"Even if the world deceives you, don't feel sorrow or be indignant. Nevertheless, Love still exists."
In 2003, a 27 years old man lives in a corner of Seoul. His job is a conman. He enjoys defrauding the rich women of their money by temptation. He didn't get married but has a 7 years old daughter. So to speak, he's an unwed father. His daughter stays two-thirds of a year in the hospital. He has to live with instant noodles after paying for her medical fee. He is an high school drop out. When he was in high school, he had to go to the prison for beating up a man. So to speak, he's an ex-convict. He lost his parents by a traffic accident and then his uncle, a conman, brought him up. At the age of 10 years old, he was adopted into a rich family after his uncle had left him. The day he was left alone, he met his destiny, Eun-Hwan, and she was his whole world.

His life had shone once. When he, in fifth-grade, was adopted as a son of a rich family, he had the life like a dream. The dream kept up for just 8 years. He was 17 years old when he was discarded by the breach of a contract. What a life!! But he has filled with hopes. he always smiles and knows about 100 jokes. If he meets acquainted people, he greets loudly and pleasantly says 'Hello! It's a lovely day, isn't it?'

He is not insane. The force preserving him is love. To elaborate, it's his destiny, 'Chea Eun-Hwan' & his daughter 'Cha Bo-Ri'. Every time he wanted to take drugs, every time he wanted to jump off the bridge, the force of love held onto his hands & legs.
This drama is a story about the love of this man.
Chea Eun-Hwan & the man have loved for 15 years. But they didn't hug or say a word about love at all. Their path always missed each other. Prejudice & Hypocrisy of the world deceive and afflict them. When other lovers communicated by touching & words of love, they wasted their time on meaningless words and actions.

They believe in love.
The sad world that trusted machines more than people, money more than love... To these vunerable people, Sang-Do says,

Love exists! Only love is the hope!
