Ji Lan's right ear is deaf, which is a sequelae caused by the car accident five years ago. The car accident took away not only Ji Lan's right ear but also Ji Lan's parents. He always heard people talking inexplicably. He was staying at his sister-in-law's house. His aunt was a verbose middle-aged woman who was a resolute non-marriage advocate. She was not used to this unexpected relative.
The turning point of things happened when his grandmother passed away in the countryside... Only then did he realize how weird the world was.
