Wishlist now and stay updated!

An Interactive Fiction Detective Adventure

“Maybe something special will happen in my life.

I used to hope for that.”

Hae-eun Shin enters Myungseo High School as a cynical realist.

Yet rumors of strange mysteries start drifting into her ears.

A roommate who suddenly vanished,

a bear roaming the schoolyard at night,

a mysterious textbook thief,

and graffiti that predicts the future—

Hae-eun scoffs; she doesn’t believe in fantasies.

But her roommates — Dahee, Serin, and Minyoung — can’t hide the spark in their eyes.

“The world isn’t that interesting!”

Will Hae-eun manage to prove how dull reality truly is?

Or will she stumble into something unexpectedly fun?

Roam through every corner of Myungseo High School and collect clues related to each mystery.

Explore new areas, talk to NPCs, and piece together the information you find.

After class, it’s time to gather in Room 502 and put your heads together.

Connect the clues to your hypotheses and build your deductions.

The more you prove your hypothesis, the closer you move toward the center of the deduction board.

Unrelated fragments and trivial details slowly converge into a single truth.

Discover the unexpected answers behind each mystery!
