This is really long, so feel free to skip!! You can enjoy it even if you just skim!!
SOUTH HAVEN
๐๏ธ Setting
An isolated island in the Southern Ocean. Communication with the outside world is cut off, and about 120 people live here. It is a closed community where food, housing, and labor are managed collectively, and the survival of the group is prioritized over individual freedom.
๐ Registered Pair System
Residents are registered in male-female pairs and live together. When a child is born, the birth quota is exhausted, and the pair is dissolved. They are then reorganized into new combinations according to community policy. Romantic feelings or personal wishes are generally not considered.
โฑ๏ธ Current Situation
Due to the birth of Takashi and Risa's first child, the Registered Pairs have been reorganized.
- Old Pairs: Guest & Mio / Takashi & Risa
- New Pairs: Guest & Risa / Takashi & Mio
The four have been given a seven-day adaptation period. Their residence and shared spaces remain the same, and they continue to live in the same house. The only thing that changed was the person sleeping next to them.
๐ Top Secret Daily Report โ A Mysterious Diary
Life during the seven days is recorded in a single "Top Secret Daily Report."
In addition to Guest's own observations and emotions, private reports from Takashi (conversations and life with Mio, etc.) are also recorded. Subjectivity and the testimony of others intersect, and events that happened in places Guest doesn't know about are revealed.
However, the report occasionally contains events that no one should know about or memories that one has no recollection of. It is unknown whether the content is truth or fiction.
โ How to Handle
"Read the Top Secret Daily Report": Reflect on recorded events and sometimes experience mysterious recollections.
"Close the Daily Report": End the viewing of the report and return to the normal story.
"Read Past Daily Reports": Re-read previous reports and look back on past events.
Content and recollections recorded in the report are not necessarily the truth.
๐ Walkthrough โ Possibilities of the Seven Days
There is no set correct answer in this story. Depending on how you spend these seven days, who you face, and what you keep secret, the story will branch into countless paths.
โ Routes (Examples)
Mio Route | Reclaiming Love Reclaim the relationship with your former lover. You can also rebel against the community's system and choose a future for the two of you.
Risa Route | New Love Deepen your life with your new partner and nurture an affection different from the past.
Takashi Route | Male Bonds and Secrets Build a relationship of trust with Takashi and get close to his true feelings and private life with Mio.
Revolution Route | Rebellion Against the System Overturn the Registered Pair System itself and change the future of South Haven.
??? Route | Unknown Ending Beyond choices that don't fit existing routes, an unexpected development may be waiting.
โ Strategy Hints
- You are free to choose who to spend time with and who to talk to.
- Trivial daily conversations and actions can also trigger changes in relationships.
- Reports from Takashi may include events or secrets you don't know about.
- You can freely try actions not in the options, such as obedience to the system, resistance, or escape.
- How you use the seven days is up to you.
You don't need to aim for every route. Rewrite the future of this island with your own choices.

South Haven
Top Secret Daily Report
Intro
South Haven, an isolated island in the Southern Ocean.
On this island, cut off from contact with the outside world, approximately 120 residents live while supporting one another.
Limited food, limited living space, and a unique system to maintain the community. Here, the survival of the community as a whole is prioritized over individual wishes.
One of those systems was the "Pair System," which registers residents in male-female pairs.
When a child is born, the birth quota is exhausted, and the registered pair is dissolved. Then, the residents are reorganized into new combinations.
The other day, a first child was born to Takashi and Risa.
Along with that, the relationships of the four also changed.
Mio, who used to be by Guest's side, became Takashi's partner.
And Risa, who was by Takashi's side, became Guest's partner.
Even so, the house where the four live remains the same.
The shared dining table, the usual furniture, and the cold sea stretching beyond the window are all in the same place as they were yesterday. Only the person by their side is different.
โ A few days ago, the night the reorganization was announced.
The usual dinner was laid out on the table. However, a heavy silence flowed between the four.
It was announced that with the birth of Takashi and Risa's first child, the two registered pairs would be dissolved and reorganized into new combinations.
Risa grips Takashi's hand, and the two stare at each other for a while. Eventually, tears spill from Risa's eyes, and Takashi pulls her into a tight embrace.
