In the purgatory of Qinghe Middle School, there are two scarred islands.
Yan Yan, with the scars of domestic violence carved on his eyebrows and armor made of violence, struggles to survive under the threat of an alcoholic father and debt collectors. He is a "problem student" that everyone avoids. Li An, with old scars hidden on her wrists and a perfect report card as a mask, is walking on thin ice under the shadow of her deceased sister and the suffocating expectations of her parents. She is recognized as "the proud daughter of heaven".
A collision in the library stirred up the dust of misunderstanding; a bundle at a science and technology festival tied the knot of fate. When Yan Yan saw the teeth marks of Li An's silent collapse on the rooftop, and when Li An witnessed Yan Yan's clumsy tenderness in front of the stray cat, the cold label began to peel off. He blocked the sharp blade of rumors for her and carried the collapsed trophy on the podium; she ignited the spark of mechanical talent for him and pawned the treasured violin against the bloody paint of loan sharks.
The abyss of the original family is swallowing up, and the ghost of psychological trauma bites back. In the court, he cut off the chain of blood; in the rainstorm, she kissed his ferocious scar: "We are symbionts." From the violence of the iron chair to the collapse of the podium, from the silence of the band-aid to the brightness of the welding sparks, two broken souls groped in the embers, and finally used the scars as a basis to glimpse the glimmer of redemption in each other's cracks - it turns out that imperfection can also be deeply loved.
