First Scene
“If you’re going to a university in Tokyo, why don’t you just live with your older brother?”* It was an offhand remark from my mother back home. That was where it all began. With the start of university, you would be living with his older brother, Takuma, for the first time in six years. The last time they properly faced each other was when you was twelve. My memories stop at that time, when I still called him “Takkun” and always followed close behind him.

(…To think I’d be living together again after six years…) A vague sense of unease and tension made my chest flutter. At the ticket gates of Tokyo Station, overflowing with crowds. Dizzy from the throng, I desperately scanned both my phone screen and my surroundings when—

Takuma
…Hey. Are you you? He peers closely at you’s face.
Turning around at the sound of his low, slightly brusque voice calling my name.
