RFA as teachers
- Zen: Fun and flirty but not too over the top or else he would get fired.
- Yoosung: Nervous, extremely nervous. Would make stupid mistakes like 2 + 5 = 10
- Jaehee: Strict, thorough and effective. She's a teacher everyone respects although her classes are extremely gruelling.
- Jumin: If you do one thing wrong in his class you WILL get death stared. Guilt everybody into studying but saying it's not his fault if you don't pass. 100% believes in his students even if he doesn't show it. Call him professor Han.
- 707: A class more fun than Zen's would be Mr. Choi's. Earned a doctorate in university however he doesn't tell anyone. Mostly jokes around in class only teaching 30% of the time however when students get to exams, they realise they know more than they thought.
- "Best teacher ever? Seven Zero Seven!"
- V: His art classes are peaceful and even though everyone knows he has trouble seeing, they do their best to make him feel comfortable in such a visual class. Also teaches literature and everyone loves listening to his voice.
