the security company Jang Taesan worked for goes bankrupt, and he becomes an unemployed man wandering around Noryangjin-dong. He loses his life saving an elementary school student who was almost hit by a car. But thanks to his good deed, he goes 14 years back in time and is welcomed to a new life. However the joy of being revived is short-lived. The thought of having to take the college entrance exam again makes me dizzy… But I remember all of the CSAT problems that I encountered while studying and the stock market graph I saw while working as a stockbroker…?! The last life was ruined, but the this next life will become a success!
