The Smile Has Left Your Eyes

Under pressure, disheveled, and disoriented, Jin Kang heads off to her friend’s pottery art exhibition and hopes to meet her friend’s boyfriend, Wang Woo Sang. At the art exhibition, Jin Kang and her friend, Seung Ah, both have separate encounters with Kim Moo Young who is working there serving craft beer. Meanwhile, Yoo Jin Gook, Jin Kang’s older brother, starts to investigate the murder of a 22-year-old university student and finds something strange at the crime scene.

Seung Ah introduces her boyfriend to Jin Kang, and he is none other than Moo Young, the guy who helped Jin Kang at the brewery. Moo Young insists that they’ve met before and this is their fourth acquaintance, but Jin Kang doesn’t feel comfortable with his presence. Nevertheless, Moo Young keeps provoking her. Meanwhile, Choi Sang Hoon, the prime suspect of the murder case, is caught in Canada and gets transferred to Korea for further investigation.

Jin Kang goes to the brewery and gets acquainted with the people working there. Later on, she finds herself at the place alone with Moo Young. Seung Ah calls Moo Young, but he does not answer. Meanwhile, Choi Sang Hoon, the suspect, denies the charges against him. Furthermore, the murder weapon is found in an unexpected place.

Jin Gook strongly believes that Moo Young is related to the murder of Jeong Mi Yeon and warns Moo Young that he will catch the killer no matter what. Moo Young wishes him good luck but insists that Jin Gook gets it all wrong and he isn’t the killer. Never-theless, Jin Gook visits Lim Yu Ri, the witness, and asks her how the two were related. Meanwhile, Seung Ah is grounded for sleeping with Moo Young, and she asks Jin Kang a favor.

Jin Gook saves Jin Kang from an accident just in time. He goes to the driver’s seat to check who the driver is and finds Lim Yu Ri, lying unconscious. They take her to the hospital, and the doctor tells them that she is just a little malnourished and has taken several sleeping pills. Jin Gook calls Moo Young over and asks him whether he told Yu Ri to intentionally hurt Jin Kang.

Jin Gook desperately tries to save Yu Ri after she tries to throw herself off the building. The burn scar that Jin Gook finds on Moo Young throws him in a state of confusion. Meanwhile, Jin Kang approaches Moo Young and demands him to clear up the misunderstanding he’s caused Seung Ah, but Moo Young hints otherwise.

Jin Kang visits Moo Young’s place only to witness him getting beaten up by a bunch of thugs. Alarmed and shocked, she calls the police before running to his rescue. Moo Young is taken to the hospital but ignores the doctor’s advice and goes home. Jin Kang begs him to file a suit, but he tells her that the men were only paid to get the job done and that they are not at fault.

News of Seung Ah and Woo Sang’s car accident are all over the place. But no record of Moo Young being admitted to the same hospital or any mention of him can be found on the news. His disappearance leaves Jin Gook and Jin Kang perplexed. Meanwhile, more evidence that point to Moo Young being the likely culprit surfaces, and Cho Rong discovers that Jin Gook had been staying silent despite knowing everything.

Evidence on Jeong Mi Yeon’s murder gets found from Moo Young’s house. The secret behind the incident gets revealed. After knowing what happened, Jin Gook tells Jin Kang that Moo Young is nothing more or less than an evil mastermind. However, Jin Kang finds herself still being attracted to Moo Young.

Moo Young and Jin Kang go on their first date, hand clasped and their faces beaming with smiles. But Jin Kang keeps her relationship a secret from Jin Gook. Moo Young decides to be the good guy Jin Kang wants him to be. Meanwhile, Jin Gook opens up about something from his past to So Jung, which leaves her in shock.
