[Spoiler] "The Crowned Clown" Yeo Jin-goo Goes Crazy After Death Threat

Lee Hyeon (Yeo Jin-goo) couldn't find peace at night because he was worried about assassination.

After being saved from a recent attempt on his life, he returned home and yelled, "Those imbeciles who won't accept me as their king, those who are going to suck the life out of me and those who are going to drive me mad!" Lee Gyoo (Kim Sang-kyung) followed in and asked him to put down his sword. Lee Hyeon put the sword to Lee Gyoo's neck and said, "Promise me you will kill them all even if you don't mean it".

Lee Gyoo said, "You know I will protect you with all my might". Lee Hyeon felt relieved and said, "Find a way to protect me. Hurry because I am going crazy".
