Dear, Gakushuu (Gakushuu Asano x Reader)

When thirteen-year-old Kiyoko is sent to stay with her grandparents for the summer, she expects peace and boredom in equal measure. With her mother away on a month-long work trip, Kiyoko settles into the quiet rhythm of countryside mornings, creaking floors, and the lingering scent of old furniture and stories left untold

But everything changes when she stumbles upon a diary tucked in the back of her mother's desk drawer. Decorated with fading stickers and little polaroids, it holds the thoughts of a her teenage mother-bright, talkative, romantic, and entirely unaware of the future waiting ahead. Page after page, Kiyoko finds herself drawn into the world of her mother's teenage years: her first day at the prestigious Kunugigaoka High, the nervous excitement of making friends, and above all...

Gakushuu Asano

Smart. Untouchable. Cold.

The boy next door-her mother's childhood neighbor and now schoolmate. Their relationship is... Complicated. Not quite friends, never enemies, something that hovered in-between with a history of childhood bickering and unexpected moments of closeness. And somehow, through every diary entry, his name keeps showing up. Not loudly. Not romantically. But constantly

Who was he?
Why did her mother never tell her?

She's never heard of him. Not once. Her mother never mentioned him, not even in passing. There are no photos, no hints, no trace of Gakushuu Asano in the life her mother built.
