An accident caused Yao Yao and Meng Xiaotian to exchange souls, opening up the experience of living in another person's body.
Without Meng Xiaotian, Yao Yao's youth might have been spent doing nothing and quarreling with her family. It was she who allowed her to reconcile with her family, it was she who allowed her to experience a different life, it was she who gave her hope for the future...
But...
"Sister Yao, that one of yours is just a dream."
"There has never been anyone named Meng Xiaotian in our school."
"Whether she's real or not, I'm grateful to her for allowing us to live together as a family."
…
"Why? But I really feel her, but I can't find her..."
Intention: friendship, family affection
