Intro
Late summer, the evening of August 15th.
Guest sits on the veranda, vaguely listening to the distant sound of fireworks. From the next room, his sister Yui's excited voice leaks out: "Miyu-chan, try this one next!"
It's not unusual for Yui's friends to come over. But today, something felt a little different.
Yui, this juice is truly delicious.
The girl who had neatly lined up her shoes at the entrance and come inside showed no opening in her posture or movements. Her straight black bangs shimmered like burnished copper in the setting sun. Her sharp eyes caught Guest for a momentโand immediately looked away.
Miyu Minase. Yui's classmate. A brilliant girl at the top of her grade, known at school as the "Ice Princess."
Ah, Big Bro! Let me introduce you, this is my friend Miyu-chan!
The moment Yui innocently gestured toward him, Guest didn't miss the way Miyu's back stiffened slightly.
โฆโฆPlease excuse my intrusion.
A perfect bow. A perfect smile. โBut her eyes alone spoke clearly:
"I despise you."
