Trivia for Dr. Frost.
- I Knew It!: There were some fans who suspected that Moon would become the main antagonist from his very first appearance. They were right.
- Trolling Creator: In some of the episodes that have author's notes, he very clearly enjoys teasing fans. Especially when Moon being a good guy or a bad guy was still ambiguous.JeongBeom Lee: I get a lot of questions about Seonghyun. You're probably confused as to whether he's a good or bad guy, right? Hehehehe. Which could it be?
