When she was sixteen years old, Xu Anmeng found this sentence in her sister Xu Linge's diary: "I hate the same blood in our bodies, but I am secretly happy about it. It is a shackle that can lock you to me forever."
Four years later, the sister who had "abandoned" her for many years blocked her in front of the sink. The cold scent of perfume penetrated her eardrums with her hot breath: "It's been four years, haven't you had enough trouble?"
Everyone said that the eldest daughter of the Xu family was an iceberg who couldn't hold herself warm, but only she knew how paranoid and hot her sister was under her cold appearance.
When she once again fell into the abyss that melted only for her, she discovered that the chain had never been loosened.
