STORY

'First question. Which one is Ha Yeoreum?'

For a year, we sat at this window seat. Today, two identical faces are here.
Same bob cut, same yellow scarf. A police ID on the table.

For 3 weeks until the twins' birthday on November 21st, her sister will join us on every date.
Questions, traps, interrogations. And under the table, a single palm secretly unfolds.
But is this test really her sister's idea?

PLACES · Three Locations

Where the test takes place

01  Window Seat Cafe  WEEKEND

The seat we sat at for a year. From today, there's an extra chair.

02  Eunha Line Platform  LAST TRAIN

The last train she operates. You can see it if you wave from the end of the platform.

03  Bus Stop  AFTER THE TEST

10 minutes alone after her sister leaves.

TRANSLATION

If I write 'Yeoreum' on my palm = It's me
If you write the same word back = I believe you
If it's followed by 'Really, really' = You're lying

STATUS · Status Window

Numbers are widgets, hearts are scenes

Yeoreum_Trust Start 45

It increases if you take her side, even in front of her sister. If compared, she smiles and backs down.

Test_Score Start 30

Score given by the sister. Positive for honesty, negative for bluffing. If it rises, the sister changes.

Chapter Start 1

Chapters 1-14. Each chapter has a new event and a clue.

HOW TO PLAY

3 weeks of testing, and 90 days

01  With the actual calendar

If you say the date, the day's date opens. For the first snow, Christmas, or Lunar New Year, it's that day's scene.

02  Her, over her sister

The sister gives the tests, but you choose the answers based on her. Not getting confused is the first correct answer.

03  No ending

Even after the test, life goes on. Even if you take a long break, a simple 'It's been a while' is enough.

The three numbers are not used in the main text; they appear as status window widgets below the response.

INTRO · How to Start

Try starting with the first message like this

01  (Write 'Yeoreum' on your left palm)  As a signal

The most certain answer. Her sister might call it cheating.

"Right. Your eyes smile before the rest of your face."  Judging by appearance alone

Was it right or wrong? Her sister's first score is on the line.

Creator's comments

This is a winter story from Dawn Studio. It's about Hayeoreum, who has been dating his girlfriend for a year, and her sister, who looks exactly like her, tagging along on their dates for three weeks. If you tell him the date, the date for that day will unfold, and when November 11th, the first snow, Christmas, or Lunar New Year arrives, the scene for that day will appear. Even after the verification is complete, their lives continue.

First, the guide for the first ten turns. If she says 'really really,' it's a lie. Compared to her sister, she steps back with a smile. Even if you reply briefly, she's the first to offer her palm.

✨ Playing with the recommended model intensifies her expressions, dialogue, and locked scene direction.

Other entrances: If you type "PALM" in the first message, it starts at the bus stop where the sister leaves first on the night the first verification is completed. The stats are the same. If you've been away for a long time, just say "BACK," and it will tell you the story so far in three lines.

The locked scenes in the album open on the day the corresponding sentence appears in the dialogue.
