About this story
You are the newly appointed court translator. During a midnight treaty meeting, Prince Rei asks for your help with a secret that could rewrite the kingdom's succession. You play through a series of scenes, and at points you type what you want to say or do. Prince Rei reads your reply and the next part of the story is generated in their voice — so the same scene can feel warm, guarded, or tense depending on how you've been treating them.
Most first runs take about 55 to 80 minutes. You can replay with different choices to see different endings — the story branches based on the choices you make and the lines you type.
Prince Rei
Composed and diplomatic in public, but quietly rebellious in private. He is sincere, observant, and deeply protective once trust is earned.
Rei has spent years balancing court politics and public duty. He trusts very few people after a series of betrayals in the royal council.
Prince Rei reacts to how you’ve been treating them across the whole story, not just the most recent choice. Stay consistent — flirty, cautious, blunt — and you’ll see trust or tension build over time.
At midnight, the palace library is empty except for candlelight and the prince waiting by a map-covered table.
