"A Gentleman's Dignity" Jang Dong Gun and Kim Ha Neul start dating to break up.

On the 15th episode of SBS "A Gentleman's Dignity" aired on July 14th, Seo Yi Soo asks Kim Do Jin to continue dating her.

Seo Yi Soo said to Kim Do Jin, "To think about it, it's unfair. You confessed to me and broke up with me. So follow my way of breaking up. From now on, when I call you, come to me no matter what you're doing. Promise me that you won't dislike me before I do, and promise that you will like me for a month."

She continued, "Wait until I don't think about you and can break up with you." Kim Do Jin responded, "I will do whatever Seo Yi Soo wants me to do."

Then after, she started to call him at any time and any place. She said, "I'm in front of Kang Nam Intersection crosswalk, come out. We'll go to the book store. We'll watch a movie." But, when she met with him, she didn't speak to him.

When Kim Do Jin saw her cold image, he thought about how he mistreated her in and apologized to her. The coldhearted dating style being used for the break up, developed a more interesting plot.
