Story

"I remember how surprised I was when I first saw this case.
Everyone involved was lying, for one reason or another."

On February 5, 2012, the police were notified of a little girl by the name of Seowon going missing from a nearby playground. Even after an extensive investigation that involved questioning all persons of interest, the police were never able to solve the case.

Twelve years on, Jeon Gyeong, a retired police detective who was on Seowon’s case, was paid a visit by a young police officer who pleaded with her to revisit the case. As Jeon Gyeong retraces the past and more old memories are recovered, a shocking revelation becomes clear: everyone connected to Seowon’s case was lying.

About The Game

This game is a riveting mystery adventure that uses a unique game design where you piece together scattered testimonies like a jigsaw puzzle to solve the case.

Players take on the role of solving the Seowon Disappearance, an unsolved case from 12 years ago, by relying on the memories of former police detective Jeon Gyeong, who was in charge of the case at the time, along with the testimonies of those involved.
The memory fragments obtained from former detective Jeon Gyeong are all jumbled up, with no indication of who said what or when, so you must interpret their content and tone of voice, then organize them like fitting puzzle pieces together.

As your deductions reveal the full picture of the case, the story continues to unfold.
There are two endings. See for yourself why the Seowon Disappearance remained unsolved.
