On the September 5 broadcast of the SBS Friday-Saturday drama "Flex X Cop Season 2", the full truth was brought to light through a video saved on Moon Se-yeon's grandmother's cell phone.

On this day, the Violent Crimes Team 1 uncovered the truth behind the deaths that occurred at an arts high school. The person who killed the students was none other than Principal Jung Joo-hee.

The video that Moon Se-yeon left on her grandmother's phone captured Jung Joo-hee murdering Baek Yu-na, laying bare all the truth.

When asked why she killed the children, Jung Joo-hee started by saying, "Baek Yu-na was a bit arrogant." Prior to her death, Baek Yu-na discovered that her parents had bribed the principal to secure her selection as the lead for the arts festival, and she expressed her dissatisfaction.

However, Jung Joo-hee dismissed it, saying, "Just live off the fact that you have good parents." In response, Baek Yu-na said, "No, I want to be recognized for my skills. Turn yourself in. Otherwise, I will report you."

Reluctant to give up the benefits she was enjoying, Jung Joo-hee ultimately murdered Baek Yu-na. Afterward, Jung Joo-hee even resorted to drugs.

Because her family was poor and unable to bribe the principal, Moon Se-yeon had secretly recorded the principal giving lessons to Baek Yu-na. This led her to capture the moment Baek Yu-na was murdered as well.

Moon Se-yeon used this to blackmail the principal. Moon Se-yeon said, "From now on, you just need to treat me well, starting with making me the lead in the arts festival. Don't have any useless thoughts. I'm not an easy pushover like Yu-na unni. Once I get into Hankuk University, I'll delete the video."

Consequently, the principal made Moon Se-yeon the lead, but facing pressure from other parents, she decided to get rid of Moon Se-yeon. After hearing that she could die if she was unlucky, the principal planted drugs in a curse pouch that another child had prepared, which ultimately led to Moon Se-yeon's death.

Afterward, Jung Joo-hee also planted drugs in the bag of Ga-eun, who became the new lead, attempting to brush it off as an incident among the students. And the principal, who showed no remorse until the end, lost everything.

Joo Hye-ra had been continuously tracking Yoo Sung-won's movements. Upon hearing that Yoo Sung-won had brought a woman to his studio, Jin Yi-soo went to find Yoo Sung-won. He then sent away the woman who was nearly Yoo Sung-won's next victim.

Jin Yi-soo asked Yoo Sung-won about their past encounter. Regarding childhood memories that he could not remember, Yoo Sung-won said, "You were the only one who praised all my paintings, even though everyone else said they were weird. Do you know why? Because you're someone similar to me."

When Jin Yi-soo asked how they were similar, Yoo Sung-won flashed a frenzied look and said, "Your mom. I heard you were right there when your mom passed away. Did you see that exact moment when the soul slipped out of those eyes?"

Questioning the timing of Jin Yi-soo's visit, Yoo Sung-won found all the cameras installed in his home and disposed of them. He also suspected Jin Yi-soo, wondering, "Did hyung get won over by Joo Hye-ra?"

Realizing that he could no longer keep an eye on Yoo Sung-won, Jin Yi-soo changed the location of Hansu Group's high-altitude drone, allowing him to continue monitoring Yoo Sung-won's studio.

Meanwhile, towards the end of the broadcast, a murder took place at Jin Yi-soo's home, and evidence pointing solely to Jin Yi-soo as the murderer was revealed, raising curiosity about how the story will unfold next.
