On the episode of “Big” that was aired on the 19th of June featured Gil Da Ran (Lee Min Jung) going to the house that Kang Kyung Joon bought one year ago without her permission with Seo Yoon Jae's (Gong Yoo) money. Gil Da Ran had forgiven him and decided that it'll be Gil Da Ran and Seo Yoon Jae's newly-wed-house and even began to decorate.

Gil Da Ran goes to the house only to pack her things out of the house when she runs into Lee Se Young (Jang Hee Jin). When Lee Se Young sees Gil Da Ran, she asks, completely shocked, “Miss Da Ran, why are you here?” And Gil Da Ran responds, “I'm here because of my stuff.”

Lee Se Young then asks nosily, “Are you seeing Yoon Jae again?” To her questions, Gil Da Ran responds, “From seeing you here, I guess what I heard about you is right. Do you really want to go far as marriage?”

Gil Da Ran continued, “I would like to stop you if you were thinking of marriage. What comes to your mind when you see a 19 year old high school student? Could you be attracted to him?”

Se Young tells Gil Da Ran, “Do you think I'm crazy?”

Gil Da Ran tells Se Young, “Right now, there's an immature little child inside of Yoon Jae” and tries to warn Lee Se Young. However, Lee Se Young does not listen and says, “I obviously know that he has changed a lot since the accident. I still like him, even if he changed. I'm not going to give up like you,” and challenges Lee Min Jung.
