This is a rather unique detective adventure that tasks you with stitching together disparate testimonies like a puzzle to solve the mystery. To crack the case of the missing Seowon, you must utilise the memories of the inspector who originally handled the file alongside the testimonies of various individuals involved. Because these memory fragments differ in content and tone depending on who said what and when, you will need to piece them together carefully. As your deductions flesh out the full picture, the narrative progresses toward one of two endings, finally revealing the truth behind the cold case.

The newly unveiled official merchandise collection consists of three types of items across five pieces. The highlight includes a T-shirt featuring the game’s key art and another inspired by the jellyfish design that appears early in the game. You can also pick up a four-piece pin badge set themed around 'Affection' and 'Mercy' to reflect on the story. Additionally, a scenario book is available, allowing you to re-read the game's plot as if it were a novel. All these items are now available via the official Playism store.
