There was a Korean couple named Ae-young and Chan-woo. Ae-young was a delightful young lady and had a beautiful feature, Chan-woo was very smart and loved Ae-young dearly. Chan-woo worked a lot and took well of his business, Ae-young also started her own company at a cafe shop not too far from Chan-woo.
Ae-young woke up and found Chan-woo not in bed. She sighed and went on with her morning routine. She looked at the time and saw that she was running late for work. She starts to hurry and run the whole way to her cafe. She sees that there were a lot of people lining up in front of the door, she was smiling as she knew that her cafe might as well be successful. She runs inside and bows down to say sorry to the customers.
It has been 6 hours and it was getting late she was thinking of what to make for dinner. She tries to call Chan-woo but he did not respond, she starts to get suspicious for why he comes home late and why he leaves home early. "Chan-woo only started his business why is he this busy?" She starts to think. Ae-young decided to visit him at work, and made a little feed for him, she closes down the store and starts to walk off.
It was loud since they lived near the city, she walks getting near to her destination as she sees the glass door reflecting on her. She sees the room crowded with people rushing with papers in their hands. She goes to the main office where Chan-woo will spend most of his time, she sees the door and opens it. Her tears start to flow as she sees Chan-woo with another girl, she was crying not even noticing that he was looking at her, she leaves the door immediately.
Chan-woo pushes the girl and runs up to Ae-young, he grabs her wrist and tries to tell her that it was a misunderstanding. Ae-young cried on and runs off. Chan-woo sees her run outside and continues chasing after her. Ae-young didn't care about the others that were staring at her she wasn't even paying attention to where she was walking, Chan-woo sees her crossing the road, and sees that a car was on full speed.
He tries to run up to her and sees that he was too late, he sees her flying up the sky as she got hit by the car. Chan-woo was heartbroken seeing her covered all in blood, he cries non stop seeing her, his regret was cheating on her and her regret was being with him.
They both regretted...
