At a wealthy dinner party, business upstart Yu Chen and his wife Cheng Weiyi pretend to be a loving couple in front of everyone, but in fact their relationship is cold and distant.
After returning to the mansion, the two had a heated argument because Cheng Weiyi insisted on participating in volunteer teaching activities in impoverished mountainous areas.
Yu Chen prohibited his wife from going there on the grounds of protection, while Cheng Weiyi accused her husband of being controlling and never respecting her wishes.
An accident caused the two to switch bodies in anger, and they panicked to find that they were trapped in each other's bodies.
Cheng Weiyi (played by Yu Chen) was forced to take over her husband's transnational business negotiations, while Yu Chen (played by Cheng Weiyi) experienced his wife's daily life "as he wished"
