The 8th episode of KBS 2TV drama 'Big' that was aired on the 26th of this month, featured Gil Da Ran (Lee Min Jung) deciding to marry Kang Kyung Joon (Shin Won Ho) in Seo Yoon Jae's (Gong Yoo) body.
Gil Choong Sik (Baek Sung Hyun) had run away from home after being humiliated in front of his love Jang Mari (miss A's Suzy). Gil Da Ran and Kang Kyung Joon team up to search for Choong Sik. Jang Mari is the first to find Gil Choong Sik but gives Gil Da Ran the wrong address after getting upset when Gil Da Ran picks up Kang Kyung Joon's phone. Jang Mari then hides Gil Choong Sik at a public Sauna.
Eventually, Kang Kyung Joon in Seo Yoon Jae's body finds Gil Choong Sik in the public sauna. Kang Kyung Joon is extremely disappointed after finding out about Jang Mari's lie and refuses to even look at her.
Jang Mari is hurt by Kang Kyung Joon's attitude and Gil Da Ran tries to make her feel better. Jang Mari reveals to Gil Da Ran, 'The reason Kang Kyung Joon doesn't like me is because he knows his mother died because of me. I lied on the day my dad was going to propose to Kyung Joon's mom. That day Kyung Joon's mother died from being shot. She wouldn't have died if she went to go meet my dad. It's all my fault.'
After hearing Jang Mari's story, Gil Da Ran visits Kyung Joon. Gil Da Ran confesses about what she heard from Jang Mari and tells him 'It's not your fault' and hugs Kang Kyung Joon.
Gil Da Ran see her ring that she lost while she was playing around with Kang Kyung Joon. Kang Kyung Joon had found it earlier and was holding on to it. When Kang Kyung Joon returns it to her, Gil Da Ran says, 'I think I like you. I'm sure that my heart still longs for you.'
Kang Kyung Joon replies, 'I know that the person Gil Da Ran is looking at is not Kang Kyung Joon. I'm not going to be childish and try to stop you from loving somebody else.'
Gil Da Ran adds, 'I'll help you grow up to be a good man. Kang Kyung Joon, marry me. I'll take care of you' and officially began their newly-wed life.
While they were at the airport getting ready to leave for their honeymoon, Kang Kyung Joon realizes that he was returned back into his body for a little bit. Kang Kyung Joon says, 'Congrats. I feel like I was really back in my body.' However, Gil Da Ran was not happy about the news. It is becoming a bigger and bigger mystery as to how this love line will play out.
