Friendly Rivalry content in previous episode

Episode 12 of Friendly Rivalry opens with everyone discovering Ye-ri's connection to Tae-jun. Ye-ri explains that her family went bankrupt, leaving her destitute and living in a goshiwon (small boarding house) for a long time. Seul-gi thanks Ye-ri for honestly sharing the truth.

Meanwhile, Byeong-jin, now part of the group, realizes that Je-yi is the one who controls the drug market. He suspects that one of his girls, Su-jin, sold the fake cards he used to buy prescription drugs to Je-na.

At this moment, they find Je-na dead. Je-yi and Seul-gi go to Seul-gi's father's hospital to confirm the body. It seems that she jumped off a mountain, making her face unrecognizable. However, Seul-gi notices a yellow nail polish and a scar on the body's leg, which makes her suspicious.

Je-yi and Seul-gi go to see Je-na's body.

At the same time, Byeong-jin sneaks into Je-na's hospital room and finds the fake cards he had hidden.

Seul-gi is still haunted by Je-na's death. Meanwhile, Choi Gyeong receives the opportunity to pursue medicine, on the condition that she maintains her image as a model student, especially since both Je-yi and Seul-gi are embroiled in investigations.

To protect her reputation, Choi Gyeong sneaks into the CCTV room, where Ye-ri catches her deleting footage of herself at school after school. At the same time, it is revealed that Choi Gyeong witnessed Je-na and Seul-gi's father having sex but kept quiet.

Elsewhere, Je-yi has a nightmare about killing her sister. Seul-gi visits and finds her in a state of depression, blaming herself for her sister's death.

Determined to find out the truth, Seul-gi begins to follow Su-jin. In a flashback, she recalls seeing a scar on Su-jin's leg after she was bullied. Remembering the identical scar on the body believed to be Je-na's, Seul-gi is determined to verify her hypothesis. She meets someone from Su-jin's rehab center, who tells her the address of Su-jin's goshiwon.

Meanwhile, Ye-ri and Choi Gyeong investigate the medical lab at the school. They recall that Je-na was last seen there on the day of the school festival. The lab, which is related to Tae-jun's medical center, contains a clue—a piece of paper with the goshiwon address, room key, and room number.

Meanwhile, Seul-gi goes to Su-jin's goshiwon and learns that she has died. The landlord finds her dead in her room and is worried about the remaining money. Seul-gi also discovers that someone has been paying Su-jin's rent and debts.

Seul-gi then reunites with Ye-ri and Choi Gyeong, and the trio enters Je-na's room, which is filled with answers to math problems. The episode ends with Seul-gi noticing a locked diary and deciding to break it open.

Friendly Rivalry Episode 13 The Last Pieces — Friendly Rivalry Episode 13 Prediction

The locked diary that Seul-gi finds may contain important information about Je-na's death and her connections to other characters. These notes may reveal the true motives behind Je-na's actions, as well as the roles of those around her.

Episode 12 hinted that Je-na might still be alive. The unidentifiable body and strange clues (like the yellow fingernails and scars) could be part of a plan to fake her death. Episode 13 could reveal the truth about Je-na hiding somewhere.

Su-jin's death and the fact that someone paid her rent and debts may be connected to a larger conspiracy. Seul-gi and her team may discover that Su-jin was used or even killed to cover up the truth.
