"Secret Love" Ji Sung acts like a irresponsible rich boy without any common sense.

September 25, the first episode of the KBS drama "Secret love" featured Jo Min Hyuk (Ji Sung) giving the toll gate girl Kang Yoo Jung (Hwang Jung Eum) the engagement ring he wanted to give Shin Se Yeon (Lee Da Hee) after she rejects it.

Jo Min Hyuk obeys his parents' wishes for an arranged marriage with Shin Se Yeon and goes to the airport to pick her up. He takes out the engagement ring carelessly and pushes it in her face. Shin Se Yeon tells him not to do things so forcefully just because his father ordered him to do so and ignores the ring.

However, Jo Min Hyuk tells her to just take the ring without expecting any romance since their engagement is like a business deal anyway. Shin Se Yeon tells him to throw out the ring if it's such a simple thing.

When Jo Min Hyuk drives into a toll gate, he sees Kang Yoo Jung, who was his designated driver the other night. He then hands Kang Yoo Jung the engagement ring instead since he doesn't have any money for the toll.

Both, Shin Se Yeon and Kang Yoo Jung hesitate. Even though Kang Yoo Jung refuses, Jo Min Hyuk throws the ring at her. Kang Yoo Jung comes out of the toll box and knocks on his window to return it. However, Jo Min Hyuk just tells her to hold on to the ring that that he'll come back to pick it up from her then drives off.

Even though Shin Se Yeon appeared as though she can't stand Jo Min Hyuk, she announces at the meeting of the two families that she will marry him.
