What is the plot?

Myung-ha is shaken after the system gives him a new choice: he can end the game after 14 days, or he can send everything back 100 days, but Yeon-woo's affection level will be reset to 0. He makes the decision quickly and without hesitation, choosing to continue by going back, even though the price is losing all the progress he has made with Yeon-woo.

Before that choice appears, Yeon-woo is already gone, and Myung-ha is left facing the system error by himself. The situation is worsened by another system error warning that the server is severely damaged, making the whole game world feel unstable and on the verge of collapse.

The emotional center of the episode is Myung-ha's panic at losing Yeon-woo. The recap describes that when Myung-ha's world starts literally falling apart, what he wants is Yeon-woo, and that his breakup was something he believed he was doing for Yeon-woo's sake, even though his frightened reaction revealed what he truly wanted.

The episode then frames Myung-ha's decision as part of a larger crisis already building around him. At this point, the story has already established that Myung-ha has not yet chosen between sacrificing his grandmother or his boyfriend, which shows the emotional trap he is in before the episode's choice is forced on him.

What is the ending?

Myung-ha reaches the point where he must choose between losing Yeo-woon or giving up the time he has left, and he chooses to stay with Yeo-woon, even though that means facing the end of his own path. At the end of the episode, the world around him begins to break apart, and he calls for Yeo-woon as everything starts to collapse.

Myung-ha is alone after Yeo-woon leaves, and the system gives him a new choice: end after 14 days, or go back 100 days but reset Yeo-woon's affection to zero. He chooses to end rather than lose what he has built with Yeo-woon. The system then glitches again, the server is badly damaged, and Myung-ha is sent back to his room while being erased. As the school falls apart around him, he runs to find Yeo-woon, calls him, and asks him to meet on the roof. Yeo-woon runs toward him, but Myung-ha reaches the roof first and finds that the stairs are gone and a hole is opening in the sky. The Love Supremacy Zone closes in, and a notice says the cause of the error is being deleted. Myung-ha keeps calling Yeo-woon's name, but he cannot reach him.

In the broader ending of the story, Myung-ha is revealed to have already died in the real world before entering the simulation, and when he is erased from the game, his presence is gone from that world too. Yeo-woon, however, does not simply forget him at once; he continues living with lingering traces of Myung-ha in his mind, and those traces eventually lead him back toward the truth of what happened. The final movement of the story centers on Yeon-woo finding the means to enter the simulation and search for Myung-ha, with the two eventually meeting again and embracing at the beach.

Is there a post-credit scene?

Yes. Episode 7, "Choose," does include a post-credit scene.

In that scene, the story briefly returns to the emotional state left by the episode's ending: after Myungha makes his choice to continue forward with Yeo-woon rather than ending the game early, the post-credit moment serves as a quiet tease of what that decision means for their relationship. The scene is short and subdued rather than dramatic, functioning more as a final emotional button than a plot twist.

The available episode recap confirms the central choice in the episode--Myungha is given the option to end after 14 days or go back 100 days, which would reset Yeo-woon's affection to 0, and he chooses quickly. A separate discussion of the series' ending also reinforces that the show uses small extra moments to underline the emotional stakes and the connection between the two leads.

If you want, I can also describe the full episode 7 ending beat-by-beat.

Why does Myungha have to choose between ending the game soon or going back 100 days, and why does Yeo-woon’s affection reset to 0 if he goes back?

In episode 7, Myungha is given a new game choice with two clear consequences: he can finish after 14 days, or he can return 100 days earlier, but Yeo-woon's affection level will be reset to zero. The question matters because Myungha makes this decision quickly, showing how important Yeo-woon has become to him and how seriously he takes the bond they have built inside the simulation.

What exactly happens to Yeo-woon’s relationship progress with Myungha in episode 7, and why is that so important to the story?

Episode 7 centers on the idea that Yeo-woon's affection is not permanent progress but something the game can erase. That reset creates a strong emotional stakes shift, because Myungha is no longer just trying to complete missions; he is facing the possibility of losing the emotional trust he has already earned with Yeo-woon.

How does Myungha react when he is forced to decide whether to leave soon or rewind time, and what does that reveal about his feelings for Yeo-woon?

According to the episode 7 recap, Myungha chooses almost immediately, which suggests he is not treating the decision as a detached strategy problem. His fast response implies that Yeo-woon's feelings matter to him enough that he is willing to take a major risk rather than simply preserve the easiest route forward.

What is the significance of the ‘100 days back’ option in episode 7, and what would Myungha lose by taking it?

The 100-days-back option would give Myungha more time, but it comes with the cost of resetting Yeo-woon's affection to zero. That means he would lose all relationship progress and have to rebuild trust and closeness from the beginning, which makes the choice emotionally and strategically costly.

Which specific character relationship is most affected by the big choice in episode 7, Myungha’s bond with Yeo-woon or with the other supporting characters?

The episode 7 choice is specifically tied to Myungha's bond with Yeo-woon, not the broader ensemble. The recap frames the decision entirely around whether Myungha values finishing soon or preserving the connection he has formed with Yeo-woon, making that relationship the central focus of the episode's plot tension.

Is this family friendly?

It is not especially family friendly for young children, but it is also not known for heavy graphic content. The available parental guide for the series rates sex and nudity as none, violence and gore as mild, profanity as none, alcohol/drugs/smoking as mild, and frightening/intense scenes as none; the series also carries a 15 certification in South Korea.

Potentially objectionable or upsetting elements for children or sensitive viewers may include: - Mild violence or injury-related moments. - Mild alcohol, drugs, or smoking-related content. - Emotional intensity from the romantic/dramatic storyline, even though IMDb does not flag frightening scenes for the series overall.

For episode 7 specifically, publicly available episode information is limited, so I can only say that it is part of the same series and there is no evidence in the available guide of explicit sex, strong profanity, or severe violence.
