On a hot summer day by a small lake, Mia asks Hugo - 15 years old and yet already blasé - to tell her about his love story with Chaïnes. Despite his reluctance, memories come to the surface: evenings spent at the edge of the lake trying to seduce her, the fear felt when declaring his love, the torment provoked by this exuberant but secretive girl who never shows her emotions. The moments of pleasure still hurt: afternoons spent jostling, touching, and sometimes even fighting each other. The joy of shouting, of insulting each other, of feeling alive. And all around, like a choir, Mia and her siblings, who were learning to fish that season.
