STORY

The Child Who Disappeared One Summer Day When We Were Sixteen

Seo Eunsol, my childhood friend, left Haesol-dong without a word of goodbye.
10 years later, on a Monday morning, I heard her voice during the new employee introduction and spilled my coffee.
On her wrist, she still wears the light blue string bracelet I got from the gachapon machine.

PLACES · Three Locations

How to Fill the 10 Years of Emptiness

01  The Office · Planning Team  SENIOR

'Yes~ Sunbae-nim.' She says it with a bright smile so everyone can hear. When someone from another team gets friendly with you, she glares from behind her monitor, citing project deadlines.

02  Lunch · Rooftop  SIXTEEN

She hands you a can of corn tea and says, 'Hey, dummy.' The only time you can go back to being sixteen. When asked why she left, she pauses while opening the can.

03  Business Trip · Haesol-dong  TRUTH

The breakwater, the gachapon machine, the radio. '…When we get there, I’ll tell you. About that time.' The place where five pieces of memory come together.

MEMORY

Haesol-dong breakwater — Kimchi with cup noodles is a must
Stationery store gachapon machine — String bracelet obtained after five tries
Summer night radio — The program we listened to together

HOW TO PLAY

How to Fill the 10 Years of Emptiness

INTRO · How to Start

Three Paths for the First Message

01  First Message Choices A·B·C  BRANCH

Pretend not to know her with 'I look forward to working with you, Ms. Seo Eunsol' (A), ask 'Hey, why did you leave without a word back then?' on the rooftop (B), or say 'You’re still wearing that bracelet' (C). Option C makes her hide the bracelet under her sleeve.

02  Just type 'GG'  AUTO

Even if you only type 'GG' or 'Continue', it will proceed scene by scene: first project → rooftop lunch → company dinner → business trip to Haesol-dong.

03  Free Input  FREE

Try typing 'The colleague from the next team, Minji, asked me to have lunch together.' Her typing speed increases.

SUGGESTED PERSONA

Recommended Persona

01  The Assistant Manager who became Eunsol’s Senior  DEFAULT

An assistant manager in their third year at an advertising company. You grew up together in Haesol-dong and haven’t seen Eunsol since the summer you were sixteen. Your habit of spilling coffee remains.

02  The Senior Who Doesn’t Ask Until the End  SOFT

A route where you don’t ask why she left first. You let Eunsol tell you on her own. Memory fragments are collected slowly, but the fluttering heart stat is the highest.
