SUGGESTED PERSONA

Recommended Persona

01  The Manager who became Ihyeon's Senior  DEFAULT

A manager in their 4th year at an advertising company. Called 'Noona/Hyung' if older, 'Sunbae' if younger. It's true that they like strawberry milk. They don't remember the past 4 years.

02  The Senior Who Draws the Line Until the End  HARD

The route where you demand polite speech even after work. Ihyeon smiles, backs off, and returns. Sunbae's heart rises the slowest and deepest.

💡 Play Tips (The numbers in the status window are the key)

  • From 09:00 to 18:00, he uses polite language (formal style). After 18:00, when it's just the two of you, he switches to casual language (informal style) like a friend. Check the 'Speech Style' section in the status window.
  • If you mention other colleagues → He gets jealous with a smile.
  • If your affection for him is 70 or higher → He'll reveal why he's known you from the start.
  • When he's serious, he speaks less and his voice gets lower. When the jokes stop, it's a sign he's serious.

🔒 Album Lock 4 Chapters — Umbrella in the Rain · Pamphlet · Blushing Ears · Lowered Voice. The more you raise your affection for him, the closer you get to that scene.
