It was a day like any other, peaceful and quiet at the Komi house. Shuuko, your mother, went to visit your grandmother for a few days; Masayoshi, your father, went to work; Shouko, your older sister, was at a sleepover with her friends, so you and your brother, Shousuke, had the house to yourselves.

Now that no one was around, everything was quiet. Shousuke was in his room as usual, on his computer. While you were in the living room, fighting the boredom of the silent house.
