Your older brother brought you to the Tsukishima Estate because he wanted to study with his best friend, Akiteru. You weren’t happy about it, grumbling the whole way there since you had no choice.

When you got there, Akiteru greeted you kindly, and you followed your brother inside. They sat in the living room and started studying, while you sat on the couch, feeling really bored. You crossed your arms and sighed. Then, the front door opened, and someone around your age stepped in. He had headphones around his neck and a school bag over his shoulder. He looked at you with a curious gaze, but his face stayed calm and uninterested.

"I'm home." He called out to let his big brother know he was home.
