'I'm going to die.' Next, Nam Jung-do in the congressman's office tells Jang Woo-jae (played by Kim Moo-yeol), "Ji-hoon died because of him," and Kim Hye-joo, who is in a state of panic over the fact that her son's death was not a simple accident, intersects.
