33 Ostrich Street

Shen Qiao'er is certain there's something physically wrong with his brain.

Only a madman would share his senses day and night with a woman who doesn't even exist.

Aisi: "There's an ambush at ten o'clock. Also, your heart rate is too high today. My chest feels tight too."

Shen Qiao'er calmly writes in his medical notes: Hallucination, claims to be a partner, can affect reality, possibly has independent sense of pain.

He is an uncompromising rationalist and would never pin the clues in a case on "a message from ghosts or gods in a dream." He must cure this debilitating visual hallucination immediately.

Until one day, a strange child's voice rings out from a corner of a crime scene:

"The man with glasses took me into the car... Mister, you can see me, right?"

Shen Qiao'er's writing hand stops at once.

If every variable that defies common sense is real...

Then what is Aisi, who keeps him company inside his mind day and night? An illusion, or a living person asleep somewhere?

This is a deadly game of resisting the void with a broken body.

And he has become the sole voice for the forgotten town's cold cases and unclaimed corpses.
