Friendly Rivalry Episode 13 delivers intense moments as hidden truths start to unravel. Flashbacks reveal a crucial moment in Je-na’s past. Before her university exam, Kyung Ye-ri and Jae-i waited outside to support her. However, Jae-i didn’t wish her luck. Je-na always feared Jae-i, and during the exam, Jae-i’s laughter distracted her. She later wrote in her diary that she felt like a useless sister, desperate for her father’s love.
Meanwhile, Tae-jun discovers Je-na’s connection with Teacher Woo and praises her. At the same time, Teacher Woo’s wife was searching for Seul-gi, who had gone missing. Teacher Woo, still haunted by past trauma, refused to have children with his new wife.
Je-na later visits Teacher Woo’s house and sees a missing person poster for Seul-gi. Tae-jun then struck a deal with Teacher Woo, promising to find Seul-gi. He successfully located her and informed Teacher Woo.
A Dangerous Plan and a Startling Discovery
Teacher Woo went to the university for an exam committee meeting. As part of a plan, he took a pill with a small paper hidden inside. He later collapsed and was rushed to J Medical Center, where Tae-jun was working. Tae-jun retrieved the capsule, and Je-na took the pill.
Later, at Je-na’s funeral, Jae-i suddenly left the ceremony and headed to the morgue. Seul-gi followed her and revealed something shocking. The body was not Je-na—it was Cho Soo-jin, identified by a burn mark on her foot. Soo-jin had lived next to Je-na, making the situation even more suspicious.
Jae-i realized they had to act as if they knew nothing about Tae-jun’s involvement. But Seul-gi, determined to uncover the truth about her father’s death, needed evidence. Jae-i agreed to help.
Seul-gi disguised herself as a cleaner while Jae-i manipulated the CCTV cameras. Seul-gi sneaks into Tae-jun’s office, finds a remote, and discovers a hidden glass panel. Behind it was Jae-i’s study room, visible from Tae-jun’s office. She also found Je-na’s diary, which hinted that Tae-jun knew who the “good kid” really was.
While searching further, Seul-gi found a file dated November 15th. Inside was an X-ray CD of Teacher Woo, showing the pill inside his body. When the CD played, a song started, sending chills down Seul-gi’s spine. Overcoming her anger, she grabbed a weapon to attack Tae-jun. But just as she was about to strike, her stepmother stopped her.
Unanswered Questions and Betrayals
Tae-jun’s wife had long been suspicious of Je-na and Teacher Woo. She hadn’t signed a legal settlement for a reason. Meanwhile, Seul-gi confronted Byeong-jin, accusing him of knowing that the body was actually Soo-jin’s. He had been the one paying off all her debts. Their conversation turned into an argument, and Seul-gi later met Choi Kyung’s mother, a lawyer.
Seul-gi showed her the CD as evidence, but the lawyer said it wasn’t enough to prove how someone died. Seul-gi then revealed that there were many similar white file folders containing CDs.
At the same time, Kyung had a heated argument with her mother. Overcome with emotion, Kyung broke down, blaming herself for Je-na’s death. Her mother, however, urged her to stay silent and focus on her studies instead of testifying in court.
Ye-ri, on the other hand, was involved in something shady. She was seen with a club owner selling drugs. Later, she met Byeong-jin and gave him a recording of the conversation. She also warned him to be cautious of Jae-i’s father. However, someone was secretly watching Ye-ri.
Meanwhile, Seul-gi followed Byeong-jin and saw him meeting Tae-jun. Byeong-jin handed over the recorder, reminding Tae-jun of his promise. But before Seul-gi could react, a hand suddenly covered her mouth from behind, pulling her away. The episode ended on this tense moment.
What’s Next?
With so many secrets coming to light, things are getting more dangerous. Who took Seul-gi? What will happen to Jae-i and the others? The mystery deepens, and the truth seems closer than ever.
