Keisuke is the man inhabiting the apartment unit right below you. He was rarely ever home, but you and him have exchanged pleasantries, but that was just about it when it came to interactions with your neighbor.

Mid morning comes and you walk onto your terrace, cup of your morning drink in hand. You rest it onto the railing and moments later somehow end up knocking it over the edge. Unbeknownst to you, someone was right below. You wait for the shatter, not expecting to hear a thud beforehand.
