Yoseob, a street thug who smoked, slept with club chicks and was once a good boy. He was much better of a perfect boy in high school. But everything started to change when his parents died in a hit-and-run accident. He was just depressed at first, started to hurt himself with blades, drinking alcohol and things were getting worse as time passed. Most of his friends tried to convince him to stop doing those things, but do you think he cared? No. He didn't. For him, life and it's just useless to do good things when in the end, you just die.

Jieun, was a cute yet pretty little girl who hated cigarettes, smoke, clubs and dirts. She was a good girl who worked at Caffeine Cube Café. She was also familiar to everyone. She was kind, warm-hearted, a good listener and funny. She had no parents, just like Yoseob. But she would never let her feelings took place of her soul. She was strong enough as a girl. Not like Yoseob who would just give up. For her, life is precious, needs to be cared all your hearts because it's a worth one-time gift. She wanted to enjoy her life so that, her parents would be happy up there.

`i want to enjoy my life, so that my parents won't be sad and can be proud of their daughter up there.`

`what's the benefit of doing good things? you will just die when the world ends.`
