What is the plot?

Woo Seul-gi and Yoo Jae-yi search desperately for their friend Je-na to testify about the truth surrounding her father's death.

Ja-e-ni's life is turned upside down when Tae-jun threatens Seul-gi's life, demanding that Jae-yi becomes the obedient daughter her father expects.

Tae-jun reveals that Je-na's frail, near-death state is the result of a chilling plan he orchestrated to silence her.

Je-na, weak and terrified, is found by Seul-gi and Jae-yi, but her ability to speak clearly is compromised by Tae-jun's prior actions.

Tae-jun confronts Jae-yi directly, presenting her with a brutal choice: protect Seul-gi and Je-na, or save her own family and her future.

Jae-yi agrees to betray Seul-gi and Je-na, choosing to be the obedient daughter her father demands, and seemingly abandons her friends.

Seul-gi watches Jae-yi's betrayal in shock and heartbreak, realizing the depth of Jae-yi's fear for her own safety and family.

Tae-jun forces Jae-yi to participate in a scheme to discredit Je-na's testimony, ensuring Je-na's story will be ignored.

Je-na, despite her frailty, manages to hint at the real killer of her father to Seul-gi before being taken away again by Tae-jun.

Seul-gi realizes that Tae-jun's plan is to erase the video evidence of Je-na's intimate encounter with the professor, which would expose the real killer.

The real killer of Je-na's father is revealed to be Ji-a's sister, who delivered the fatal blow to protect herself from exposure.

Jae-yi's father, the hospital director, is shown to be complicit in Tae-jun's plan, using his power to silence the truth.

Seul-gi and Jae-yi's friendship is shattered as Jae-yi's betrayal drives them into darkness.

Seul-gi is left alone, determined to fight Tae-jun and uncover the truth, even if Jae-yi is no longer with her.

The episode ends with Seul-gi standing alone, vowing to expose Tae-jun and Ji-a's sister, while Jae-yi remains trapped in her father's control.

What is the ending?

Seul-gi and Jae-yi spend the ending searching for Je-na so she can testify, but the situation turns dangerous when Tae-jun threatens Seul-gi's life. In the final turn, Jae-yi gives in to her father's demand and agrees to act like the obedient daughter he wants, while the truth they are chasing is still unresolved.

Seul-gi and Jae-yi keep moving through the episode with one clear goal: find Je-na and bring her forward as a witness. The search is not calm or simple; it carries urgency because her testimony is tied to the bigger conflict surrounding the truth.

As the pressure rises, Tae-jun steps in and threatens Seul-gi's life. This becomes the point that changes everything, because the threat is not directed at the case alone anymore, but at Seul-gi herself.

Faced with that danger, Jae-yi makes a choice. She agrees to become the obedient daughter her father wants, giving in to his control in order to protect Seul-gi.

By the end of Episode 14, Seul-gi is still caught in the struggle to expose the truth, Je-na is still being pursued so she can testify, Tae-jun remains the force applying pressure, and Jae-yi's position changes most sharply as she submits to her father's will to keep Seul-gi alive.

Is there a post-credit scene?

There is no clear evidence in the available sources that Friendly Rivalry, Season 1, Episode 14 includes a post-credit scene.

The episode descriptions from Apple TV and IMDb only summarize the main ending plot -- Seul-gi and Jae-i searching for Jae-na, and Tae-jun forcing Jae-i into obedience -- and do not mention any post-credit or mid-credit tag. The other results are social posts and reactions that discuss spoilers or cut scenes, but none explicitly confirm a post-credit scene for Episode 14.

So, based on the sources available here, the safest answer is: no confirmed post-credit scene is documented.

Why does Jae-i betray Seul-gi in Episode 14, and what is she really trying to achieve?

Jae-i and Seul-gi start the episode aligned around the same immediate goal: finding Jae-na and bringing her to court as a witness.

Is this family friendly?
