Ten years after her parents divorced, her strong and cool sister Su Wan took back her younger sister Su Nuonuo, whose mind was stuck at six or seven years old and was always called "idiot" by others.
Nuo Nuo is weak, timid and loves to cry, and is ignorant and clumsy in the outside world. Everyone despises her, but she is the only one who can always quietly stand in her sister's shoes, feel sorry for Su Wan, and understand Su Wan.
All the members of the Su family doted on this cute little crybaby, but Su Wan was the only one who loved him and loved him, and would still discipline him harshly when he made mistakes.
When she was punished, Nuo Nuo would be so frightened that her eyes would turn red, and she would shy away from being punished. She would turn around and throw herself into her sister's arms, crying, and let Su take medicine and hug her softly.
Su Wan always has a hard mouth but a soft heart: Others can bully me, but they are not allowed to call my sister stupid; anger is just anger, my little Nuo Nuo can only be pampered by me.
