Suzy went through a mental breakdown following Gong Yoo's confession.

On the episode of KBS2's Monday-Tuesday drama 'Big' that aired on the 12th, Kyoung Joon (Yoon Jae/Gong Yoo) hatches a plan to send Ma Ri (played by Bae Suzy) back to America.

During the episode, Kyoung Joon sees Ma Ri, who has come to the hospital that his body is at to visit him, and confronts her angrily, saying, "I told you to go back quietly. Why are you here?" Ma Ri, who does not realize that the two men have switched bodies, in turn raises her voice, saying, "Why did you lie to me? You quack-fraud!"

She goes on to drop the bombshell news that she is planning to take Kyoung Joon with her to America, to which Kyoung Joon replies, "But Kyoung Joon has someone he likes right here", pointing to Da Ran (played by Lee Min Jung).

Adding fuel to Ma Ri's jealousy, Kyoung Joon also reminisces about his first encounters with Da Ran before switching bodies, saying, "Apparently he followed her off the bus that first time because he liked her... and after that they also ran into each other at the furniture store."

Ma Ri, stricken by the news, stammers, "No way. I walked around staring so hard after Kyoung Joon said he likes women with charisma like Angelina Jolie... but why?"

To cap it all off, Kyoung Joon claims that "it's because she's so pretty. I'm getting a vibe from that body, and the person he needs is Gil Da Ran, not you", sending Ma Ri into a state of shock.
