Secret baby and twins short dramas

Years after a single night, a small child walks up to a stranger with the same eyes. Stories here mix romance with family comedy: tiny geniuses hack their way into boardrooms, plot to reunite their parents and outsmart every grown-up. Underneath the laughs sits an old hurt between two adults who must explain why they ever parted.
