What would you do if you fall in love with the person who caused the death of the person you were in love before? Even if its accidental, even if its unintentional; but the fact remains the same - he/she was the reason that your beloved's life was cut short. Even if you could forgive him/her, but would you be able to be with him/her with a clear conscience? would you be able to forget that 'fact'? 
Suh Jin Young absorbed herself with work after her fiance was killed in road accident the day before their wedding day. Their bestfriend Hyun Chul went abroad and left her alone dealing with her own grief because he himself was in love with her. He was on the phone with his friend when his friend got hit. The last word he said to Hyun Chul was he knows about Hyun Chul feeling and he trust him...then the sound of BAM! He went back after 5 years, thinking he was cured of his feeling but just one look and all those 5-years effort was useless...
Kim Chae Jun cant get a stable work being an ex-convict, but Director Suh Jin Young give him a chance as an aviation mechanic. Then his childhood sweetheart Min Hee left him because she dont like to live in poverty. She knows that he's willing to work hard for her to get whatever it is she want. But that just it, not anybody had to work hard just to get a bigger tv. Min Hee was materialistic in a nice way, you could understand her frustration and ambition. Furthermore, it gives reason for Min Hee to let go of Chae Jun's hand first ^_^ Chae Jun was falling for the kind and baeutiful Jin Young and she was falling for the hard working, honest, charming, cheerful Chae Jun.
Then, they later found out it was Chae Jun who hit Jin Young's fiance. It didnt help their relationship either by the fact that Jin Young was living with her dead fiance's parents as if she really are their daughter-in-law. To not broken everyone hearts, she kinda broke up with Chae Jun and try to hate him and even wished that he got beaten to death. She no longer can hide from reality by using her working endlesssly. She cant forget Chae Jun. Was it worth it to make everyone happy by living in misery? Or would you be able to be happy when you know you had broken many hearts? Tough choice, but if I were her, they were not my real parents anyway...
Then there's Min Hee and Hyun Chul. Pityful Min Hee, its alright for her to see Chae Jun in pain because of her, but when it was because of another woman, she can's stand it. Pityful, Hyun Chul, happy to be married to the one he love knowing she's in love with another man.
