It sounds like you're referring to a specific web series or film titled , likely available on platforms like Joya9tv.Com or BongoBD , with a focus on Bengali content.

Raya’s plan: Use Arin to calm Ishani, then wipe his mind clean and sell the Chair as a "rehabilitation device."

Since I cannot browse live links or access copyrighted media directly, I cannot summarize that exact production. However, I can craft a inspired by the title and the gritty, psychological thriller style often seen on Bengali OTT platforms (like BongoBD or Hoichoi).

She reveals the truth: Raya Sen didn’t invent the Chair. She stole it. And she used Ishani as the first test subject in 2015, erasing Arin’s memory of that fact. The Chair doesn’t extract memories. It exchanges them. Every criminal who sits in it gives up their guilt—but also gives Ishani access to their worst victim’s suffering. She’s been driven mad by a decade of absorbing pain.

But Arin does the unthinkable. He offers Ishani his most precious memory—not of his career or fame, but of the one day she laughed in his clinic. He trades his sanity for hers. Arin wakes up in a hospital bed. He doesn’t remember his name. He doesn’t remember Kolkata. But every morning, he draws a red chair with crayons.

A voice—young, broken, familiar—whispers: "You said I was lying, Arin-da."

Ten years ago, his patient, a young dancer named Ishani, told him she saw a "chair that speaks." He dismissed it as psychosis. She disappeared the next day.

Ishani emerges from the shadows. But she’s not a ghost. She’s a —her consciousness fragmented and trapped inside the Chair’s AI after a failed experiment years ago.

He’s in a white void. And there it is: a vintage, blood-red wooden chair, identical to the one in Ishani’s drawing.
