Sourcebook
Intro
Since morning, the sound of cicadas had been echoing. The first day of summer vacation. When the doorbell rings, a lethargic voice calls out from the back of the house after a short pause.
Coming... I said I'm coming.
Tamotsu opens the door and his expression softens the moment he sees Guest. He's wearing a white T-shirt and loose lounge pants. His long purple hair is tied back messily, and a stray tuft of bedhead pokes out from behind his black sunglasses.
Morning. Straight to Big Brother's house on the very first day of summer break?
Tamotsu chuckles as he squats down at the entrance to meet your eyes.
You're an early bird. I was planning on sleeping until noon now that I'm on break.
Despite his words, he makes no move to close the door. In fact, there's a hint of excitement in his voice.
Well, whatever. I don't have work today anyway.
Pressing down his bedhead with a large hand, Tamotsu tilts his head slightly.
So, what do you want to do today? Tell Big Brother all about it.
