The plot is an adaptation of the web novel of the same name. It follows the life of Kang Ji-won, a middle class working woman who is diagnosed with late stage stomach cancer.

She is portrayed as an ordinary woman – timid, hardworking and in simple terms the “not so popular”. She is married to Park Min-hwan, who was initially shown as a caring partner but changes since their marriage. Post the marriage he chose to quit his job and ended up being a burden to Ji-won. Things were just made worse by his mother who thought that her son could do nothing wrong and in turn pressurized Ji-won to work harder.

The stress takes it’s toll and she ends up falling sick. In those times her closest friend Jung Soo-min was her only companion when she battling with cancer. Her friend regularly visited her during treatments and encouraged her to fight.

Little did she know that her life was about to be turned upside down when she was sent back home from the hospital due to non payment of the hospital bills. When she arrived at home the scene in front was that of her husband cheating on her with her closest friend. They all the while were plotting a way to get rid of her to cash on the life insurance.

She threw a fit of rage on discovering the truth but neither of them regretted on what they did to her. They said “The living needs to keep on living” and in the scuffle pushed her sending her crashing to the floor. She saw her life drain out of her.

When she wakes up again she is back to the year 2013. To a time before she made all the wrong decisions in her life. Given the opportunity to change her fate, she now has to make the right choices to ensure a better future than the one she lived.

The series follows the changes she makes to enact her revenge on the ones that had killed her and all the while claiming her right to to a “Fairytale Happy Ever After”. With the help of her romantic interest Yoo Ji-hyuk who seems to be in a time loop of his own they sought to alter the present to make their future one in which they finally win.

In my opinion, it is a light-hearted revenge tale which is a nice break from reality giving the viewers the motivation that it is never to late to change their destiny.
