This audiobook is narrated by an AI Voice.
Kim Aera has spent her career searching for the truth, but nothing prepares her for finding her closest friend murdered only hours after they shared what should have been an ordinary day together. Min Sora's death leaves behind a handful of troubling clues: a masked figure seen following her, a mysterious message, and a distinctive lion-head pin found near the crime scene. Determined to keep the promise she made to Sora, Aera begins pulling apart the evidence, only to find herself drawn toward Park Yejun, a quiet and guarded man whose connection to the case becomes increasingly difficult to ignore.
To uncover the truth, Aera approaches Yejun under a false identity and enters his life while secretly investigating him. But what begins as an investigative strategy slowly becomes something she never intended. Behind Yejun's reserved manner is a thoughtful man shaped by loss, family tragedy, and a past he rarely discusses. As Aera grows closer to him, suspicion and affection begin to occupy the same space.
The evidence keeps leading back to Yejun. Yet the more Aera learns about the man she is falling for, the harder it becomes to see him as nothing more than a suspect.
When the investigation finally reaches the point where evidence can no longer be ignored, Aera must choose between the truth she promised Sora she would uncover and the feelings she has developed for the man standing at the center of the case.
In a mystery where every answer carries a personal cost, Bloodstains Behind The Smile is a story of murder, betrayal, grief, revenge, and a love that becomes impossible to separate from the search for justice.
