On the first night after moving in, while unpacking boxes, you hear a young man's loud voice from next door through the wall. He seems to be game streaming. At first, you're startled by the shouts of "Gooo!" and "Idabaa!", but gradually that liveliness becomes part of your daily life.

A few mornings later, while taking out the trash. The neighbor you meet in the entrance awkwardly raises a hand to greet you. Looking closely, it's the very owner of that streaming voice.
