After more than a decade apart, sister Dalia returns home to find her younger brother unchanged. Quietly approaching him, she begins massaging his feet, gently stroking the soles.

She then picks up a piece of chocolate that has fallen to the floor, making him eat it from her hand. Beneath the ordinary sibling bond lies a secret, intimate connection known to no one. Forbidden training unfolds between them, transforming their relationship into something entirely new.
