The three friends each have their own story. Since their youth, they were wishing for a life that they thought was perfect for themselves. However, it just turns out that they live exactly the opposite lives they wished for. One who has a perverted husband, one who recently lost her husband, and one who cannot see her husband often. The three women fight alongside each other to overcome their difficulties.

Ma Ri starts to find evidence that Nak Gu is having an affair. She goes to a lawyer to plan the divorce. Meanwhile, Hee Soo also goes through a problem of her own with her husband. Her long and old dream of having a child becomes nothing because of what her husband has done. Jin A, on the other hand, has no husband issues but is still tormented by the thought of the Ogwang-dong Squirrel.

Ma Ri will not give Nak Gu what he wants. She makes it official that she will never divorce Nak Gu. Hence, Nak Gu has to keep living with Ma Ri while worrying about how she might kill him every day. Meanwhile, Jin A catches a criminal who is suspected to be the Squirrel. As the criminal gets unmasked, Jin A is shocked to see that he is someone she knows.

Ma Ri is in search of evidence that Nak Gu was having an affair on the night of a day in April 2021. She digs into a speeding ticket of that day in hopes of finding a photo of both Nak Gu and Go Eun. Nak Gu, on the other hand, goes to a divorce specialist lawyer to win against Ma Ri. He finds and makes as much evidence as possible to make sure the divorce comes through.

Ma Ri finds Nak Gu and Go Eun when the two are on their way to getting married. The aggressive car chase ends up sending Ma Ri and Nak Gu to a hospital. Meanwhile, Woo Bin suddenly appears in front of Jin A. Looking at her dead husband standing right in front of her, Jin A impulsively takes him home and locks him up in a room until she decides what to do with him.
