On the 'Big' episode that aired on June 26th, Kang Kyung Joon's (Gong Yoo) hurtful past was revealed. Jang Mari (Bae Suzy) lied again to get in between Kyung Joon's love for Da Ran.

Gil Choong Shik (Baek Sung Hyun) confessed to Jang Mari but his confession failed and due to the shock, he runs away from home.

Kang Kyung Joon asks Ma Ri to help find Choong Shik. With the help of Choong Shik's friends, Ma Ri finds out where Choong Shik is, but sends Da Ran to the under grounds of the subway stations.

Ma Ri and Kyung Joon head to a spa and find Choon Shik there while Da Ran, is near danger searching for her brother in the underground subway stations.

Kyung Joon gets mad at Ma Ri for lying again and does not deal with her anymore. Due to Kyung Joon's reaction, Ma Ri cries and looks back at the past and tells Da Ran, "Kyung Joon's mom died cause of me."

In the past, Jang Mari's father and Kang Kyung Joon's mother was in a very serious relationship that they were about to get married. The night where Ma Ri's father was going to propose to Kyung Joon's mother, Ma Ri persuades Kyung Joon in opposing their marriage. So, Kyung Joon holds onto his mom and doesn't let her go and at that moment, a robber carrying a gun appears and shoots Kyung Joon's mother.

Kang Kyung Joon lost his mother in front of his eyes. Gil Da Ran who now knows this fact, meets up with Kang Kyung Joon and hugs him from the back saying "It's not your fault. It's not because of you."
