The Empty Bottle Heart follows Lien, a fifteen-year-old skateboarder and photographer, as she learns that the heart is an empty bottle: whatever she pours into it - kindness or bitterness, courage or fear - shapes who she becomes. After a public humiliation and the loss of a family heirloom, Lien's life tilts toward isolation. Guided by an elderly neighbor, a loyal friend, and the small rituals of community, she discovers how tiny, deliberate acts - apologies, service, forgiveness, and creative courage - clear the water inside her and let light through. This is a coming-of-age tale about choosing what to keep, how to repair what's broken, and how a single drop of kindness can change everything.
