Recent episode of KBS drama 'Big' that aired on June 11th featured Kang Kyung Joon (Shin Won Ho) in Seo Yoon Jae's (Gong Yoo) body begins to develop feelings for Gil Da Ran (Lee Min Jung), his school teacher.
Kang Kyung Joon and Gil Da Ran really acted as though Kang Kyung Joon was Seo Yoon Jae. The two of them went to the hospital to fill out a leave of absence for Seo Yoon Jae. When they're about to leave, they run into Seo Yoon Jae's doctor friends and decide to go out for drinks together. Lee Se Young (Jang Hee Jin) was also present at the meeting.
Seo Yoon Jae's friend tells Gil Da Ran that Seo Yoon Jae fell in love at first sight with her. She also finds out that after seeing her, Seo Yoon Jae specifically pointed her out and asked his friend for an introduction. Gil Da Ran, drunk, asks 'Am I that pretty?' and begins to sing 'I am beautiful girl, my beauty is my weapon' and begins to dance as well.
Kang Kyung Joon then says, 'This is embarrassing. Should you really be drunk and acting this way in front of your student?' and began to tease Gil Da Ran. Gil Da Ran however, wasn't listening to anything he was saying. Instead, she tells him, 'Don't say anything for just one moment.'
Gil Da Ran's eyes were filled with love and affection. She held on to Kang Kyung Joon's hands and said 'I will be so good to Yoon Jae when he comes back. Was I that pretty? You should have told me. We would have been so lovey dovey.'
Kang Kyung Joon then decides to test Gil Da Ran. Kyung Joon wanted to test how far Gil Da Ran had gone with Seo Yoon Jae. He tells Gil Da Ran, 'A man's love grows with touch and affection' and held her hand and put one arm around her shoulder.
Gil Da Ran accepted his touch without any hesitation or awkwardness. However, when Kang Kyung Joon began to get near her face to kiss her, Gil Da Ran began hesitating and seemed nervous. Kang Kyung Joon then says, 'Up to here? This is like my level and I'm only in high school.' and teased her one more time.
