In You Who Came From the Stars, episode 2, Do Min Joon(played by Kim Soo Hyun) gave an ‘F’ on Cheon Song Yi(played by Jun Ji Hyun)’s assignment. Song Yi was shooting a special documentary of her daily life. At school, she submitted her assignment to Min Joon in front of the class. He took a look at her paper and called out her name. He said, “I bet you didn’t know the rules in my class since you’ve been absent for a long time. My class assignment do not allow copying others or any sources on the internet.” Then he announced out loud, “Your assignment is an ‘F’. Any complaints?” Song Yi’s story in class spread through the internet, and people started to curse on her.
