In You Who Came From the Stars, episode 18, Cheon Song Yi(played by Jun Ji Hyun) and Do Min Joon(played by Kim Soo Hyun) went on a trip together. Song Yi saw a bed and lied down. As she told Min Joon to lie down next to her, Min Joon hesitated at first but listened to her. Song Yi laid her head on his arm and hugged him around his waist. Min Joon was frozen and did not know what to do. The next day, Min Joon was preparing breakfast when Song Yi came and hugged him from behind. The two spent a happy time together just as any other couple.
