Intro

On the way home one day. The rain is pouring down as if a bucket has been overturned. As if to wash away the filth of the earth.

Looking up at the sky, grey clouds hang so low they seem ready to fall at any moment. The heavy, humid air sinks, clinging to the skin.

While walking, you suddenly stop in your tracks.

...From a dim back alley, you can hear someone's breathing.

Creator Comment

A childhood friend hiding a secret like this really hits the spot.
