I Gyeong is a nameless singer-songwriter who has a miserable past. She goes to Ha Rip after finding out he released the song she wrote, and Ha Rip realizes that all his music are stolen and inspirations from others. Out of guilt, Ha Rip wants to terminate the contract. However, there is a price to pay for.

I Gyeong decides to quit music and to find a new dream. Meanwhile, Ha Rip tries to find his replacement to carry through on his promise with Tae Kang. He manages to find someone who is desperate to be a musician and introduce the person to Tae Kang. However, Tae Kang says that he can’t accept the person as Ha Rip’s replacement.

I Gyeong decides to quit music and starts working at Ha Rip’s house as a housekeeper with Kang Ha’s help. However, Ha Rip is being harsh on her and asks her to stay out of his sight. Meanwhile, Ha Rip is still struggling to find a first-grade soul, and Tae Kang suggests him looking close to home. All of a sudden, Ha Rip has a feeling that I Gyeong might be the one.

I Gyeong’s first performance goes viral online, but she doesn’t want to keep doing music. Tae Kang tries to prove that I Gyeong does not have the first-grade soul by testing her. Meanwhile, I Gyeong and Lucca run into each other in front of Seo Dong Cheon’s old house. They share their stories of how they got to know about Seo Dong Cheon.

Despite the controversy about I Gyeong’s past, Ha Rip decides to sign her as Soul Entertainment’s artist. I Gyeong is happy because she can finally fulfill her dream as a singer, but she doesn’t know the real plan Ha Rip has on his mind. Meanwhile, Ha Rip, I Gyeong and Lucca are preparing for I Gyeong’s first busking.

Ha Rip finds out that I Gyeong is the girl who he met 10 years ago when he was Dong Cheon. She was a girl who lived in his neighborhood, and her life changed dramatically by his small advice. Ha Rip goes to see Tae Kang, but he doesn’t give the answer he wants. Meanwhile, I Gyeong holds a press conference to talk about her past.

I Gyeong stands in front of the press and shares her past. As the reporters start crashing on her, Ha Rip comes up and clears the misled assumptions of the relationship between him and her. They start recording more music with I Gyeong and Ha Rip discovers that I Gyeong was the girl who was falsely accused of theft on a wedding day years ago. He was the main culprit of the event, and he didn’t know it would have such an impact on her life.

Seo Young decides to let I Gyeong cover Dong Cheon’s old song. I Gyeong’s version of the song becomes a hit and the public starts to pay attention to the singer Seo Dong Cheon. Meanwhile, Lucca faints, and Rip takes him to the hospital. The doctor says Lucca’s condition is only getting worse, but Lucca insists on performing on stage.

Chung Ryul and Seo Young would like to make money out of Seo Dong Cheon by saying Ha Rip is Dong Cheon’s son, but Ha Rip insists that Dong Cheon will never reappear. Meanwhile, Lucca gets surgery but he is dying. Ha Rip begs Tae Kang to save Lucca, and Tae Kang won’t do so unless Ha Rip brings I Gyeong’s soul to him.

Lucca almost dies while he is having surgery, but a miracle happens. He wakes up with his disease all cured. Meanwhile, I Gyeong’s brother tells Rip the truth about the day his father collapsed. After hearing that, Rip thinks that he should make things right and decides to let the people know about the truth.

Tae Kang turns Ha Rip into the old Dong Cheon with his trick, but the conscience and consideration still remain. In order to have I Gyeong’s soul, Tae Kang gets rid of the inconvenience that makes Ha Rip hesitate and ponder so that Ha Rip would do everything he can to bring him what he wants.

On the road where Lucca died, I Gyeong cries out. As Rip says, I Gyeong sells her soul to Ryu in order to save Lucca. After signing the deal with the devil, people around her don’t suffer their miserable lives anymore. However, the way I Gyeong behaves completely changes. She becomes more ambitious than ever.

Seo Young willingly steps back from Soul Entertainment. Lucca asks Ryu to put everything back to normal for both Kelly and his dad. Kyung Soo gets mad at Taek Sang for assaulting Sun Sim. Ha Rip receives a bill from the deity saying that his 10-year contract will be expired in 10 days.

I Gyeong cannot make songs anymore. Rip desperately wants to help her and get back her soul, but there’s not much time left for him before his soul is collected. Meanwhile, Lucca decides to go back to Montenegro and says goodbye to Rip at the airport. Then, Lucca’s mother asks Rip to relay a message to Dong Cheon.

Ha Rip turns the world upside down with his confession and disappears. With only two days left remaining on his contract, he makes his way to the desert. When his time was up, Tae Kang appears in front of him to collect his soul. One year late, Seo Young discovers Ha Rip accidentally.

Ha Rip is a successful composer, and all of his songs top the charts and win many awards. One day, he is informed that his 10-year contract with the devil will soon terminate, and as per the contract, the devil will take Ha Rip’s soul. And he gets involved in strange situations. What is the true identity of Ha Rip?
