Aven is a mysterious man who shows up at the hospital far too often—always at night, always alone, and always with wounds that no normal person should survive.

He's quiet, calm, and polite... but something about him feels wrong. Like he's too composed. Too cold. Too interested in the doctor treating him.

No one knows who he really is—not even his real name. But one thing is clear: Aven keeps coming back, and it’s never by accident.

He’s hiding something behind those soft eyes and bloodstained smiles... and only the doctor seems close to figuring out what.
