Season 1

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.

Ma Ri and Nak Gu head face to face in their legal dispute. They use every evidence they have to get the upper hand. Meanwhile, Woo Bin stays at Jin A's place for a while until he decides what to do. One night, the two catch the Squirrel as Woo Bin clearly remembers how he looks like. Although Jin A has one less thing to worry about, she doesn't see the trouble Woo Bin will bring.

Ma Ri decides to show no mercy and barges into the wedding hall with Jin A and Hee Soo by her side. Everyone tries to stop Ma Ri, but Ma Ri, in her angry state, cannot be stopped. In the end, Nak Gu makes changes in his plan and takes the bull by the horn as he moves in with Ma Ri. The two being back in the house together only makes the situation worse, and Nak Gu even brings an unwelcome guest into the house.

The whole family is gathered as Ma Ri and Nak Gu continue to argue over matters regarding their divorce. To make things worse, Ma Ri and Nak Gu’s mothers meddle in and make the already impossible situation even worse. Meanwhile, Hee Soo and Jin A are also going through life-changing moments of their own, which also don’t seem so rosy.

Nak Gu lies unconsciously on the floor, and Ma Ri has already left the house. Meanwhile, Ma Ri, Jin A, and Hee Soo are on their way to a place with a blood-soaked body in the trunk. Nak Gu eventually wakes up from unconsciousness and starts looking for Go Eun. However, Go Eun is nowhere to be found.

Girls and boys end up spending the night in the same villa. Unfortunately, none of the couples have their issues aligned. One thinks that both would be better off without the other, but the other is willing to risk life to stay together. In the midst of it, some things that are meant to be kept as secrets get revealed, forcing them to rely on the last resort.

Ma Ri’s plan was to lure Nak Gu to the Chulreong Bridge and see how things pan out. However, Nak Gu actually fell for her trap and ended up falling off. The police investigation begins and Ma Ri becomes the main suspect. However, without Nak Gu’s body, the investigation hits a dead end. Meanwhile, the other two girls are also going through their own once-in-a-lifetime moments.

The relief that Ma Ri expected from cutting ties with Nak Gu turns out to be something less fancy, and some sort of sadness takes her over. However, in no time, the situation takes a turn when someone least expected at Nak Gu’s funeral shows up. Meanwhile, Jin A and Hee Soo prepare themselves for the new chapter of their lives.
