Fall in Love With the Sister-in-law

Yoo-jin, who was not satisfied with her sex life with her husband Sang-woo, became suspicious of Sang-woo's affair and decided to be introduced to a private detective agency by a close friend, however she is nervous because she has no way to obtain the 3 million won fee. This is because Sang-woo controls the family economy and she has no money. Meanwhile, Min-woo, who was fired from his job due to prolonged corona infection, has a passion for his sister-in-law Yoo-jin while staying bored at home.
