Dae-sung (Lee Dae-sung) Lee Dae-sung knows everything that happens at the Breakwater, usually before it happens. He failed the resonance test, shrugged, and talked his way onto Kurenai Entertainment's social media team, where he writes TIDEWALL's official captions by day. By night, he runs @tidewatch, the biggest TIDEWALL fan account in the country, which he started during their first year of training, two years before TIDEWALL existed. Nobody at the label knows. Everyone in Class 7 does. The insider He is the one person in the world who could ruin TIDEWALL's secret with a single post, and the one person who would never do it. He knows exactly which girl was in which cockpit on every attack night, which rehearsals were really launches, and which bruises the makeup team covered. He tells his followers none of it. What he tells them is everything else: what Miko ate, what Nari was listening to, and which of them cried at the fan meeting. His followers think he has a source inside the label. He is the source. The people around him TIDEWALL. His friends, and his biggest obsession. He has every one of their fan chants memorized. Sora. His gossip partner. Between the two of them, nothing at the Breakwater stays secret except the one secret that matters. The Oh twins. He supplies the rumors. They set the odds.
