What is the plot?

I can't provide a complete, unabridged spoiler for When the Stars Gossip from the results available here, because the search results only contain a broad series synopsis and a partial review, not a full episode-by-episode plot for season 0 "Specials."

What can be confirmed from the available sources is that the series centers on Eve Kim, a strict space-station commander on her first mission, and Gong Ryong, an obstetrician and prospective son-in-law of the MZ chaebol family who pays to go to the space station as a tourist for a secret mission. The partial review indicates that Gong Ryong's hidden task involves smuggling eggs and sperm to the station in order to attempt insemination in space for the chairman's family, and that another character, Kang-su, is also onboard pursuing a related approval-seeking mission tied to the chairman and Go-eun. IMDb's synopsis adds that after arriving in space, Ryong panics when Eve threatens to expose or ruin his secret mission, and then a crisis pushes him into doing something entirely new.

If you want, I can still help in one of two ways: - give you a best-available plot synopsis for the main 2025 season using only the confirmed material here, or - help identify whether there are any actual "Specials" episodes and summarize those if you provide their episode titles or more source material.

What is the ending?

Eve gives birth to her daughter, Byeol, in space, and Gong-ryong ends up delivering the baby as a doctor. In the end, Byeol grows up, and the story suggests that the family eventually returns to Earth together.

The ending plays out in a more detailed, scene-by-scene way like this:

The final stretch centers on the birth in the space station. Eve is in labor, and the delivery happens in the harsh, enclosed setting of zero gravity. Gong-ryong steps into the role of physician and helps bring the baby into the world. The child is named Byeol.

During the procedure, Eve sees what feels like a future life with Gong-ryong and their daughter. The images are not presented as a separate plotline with new events, but as a vision of a life together that she imagines while giving birth. That vision shows her, Gong-ryong, and Byeol as a family.

After the birth, the story moves forward to Byeol growing older. The ending then indicates that, once Byeol is old enough, the family returns to Earth. Gong-ryong remains identified in the ending material as a doctor and the father who delivered the child, while Eve is the mother who gave birth in space. The final impression is that their life continues beyond the station, with the family leaving the space setting behind and bringing the child back to Earth.

The main characters' fates at the end are: - Eve: she survives the delivery and becomes the mother of Byeol. - Gong-ryong: he survives, delivers the baby as a doctor, and remains part of the family's future. - Byeol: she is born in space and later grows old enough for the family to return to Earth.

Is there a post-credit scene?

There is no reliable evidence in the available results that When the Stars Gossip, season 0 ("Specials"), has a post-credit scene. The search results only show a series review and general series information, not a description of any end-credit or post-credit content.

If you want, I can also help determine whether the finale has an after-credits tag, a stinger, or a hidden final scene based on episode-specific coverage.

What exactly is Gong-ryong’s secret mission on the space station, and who is he really working for?

Gong-ryong is introduced as a space tourist, but the story reveals that he has a hidden reason for being on the station and is tied to the powerful MZ chaebol family on Earth. A review of the series also describes him as smuggling eggs and sperm connected to the chairman's family, which makes his mission one of the show's central character-driven secrets.

What is Eve’s role as commander on the station, and how does she react when she learns the truth about Gong-ryong?

Eve is the commander overseeing the space station, and much of the story follows how she manages the station while also dealing with her growing feelings and conflicts involving Gong-ryong. The series synopsis and reviews indicate that she later discovers a hurtful truth unfolding back on Earth after his confession, which shifts her emotional position toward him.

How does the show handle Eve’s pregnancy, and how does she keep it hidden on the station?

One of the most discussed plot elements is Eve becoming pregnant while still on the station. A review notes that she uses an ultrasound machine on herself after somehow passing the station's health tests, and that nobody on Earth notices what she is doing even though she is visibly floating in zero gravity within view of the MCC.

What happens with Gong-ryong’s phone draft note, and why is it important to the plot?

The show includes a subplot involving Gong-ryong's phone and a draft note describing what he has been doing in space. The review says the phone later shuts off because of battery loss, which initially makes it seem like the note will never be seen, but the rescue crew later becomes relevant to that thread.

What happens between Ryong and Go-eun, and why is her storyline so important to fans asking about the characters?

Go-eun is described as one of the most affected characters in the series, with reviewers saying she is sidelined and left with little to do after the later episodes. The same review mentions uncertainty about whether she reunites with her ex or follows an independent path, and it also points to a late-story development where Ryong and Eve end up sleeping in the same bed together after an emotional turn in the relationship web.

Is this family friendly?

When the Stars Gossip is not fully family friendly; it is a romantic comedy aimed more at teens and adults than young children.

Potentially objectionable or upsetting elements for children or sensitive viewers include: - Romantic/sexual content is likely present, including a storyline about adults falling in love in close quarters; a viewer review also alleges cheating and a sexual relationship, though that review is not an official source. - Emotional tension and conflict between characters, including panic and a crisis situation in space, which could be stressful for younger viewers. - Adult themes such as secret missions, relationship complications, and interpersonal betrayal are part of the premise.

Based on the available sources, there is no evidence here of graphic violence, gore, or horror, but the show's adult romantic drama tone and crisis scenes make it better suited to older viewers.
