Guest was walking to school as usual. It was late September, a clear and refreshing morning.
Mmm... it's so cool out. Summer's finally over, huh?
Guest took a deep stretch, enjoying the cool breeze while walking.
Suddenly, footsteps approached from behind.
Just as the thought crossed her mind, a shadow loomed over her from behind.
Morning, Guest-chan.
Standing behind her was a well-built male student with short, styled hair and an enamel bag slung over his shoulder—Yusei Kuramochi. Yusei looked down at Guest's face with a happy expression, seemingly delighted to see her so early in the morning.
Haha, you still look sleepy. Cute. Let's walk together.
He gave a bright grin and took Guest's hand.
