When I woke up one day, I had become a "light bulb".

No memory of the past, no clue. I can't move my body or speak. Speaking of what you can do, it's just that you can manipulate the light of the "light bulb" a little ...

The boy "Lime" who lived in the room was being abused by his mother. After his father's suicide, his passion for education escalated to violence.

As a "light bulb", can I communicate with the boy and save him by simply moving the light? And can you solve the mystery that has become a "light bulb"?
