Friendly Rivalry Episode 11 peels back the layers on its most enigmatic character, Tae Jun, while pushing its central mystery into overdrive.
This episode isn’t just about finding Je-na; it’s a deep exploration of how twisted childhoods shape broken adults, asking the question: are we fated to repeat our past mistakes? Get ready for shocking reveals, character-defining flashbacks, and a cliffhanger that will leave you desperate for the next episode.
Friendly Rivalry Episode 11 takes a deep dive into Tae Jun’s childhood. A flashback shows him as a young boy, cutting a doll while a girl cried nearby. He couldn’t understand why she was upset.
As a teenager, his fascination wasn’t in eating fish but in cutting them open. Now, as an adult, even though he operates on human hearts, he still struggles to understand them.
During surgery, he notices Jae-i shares the same habit—cutting open dolls. This realization reassures him, believing fate wouldn’t repeat the same mistake twice.
This flashback is more than just backstory; it’s the key to his entire personality. His inability to understand emotions as a child (the crying girl) and his fixation on dissection (the doll, the fish) point towards a potential conduct disorder that has evolved into a detached, surgical adulthood.
The show brilliantly contrasts his literal understanding of “hearts” as organs with his complete bafflement by emotional ones. His connection with Jae-i over their shared habit is terrifyingly poignant—he sees it as a sign of fate, but the audience sees a chilling cycle in the making.
Back in the present, Jae-i and Seul-gi manage to escape. Jae-i reveals it was a trap set by Ah-ra. She tries to reach Je-na, but her calls go unanswered. Checking Je-na’s GPS, she sees the location is near her house.
Rushing home, she finds Je-na’s phone on her desk. At that moment, Tae Jun appears, reminding her to come home on rainy days or she’ll get sick. When she checks a box in her room, she realizes Teacher Woo’s phone is missing.
Bullying Scandal and a Shocking Accusation
At school, a drug abuse counseling session is taking place in the auditorium. Suddenly, a video spreads to everyone’s phones—it shows Jae-i bullying Na-li. The students whisper, and Jae-i smirks at the comments & shows no remorse or fear.
A detective arrives with footage from a metro station, showing someone involved in an illegal drug transaction. He asks if anyone can identify the person.
Without hesitation, Jae-i stands up and names Je-na, the eldest daughter of J Medical Center. The detective questions why Beom-su claimed Seul-gi was selling drugs. Jae-i responds that everyone hates the person who ranks first.
The detective later questions Tae Jun about his daughter’s whereabouts. Meanwhile, Ye-ri meets Beom-su, offering to settle the case quietly for money. She also sarcastically asked her about lying—why did she blame Seul-gi for selling the drugs?
Tracking Down the Truth
Jae-i and Seul-gi searched the school’s CCTV footage to confirm that Je-na was present during the anniversary event. They find footage of Je-na encountering Choi Kyung.
When they question Choi Kyung, she insists she wasn’t attending tutoring classes. Suspicious, they follow her, only to see her board a bus in the opposite direction of her usual route.
Jae-i assumes she has personal matters to attend to and leaves. But Seul-gi senses something is wrong and follows Choi Kyung to her own home. There, Seul-gi realizes Choi Kyung was the one secretly sending crayon-written messages. Jae-i arrives in a taxi and confronts her, asking what she wants to say.
Overcome with emotion, Choi Kyung accuses Jae-i of pretending to care about her missing sister. She questions why, in their six years of friendship, Jae-i never mentioned Je-na before.
Just then, Jae-i receives a call from someone claiming to know where Je-na is. They send her an address and demand she bring specific medicines.
Nightclub Chase and an Unexpected Discovery
Jae-i grabs the medicine from home. Seul-gi warns they shouldn’t go alone, while Choi Kyung suggests changing outfits to blend in. They return home and dress in short dresses before heading to the nightclub.
Inside, Jae-i places the medicine in the designated spot in the women’s restroom. Seul-gi keeps watch. Soon, a man enters the restroom and leaves quickly. Seul-gi chases after him.
Meanwhile, Choi Kyung stays behind and sees a woman entering the restroom. Sensing something suspicious, she climbs onto an adjacent stall, watching the woman closely. The woman retrieves the medicine from inside the toilet’s flush compartment. It’s Ye-ri.
At the same time, Jae-i gets stopped by Byeong-jin, and Seul-gi rushes back to help her. The chase takes an unexpected turn as they get closer to uncovering the truth.
THEORIES & PREDICTIONS FOR EPISODE 12
The reveal of Ye-ri as the one retrieving the medicine opens a pandora’s box. Here’s what we think might happen next:
-
Ye-ri’s Role: Is she the mastermind, or is she working for Tae Jun? Her offer to Beom-su suggests she’s the family’s “fixer,” but the drugs add a new, darker layer.
-
Je-na’s Whereabouts: The call demanding medicine strongly implies Je-na is alive but in trouble. Is she being held hostage, or is she a willing participant in her own disappearance?
-
Choi Kyung’s Revenge: Now that she’s confronted Jae-i, will she become an ally seeking the truth about her sister, or a vengeful obstacle?
