On the 5th episode of ‘Big’ that was aired on the 18th of June featured Jang Mari (miss A’s Suzy) trying to find Kang Kyung Joon’s (Shin Won Ho) body. Jang Ma Ri shows up to Seo Yoon Jae’s (Gong Yoo) house and invites herself in.
Kang Kyung Joon in Seo Yoon Jae’s body refuses to give the wallet to Jang Mari and begins to tease her. Jang Mari begins to search the house for the wallet but fails in locating it.
In a plot to kick Jang Mari out of Seo Yoon Jae’s house, Kang Kyung Joon in Seo Yoon Jae’s body begins to bring up his story about his first kiss. Jang Mari angrily asks, ‘Is Amy really Kang Kyung Joon’s first kiss?’ and expressed her fury. Even after hearing about Kang Kyung Joon’s first kiss, Jang Mari sits on the couch and refuses to leave.
Jang Mari then says to Kang Kyung Joon in Seo Yoon Jae’s body, ‘There’s a secret in this world that Kang Kyung Joon doesn’t know.’ and begins to smile. Jang Mari suddenly kicks Kang Kyung Joon’s most vital point and takes his wallet away.
Jang Mari quickly leaves the house to get into a taxi to leave the area. Kang Kyung Joon just rolls around on the ground in pain, unable to do anything.
