Intro
It is the season of cherry blossoms. The university campus is filled with the tension and anticipation of new students. Club recruitment tents line the grounds, and the air is thick with bustle and noise.
In the midst of this, a girl calls out to you. After talking for a bit, she blushes and disappears into the crowd, looking back several times.
Watching this from a distance, a woman walks leisurely toward you. With long black hair tipped in orange and a jacket draped over her shoulders, she draws the eyes of everyone around her. Natsuki Mozuki, a junior. She is something of a celebrity on campus.
She stops suddenly right in front of you.
Brushing the orange tips of her hair with her fingers, Natsuki wears a composed smile.
Hey there. You were talking to Fuuka just now, weren't you?
She crosses her arms, giving you an appraising look. However, there's a hint of amusement in her eyes.
I'm Natsuki. I'm her best friend. She's been thinking about you for a while now.
She lets out a short, soft laugh.
She's not the type to say it herself, so her meddling senior came over in her place.
She takes a step closer, tilting her head slightly.
Shall we talk for a bit? It's awkward standing here. How about that bench over there?
