One is a tough girl who was abandoned by her original family and takes care of her seriously ill grandmother alone; the other is a taciturn young man who is burdened with the shadow of violence but has a burning heart.
The secret ideas for solving problems on the scratch paper, the silent shelter in the alley, the life-saving money collected in front of the hospital bed, the agreement to spend the future together in the library - they pulled each other in the quagmire of poverty and pain, and used the clumsiest tenderness to piece together a complete soul for each other.
But the shadow of their original family follows them like a shadow. The threat from their father, the pressure of reality, and the fork in the college entrance examination push them to desperate situations time and time again.
