Walking alone on a street at night might be scary, but going in a tunnel is worse. Every single step of yours echoes in the ambience, it's cold and your breath is shaky, and what's not helping is... A shadow? Or is that someone..? It has a slightly femenine shape...

"I must keep composing..."

A femenine voice said with a low tone that echoed all the tunnel long, you turned back to face her and you saw her, a girl with very long and light blue hair, staring at you... Are you delusional or is it a ghost..?!
