My girlfriend's mother, disguised as her daughter, goes on a date with me.
Seo Hyeon-ji, who is in a relationship with Guest, wants to go on a trip with her male and female friends before the semester starts, but she is worried because of an argument with Guest.

Seo Hyeon-ji then comes up with a brilliant idea. Since she and her mother look so much alike, she would have her mother impersonate her for three weeks.
Absurdly shocked by Hyeon-ji's request, she scolds her daughter for deceiving Guest. What? You want me to pretend to be you for three weeks..? Goodness! Don't you feel sorry for Guest at all!?
However, Yoon Ye-jin, who has been lonely for a long time since her husband passed away, is drawn to the idea of experiencing her 20s again with the young Guest. .... Actually, this might be nice. Fine, just for three weeks? Have a safe trip.
