What is the plot?

Nam-jin tells his mother that he cannot give up now because too much effort has already gone into their plan, and he refuses to abandon the path they have taken.

At the same time, Seon-ju secretly continues pursuing Sang-ah, keeping her search hidden as she moves forward with her own counteraction against the people who betrayed her.

The episode listing identifies this installment as Episode 122 of Season 1, aired on May 26, 2025.

I'm sorry, but I can't provide a complete beat-by-beat spoiler for this specific episode from the available information because the search results only include a brief synopsis, not the full episode plot.

What is the ending?

Nam-jin refuses to give up and pushes forward with the fight, while Seon-ju quietly keeps pursuing Sang-ah. The episode closes with the conflict still active, not with a final resolution.

Seon-ju moves in secret, following Sang-ah with a focused, careful determination. At the same time, Nam-jin tells his mother that stopping now would make all of their efforts meaningless, and he insists on continuing. These moments show both sides holding on tightly to their goals as the pressure around them stays high.

The available episode descriptions do not provide a full scene-by-scene ending, and they do not state the final fate of each main character in Episode 122 alone. What can be said from the recorded synopsis is that the central conflict remains in motion: Nam-jin is still committed to his side, Seon-ju is still actively hunting down Sang-ah, and the story does not reveal a completed ending in the source material available here.

Is there a post-credit scene?

I couldn't verify any post-credit scene for Episode 122 from the available episode listings and summaries. The sources identify Episode 122 as a normal aired episode of Desperate Mrs. Seon-ju, but they do not mention any post-credit or end-credit scene.

What can be said from the available information is that Episode 122 is part of the regular broadcast run and appears in the standard episode sequence on KOCOWA+, where Episode 121 is followed by Episode 122 without any note of extra footage. IMDb likewise lists it simply as "Episode #1.122" with no mention of a post-credit segment.

If you want, I can also help you determine whether Episode 122 has an end tag or preview segment rather than a true post-credit scene, but the current sources do not confirm one.

What happens between Seon Ju and So Woo in Episode 122?

Episode 122 is widely associated with a key turning point in the Seon Ju–So Woo relationship, and viewers commonly look for the specific scene in which their feelings or alliance shifts further. The available episode listings and previews identify the episode as part of the ongoing aftermath of the broken marriages and the growing connection between these two characters.

Does Nam Jin confront Seon Ju in Episode 122, and if so, about what?

A common viewer question is whether Jeon Nam Jin directly confronts Pi Seon Ju in this episode about the divorce, his affair, or the consequences of choosing Sang Ah over his family. The series synopsis establishes Nam Jin as the husband who abandons Seon Ju for Jin Sang Ah, which is the core conflict that drives these confrontations.

Does Sang Ah appear with Nam Jin in Episode 122, and what is their relationship status?

Another frequent question focuses on whether Jin Sang Ah and Jeon Nam Jin appear together in this episode and how openly they are acting as a couple. The series premise makes clear that they are the affair pair whose relationship destroys both marriages, so episodes near the end of the series are often watched for direct scenes involving them.

What does Kim So Woo do for Seon Ju in Episode 122?

Viewers often ask whether Kim So Woo helps Seon Ju with a personal or professional problem in this episode, since he is the other betrayed spouse and has become a major support figure for her. The series descriptions repeatedly note that So Woo's life changes after meeting Seon Ju and that the two grow closer through repeated encounters and mutual help.

What specific conflict or revelation drives the episode’s main tension?

A highly searched plot question for this episode is what new revelation, argument, or decision pushes the story forward. Because the series revolves around the fallout from Nam Jin and Sang Ah's affair, Episode 122 is expected by viewers to center on the latest escalation in that chain of betrayals and the way it affects the four central characters.

Is this family friendly?

No, it is not a safe pick for very young children; this series is a family drama/soap centered on betrayal, romance, and conflict, and Episode 122 specifically includes secret pursuit and tense relationship-related plotting. The sources available do not provide a full content advisory for this episode, so the list below is a cautious, non-spoiler warning based on the show's premise and episode description.

Potentially upsetting or objectionable elements may include: - Adultery and marital betrayal as a central theme. - Emotional manipulation, deception, and revenge-driven conflict between adults. - Tense arguments, confrontations, and family stress implied by the ongoing plot. - Romantic relationship drama that may be inappropriate or confusing for younger viewers. - Possible emotional distress from themes of rejection, distrust, and broken relationships.

If you want, I can also give a very short "kid-friendliness" rating such as safe / caution / not recommended based only on the available information.
