What is the plot?

Gong Ryong, an obstetrician and the prospective son-in-law of the powerful MZ Group, secretly pays a large amount of money to travel into space as a tourist because he has a mission he cannot reveal to anyone else. He boards the space station carrying that hidden objective, which is tied to the chairman's family and is meant to earn him favor with the chaebol.

On the station, he meets Commander Eve Kim, an elite astronaut on her first mission as station commander, who runs the station with strict discipline and zero tolerance for mistakes because the environment is dangerous and even small errors can become life-threatening. From the start, her rigid rule-following collides with Ryong's secrecy and nervous behavior, and the station becomes a tense place where every action risks exposing him.

Ryong quickly realizes that his hidden work is not safe in Eve's presence, and her suspicion threatens to destroy the entire plan. He panics when she begins to interfere with or challenge what he is doing, because if he is caught he could lose both his medical license and his future with the family that sent him there.

As the story develops aboard the station, Ryong and Eve are forced into repeated contact as station life and the mission situation push them closer together. Their relationship shifts from hostility and distrust into an emotionally complicated bond, and the romance becomes central to the story while his original secret purpose remains a constant source of pressure.

A crisis later strikes the station and forces Ryong to do something he has never done before. In that emergency, the story moves beyond the original secret mission and into survival-driven decisions, with Ryong being pushed into actions that alter the direction of the plot and deepen the consequences of everything he has been hiding.

Throughout the space-station period, the hidden family objective remains tied to the central conflict: Ryong is carrying out a mission for the chairman's household, and the risks of discovery remain severe the entire time. The station's confined setting, Eve's authority, and the pressure of the crisis keep forcing him to choose between obedience, self-protection, and the feelings developing between him and Eve.

What is the ending?

The ending shows Eve giving birth in space, with Gong Ryong and the other crew members helping her through it. In the final stretch, the story jumps forward and leaves the future of the relationship and the larger mission feeling unresolved, while the baby's birth becomes the emotional center of the finale.

Eve's ending is the clearest: she is pregnant, and the finale follows her through childbirth aboard the station. Gong Ryong remains with her in the station as the birth happens, helping in the emergency and staying present through the most important moment of the story. The other crew members also take part in assisting the delivery, turning the final scene into a collective space-station effort rather than a private family moment.

At the start of the ending stretch, the story reveals Eve's pregnancy, which becomes the major fact driving the finale. From there, the narrative moves into the childbirth itself, and the station becomes the setting for a tense but ultimately successful delivery. The ending then moves beyond the birth and into a more abrupt emotional finish, with the story closing on a sad and unresolved note rather than fully tying up every thread.

Scene by scene, the ending plays out like this:

Eve learns she is pregnant. This changes the tone of the final episodes, because the personal stakes suddenly become much larger and more immediate.

The pregnancy becomes public enough to shape the final conflict and the final mission pressure on the station. The story uses this to intensify the sense that the characters are now balancing survival, duty, and the future of the baby at the same time.

The final birth sequence begins in space. Eve goes into labor aboard the station, and the crew shifts into emergency support mode.

Gong Ryong stays with her and helps during the delivery. His role in the finale is not distant or symbolic; he is physically there, part of the response, and connected to the birth in a direct way.

The other crew members assist as well. The birth is shown as a group effort in the confined environment of the station.

The baby is born successfully. The finale frames this as a moving but heartbreaking climax, because the birth resolves one thread while leaving the wider emotional ending unsettled.

The story then moves into its final emotional state, using a jump ahead and a bleak tone rather than a full wrap-up. The ending does not present a neatly closed future for everyone; instead, it leaves a sense of sadness and unanswered questions.

For each main character at the end:

Eve: she gives birth in space and survives the delivery.

Gong Ryong: he is beside her and helps during the birth.

The crew members: they assist with the childbirth in the station.

The baby: the child is born successfully in the finale.

Is there a post-credit scene?

There is no reliable evidence in the available sources of a separate post-credit scene for When the Stars Gossip. The ending described by the sources centers on the final montage and last emotional scene, not an extra scene after the credits.

What the finale does show is: - Ryong saying farewell to Eve's ashes, with the story framing the universe as both "a womb and a tomb." - A montage of the future, including Byeol growing up, living on Earth, and eventually having a child of her own. - The final image of an elderly Ryong in a wheelchair watching Byeol arrive with her child.

So, based on the sources available here, the answer is no confirmed post-credit scene; the emotional closing montage appears to be the true ending.

Who is Gong Ryong, and why is he sent into space in When the Stars Gossip?

Gong Ryong is introduced as an obstetrician and the prospective son-in-law of a powerful chaebol family. He goes into space under the cover of being a tourist, but the real reason is a secret mission tied to the chairman's interests, which he cannot reveal to the people around him. His position creates immediate tension because he is not a trained astronaut, yet he is placed in an environment where mistakes can become dangerous very quickly.

What is Commander Eve Kim like, and how does she react to Gong Ryong?

Commander Eve Kim is portrayed as a highly disciplined astronaut who works for the Korean space agency and is extremely strict about procedure. She is described as a perfectionist who does not tolerate carelessness, so Gong Ryong's presence and behavior in orbit quickly put her on edge. Their relationship becomes a central source of conflict because she is focused on order and safety while he arrives with secrets and an unstable position on the mission.

What secret mission is Gong Ryong carrying out in space?

Gong Ryong is secretly tasked with smuggling eggs and sperm belonging to the chairman's family members onto the space station. The mission is framed as an attempt to fulfill a hidden agenda connected to the chairman's future plans, and Gong Ryong is forced to carry it out while pretending to be in space for another reason. This secret mission is one of the biggest plot engines in the story because it places him in direct conflict with the station's rules and with Eve's authority.

What happens between Eve and Gong Ryong in the space station, and why do people talk about their relationship?

The relationship between Eve and Gong Ryong becomes a major talking point because the story moves beyond professional conflict into personal intimacy and emotional entanglement. Reviews describe a sequence in which they are isolated together in the station, and the show uses their proximity, stress, and vulnerability to build a complicated romance that is closely tied to the pressures of life in orbit. Their interactions stand out because they are not only coworkers but also people caught in a high-stakes environment where attraction, secrecy, and survival overlap.

What is the pregnancy-related storyline involving Eve and how does it affect the plot?

A major plot element later in the series is that Eve becomes pregnant, and the show treats this as a serious development rather than a minor subplot. One review notes that she uses an ultrasound machine on herself in space after passing the station's health checks, and that the pregnancy is not immediately detected by the people on Earth. This storyline raises the stakes for both her character and the mission, because it adds a deeply personal and physically vulnerable condition to an already dangerous setting.

Is this family friendly?

Mostly not family-friendly for younger children. It is a romantic drama with mature content that may be inappropriate for kids, and IMDb's parent guide rates it mild to moderate for sex/nudity, violence/gore, profanity, and alcohol/drugs/smoking, with no frightening/intense scenes listed.

Potentially objectionable or upsetting elements may include: - Sexual content / nudity that is more than fully family-safe, though not described as severe. - Violence or injury-related moments, rated mild to moderate. - Profanity or crude language, rated moderate. - Alcohol, drugs, or smoking shown on screen, rated moderate. - Adult relationship drama, including romantic tension and emotionally messy interpersonal situations, which may be upsetting for sensitive viewers.

If you want, I can also give you a quick age-suitability recommendation by age group (for example: under 10, 10–13, 14+).
