In You Who Came From the Stars, episode 5, Yoo Se Mi(played by Yoo In Na) seemed to betray Cheon Song Yi(played by Jun Ji Hyun) for her own good. As Song Yi got fired from her commercials and dramas, Se Mi called her out to comfort her. They had chicken and beer together while having a talk. Se Mi said, “They are so harsh on you. How could they just kick you out of the cast?” Just then, Se Mi received a text message asking her to star in a drama that Song Yi got fired from. Se Mi told Song Yi that her mother was sick and quickly left.
