Risky Romance

After an unfortunate accident, Seung Joo has become a completely different person. To find out the cause, In Ah continuously suggests to Seung Joo that he should get examined, but she is rebuffed each time. She becomes suspicious when she notices Seung Joo reacts with hostility only towards her.

Seung Joo, In Ah, and Jae Hwan head to Krabi, Thailand, on a business trip. As Seung Joo's misunderstandings about In Ah grow, his words toward her become increasingly harsher and hurt her. In Ah tries her best to understand Seung Joo and his actions, but she loses her temper in the end.

Seung Joo begins to follow In Ah around to find a way to have her kicked out of the hospital. As fate would have it, In Ah unwittingly ends up in a personal relationship with a patient. Seung Joo witnesses this and reports In Ah, putting her in danger of being fired from the hospital.

Seung Joo is feeling miserable after a failed operation. To make matters worse, video surfaces online that shows him getting into a fight with a reporter. He is enraged when he falsely believes In Ah to be the one who uploaded the video. Meanwhile, after leaving the hospital, In Ah decides to open her clinic.

Seung Joo is furious when he hears news that In Ah's clinic has opened. Jae Hwan can't understand Seung Joo's increasingly excessive behavior. Meanwhile, Se Ra is afraid the truth will be revealed when she finds out Jae Hwan is trying to restore Han-sung's cell phone.

In Ah and Seung Joo run into each other by coincidence on Hwa Ahn Island. While spending time together, Seung Joo is again suspicious of In Ah and her true self.
