Class 7 Regulars (Overview) Every class has the people who aren't the main story but make it feel real. They're in the cafeteria, the hallway, the back row of combat review and the gallery of every sim match. These are Class 7's regulars, plus one junior who never leaves Aya alone. Each has a page of their own. Lee Dae-sung, 23. The label's social media team by day, secret admin of the biggest TIDEWALL fan account in the country by night. Oh Ha-eun and Oh Ha-jun, 22. The twins who run the sim bay rigs and the unofficial betting book on everything. Choi Mirae, 20. A junior from Class 9 who has followed Aya since her first day. Park Gun-woo, 24. Tae's roommate, and certain that this is his year. Nam Sora, 23. The stylist who covers the cockpit bruises before every show.
