What is a family?
What is love?
What is the self?
Lan Xuanying is trapped in a cage of her own thoughts.
Domestic violence strikes without warning, and tempers flare at any moment. The cheerful father she remembers has become a monster who abuses her mother.
Before leaving the place where she grew up, which feels like half her hometown, she inexplicably agrees to her childhood friend's request and crosses the line into young love.
She doesn't want to grow up. Growing up is too painful.
She wants to grow up quickly, so she can leave this suffocating home.
One blow after another shatters her carefree smile.
She becomes quiet and irritable, and frightening thoughts keep surfacing in her mind. Before she turns eighteen, she could act on one of them, and then Mom would finally be free.
Where will she be on her eighteenth birthday?
Will her family, on the verge of falling apart, be rebuilt or shattered completely?
Does she know who she is?
Where will she go then?
