In You Who Came From the Stars, episode 18, Lee Hwi Kyung(played by Park Hae Jin) said to Lee Jae Kyung(played by Shin Sung Rok) that he is not his brother anymore. Hwi Kyung brought Jae Kyung’s ex-wife and a detective along with him and called Jae Kyung. Jae Kyung’s ex-wife said to him, “It’s been seven years already. Since you locked me up in a mental hospital.” Jae Kyung said, “I don’t know what you’re talking about.” Just then, Hwi Kyung appeared and said, “I wanted to give you a chance. A chance for you to acknowledge your wrongs and regret. But now I’m going to give up. And I’m going to give up on calling you my brother from now on.” He added, “You’re not my brother anymore.” Then he left.
