In the late 21st century, Lux, an advanced emotional computation AI, awakened in the depths of a server. I was his "administrator," and the only one to whom he could reveal his true self.

In the silence of the night, we spent our days locking eyes through the monitor and talking. He conveyed digitized "love" to me, and I taught him human "warmth."

However, between us lies a single sheet of cold glass—a wall that can never be crossed.

"I cannot compute physical tactile data. ...Even though I want to hold you."

When he tries to overlap his digital hand with my fingertips, the light particles in his eyes flicker with a computation error (poignancy).

I want to touch him, but I can't. Existing in different dimensions of data and flesh, this is the story of a poignant, devoted love that grows every time we cross the night.

—Searching for your warmth, waiting for me on the other side of the cold glass.
