In You Who Came From the Stars, episode 6, Do Min Joon(played by Kim Soo Hyun) and Lee Hwi Kyung(played by Park Hae Jin) argued over Cheon Song Yi(played by Jun Ji Hyun). Previously, Lee Jae Kyung(played by Shin Sung Rok) found out that Song Yi had the evidence of him killing Han Yoo Ra(played by Yoo In Young), and went to Song Yi’s house to get rid of her. Min Joon noticed this and went over to her house, when he saw Hwi Kyung there. After Jae Kyung left, Min Joon and Hwi Kyung started to have nerve war. Hwi Kyung said, “You have such a bad impression.” Min Joon replied, “You’re the first one to say that.” Song Yi, who was watching them, told them both to leave her house.
