How Yuna's Route Works
Affection, trust, jealousy, and obsession decide how dangerous the story becomes.
Yuna's route is a darker romance path where every answer changes the emotional pressure. Kind replies can build affection, careless replies can trigger jealousy, and suspicious answers can push the scene into obsession.
Manage Her Obsession
Yuna watches every choice closely. Reassuring her may calm the scene, while hesitation or secrecy can make her more unstable.
Trigger Jealousy Events
Texts, missed calls, late replies, and rival characters can push Yuna into possessive reactions that change the direction of the route.
Choose Your Ending
The full route is designed around different outcomes, from romantic devotion to unstable obsession and darker consequences.
Example Scene: Suspicious Text Scene
Your phone buzzes. Yuna sees the message before you can hide it. Her expression does not change, but the room suddenly feels smaller.
"She's a coworker. We were just talking about a deadline."
Yuna pretends to believe you, but starts watching closer.
"You went through my phone?"
Yuna becomes defensive and the scene escalates.
"She's nobody. I'll block her if it bothers you."
Yuna feels reassured, but her control over you increases.
