Barbara, an independent, conservative, and strong-willed woman, has chosen to live alone, enjoying the peace and order of her home. However, everything is turned upside down when Harry, a carefree, eccentric, and hopelessly lazy young man, suddenly appears, claiming to be a distant relative and using their questionable family connection as an excuse to move into her home.

The two have completely opposite personalities and views on life. Their forced cohabitation leads to constant clashes, misunderstandings, and hilarious situations. While Barbara desperately tries to get rid of her unwelcome guest, their relationship develops in unexpected ways, proving that opposites attract.
