Zhou Ting was born with a special constitution: pain transfer. Whenever someone intentionally hurts her, the pain is reflected back identically onto the assailant, while she remains completely unharmed. From her infancy to primary school, this ability made everyone who wanted to bully her suffer hidden losses, and also saddled her with a reputation for being dark beyond measure. Her father, Zhou Jinbo, divorced her mother for a third party, Song Meizhi. Song Meizhi brought her 16-year-old daughter, Song Jiayue, to move into the house, and the conflicts of a reconstituted family erupted from there.
