In You Who Came From the Stars, episode 11, Cheon Song Yi(played by Jun Ji Hyun) acted weird in front of Do Min Joon(played by Kim Soo Hyun) after getting drunk. Previously, Song Yi got rejected by Min Joon and met Lee Hwi Kyung(played by Park Hae Jin) on the way home. When she woke up the next morning, Hwi Kyung left with an uncomfortable face. Not long after, Song Yi remembered what happened last night. Last night, Song Yi sang a song crying with her eyeliner all smudged on her face. She also knocked on Min Joon’s door in the middle of the night and cried. In addition, she called Min Joon hundreds of times so he could not answer his phone.
