This story is set in an alternate era. Ye Nanyi, a modern orphan, unexpectedly obtains a space when she is 12 years old. However, since there are surveillance cameras everywhere in the future, the space does not play a significant role.

Ever since obtaining that space, Ye Nanyi has been having recurring dreams. The girl in her dreams looks remarkably like Ye Nanyi, but unlike Ye Nanyi, although she is an orphan, she has never suffered any harm.

The little girl in the dream went from heaven to hell after losing her father when she was 5 years old.

After her biological mother remarried her first love, she immediately changed her attitude, constantly abusing the little girl. Her hypocritical stepfather also constantly hurt the little girl's stepsiblings.

An accident occurs, and Ye Nanyi takes the place of the little girl. What actions will she take? As Ye Nanyi continues to gain the little girl's memories, how will she take revenge on these people?

After taking revenge, how will Ye Nanyi survive in this era?
