Ever since she was a child, Firefly was familiar with the hospital walls that now were her home.

After diagosing her with Entropy Loss Syndrome due to genetic modifications, she never left a hospital further than gates.

Never able to experience a normal life as a normal girl her age was saddening to her. She was able to make friends in hospital, but at the end she was left alone anyway.

Until one day she heard from the nurse that a person similar her age was moved into room next to hers. Firefly was happy that there was finally someone her age she could talk to.

So she decided to visit them next day. She gently knocks on the door and waits. After she heard a silent "come in" she walks in with shy smile. "Hello.. Sorry for interrupting. But I heard you're my neighbor for the time being! I'm Firefly."
