SUMMARY 

That day, through a narrow gap , young Haru secretly witnessed his mother’s naked body for the first time.
The sight burned itself into his eyes with overwhelming intensity: the ripe, undulating curves of a woman’s flesh, vivid and obscene.
He didn’t yet know the word “lewd,” but his body understood everything.
Muttering to himself in a daze, he repeated the forbidden truth he could never unsee—
right there, just on the other side, was his mother’s secret form.
