Geu Rim is a sub-writer for a radio show hosted by a party animal DJ who rarely shows up on time. One day, while taking care of the troublemaker DJ, she runs into Soo Ho, the nation's most beloved actor. Meanwhile, a legendary producer, back from his vacation in India, starts to gather people for his new radio show.

Soo Ho firmly refuses to be part of a radio show. Determined to show the arrogant actor how great radio shows are, Geu Rim comes up with a plan to persuade him.

For some reason, Soo Ho decides to be on Geu Rim's radio show. However, it's too soon for Geu Rim to celebrate as Soo Ho lays down a number of conditions. When the contract gets signed, Gang finally gets to work.

With the first recording of Soo Ho's radio show coming up, the team goes on an overnight trip to brainstorm ideas and build teamwork. However, Geu Rim finds out that she lost her laptop with the script she was working on. To her surprise, Soo Ho tags along when she goes back to look for it.

After the first recording, Gang and Soo Ho get into an argument. The two end up having drinks all night at Soo Ho's place. The next day, Ji Soo Ho's Radio Romance gets aired for the first time. Soo Ho goes into the radio booth thinking he's recording another episode. However, an unexpected situation breaks out and causes a big mess.

Gang takes Geu Rim and Soo Ho with him to see Sung Woo. He wants to use Sung Woo's booth for Radio Romance, and Sung Woo will only lend it to them under one condition. Geu Rim goes to Dongil Elementary to cover a story. However, on her way back to Seoul, she gets stuck in traffic.

The show was a success thanks to the kids at the school and Geu Rim's script. However, the kiss that night definitely made things awkward between the two. Soo Ho can't muster up the courage to tell Geu Rim about what he remembers, and Geu Rim just wants things to be professional between them. Soo Ho decides to open up more and even gets himself a cell phone.

Tae Ri waits for Soo Ho to show up to the party, but instead, she finds him with Geu Rim. When Geu Rim comes home, she finds her mother lying unconscious. Without anyone else to ask for help, she calls Soo Ho.

After Soo Ho confronts Gang, he learns about Gang's feelings toward Geu Rim. Soo Ho finds out that he's got competition. At the hospital, the girl who promised to DJ for Radio Romance says she wants out. Soo Ho is the only one who can persuade her. The more Geu Rim learns about Soo Ho, she comes to think that he's not as bad as he originally seemed to be.

Geu Rim understands Soo Ho in a way no other person ever did before. Now, winning over Geu Rim is the only thing on Soo Ho's mind. He asks for help from others so that he can become a better DJ, and at the same time, he is bothered by how close Gang and Geu Rim are.

Soo Ho reassures Geu Rim by telling her how serious he is about the radio show. He does everything in his power to do both the drama and the radio show. The team is about to disband because of the pressure on the broadcasting station from JH Entertainment. Meanwhile, Soo Ho boils over with jealousy when Geu Rim and Gang go on a date together.

As a means of retaliation, Gang does what he can to get back at JH Entertainment. While trying to find a solution, Soo Ho finds out the real reason why his show was canceled. Meanwhile, the team gets busy preparing for a new show.

Gang confesses his feelings for Geu Rim and tells her that he had held back because he didn’t want to put pressure on her. Rumors about Geu Rim entering a hotel with Soo Ho start to spread, and articles about them dating each other are published. Meanwhile, Joo Ha offers Geu Rim to be signed as a writer for her company, but Geu Rim refuses the offer.

During the radio show, Soo Ho receives a call from the president of his fan club and openly admits that he is dating Geu Rim. Soo Ho realizes that Jason was sending those unpleasant postcards. Geu Rim ends up seeing one of those postcards and tries to ask Jason about what that meant, but he tells her to ask Soo Ho instead.

Soo Ho tells Geu Rim about his relationship with Woo Ji Woo in the past. Geu Rim understands him. Da Seul tells the press that she and Yoon Seok were having an affair and claims that Soo Ho’s family is a fake. Meanwhile, Soo Ho calls a press conference and admits that his family is indeed a fake.

Soo Ho has a hard time after revealing that his family is a fake. Jason tells Soo Ho that his intentions of helping him had only made things worse, and Joo Ha only wanted to know more about him because she cares about him. Meanwhile, Gang is summoned by Korea Communications Commission for the troubles caused by the radio program.
