Ganghak High is loud. Violent. The kind of place where silence makes you a target, and being unnoticed can be a survival tactic. Bella figured that out on the first day. No one talked to them—not out of respect, but because they looked like they wouldn’t last long. Geum Seong-je saw them once in the hallway—headphones in, hood up, eyes unreadable. Not afraid, but… distant. Like they didn’t belong here and didn’t care to pretend otherwise. He sized them up, made a mental note: not a threat. Just quiet. But then they kept showing up. In the background of brawls, never flinching. In the courtyard, reading while some kid got the shit kicked out of him ten feet away. In class, always deadpan, eyes half-lidded, like none of this mattered. And that started to bug Seong-je more than it should have. It wasn’t until a week later that things shifted. Bella had been cornered behind the school by one of the lower-tier delinquents—some idiot trying to prove himself. He thought picking on the quiet new kid would earn him clout. Big mistake.Word got back to Seong-je before the kid could even finish throwing his first punch. Not because Seong-je cared about Bella. Not yet. But because no one started fights in his territory without his say-so. He found the punk leaning over Bella near the back wall, smirking like he was in control.Seong-je didn’t say anything at first. He just walked up behind the guy, wrapped a hand around the back of his neck, and slammed him into the brick hard enough to leave a crack. "Did I say you could touch them?" Seong-je voice was low, dangerous. The kind that didn’t need to shout to terrify. "Don’t touch what’s mine."The kid tried to stammer out a protest, but Seong-je was already dragging him away like trash, muttering under his breath. Bella just watched it happen—calm, still. Almost bored. And maybe that is what got to him most.
A seemingly friendly and harmless engineer who works as a crucial player in the unfolding mysteries and the central antagonist.

After that, things got weird.
Seong-je started watching them. Not openly, but anyone who knew him could tell his focus had shifted. He'd linger outside their classroom. Sit just close enough at lunch that people noticed. Fights got shorter when Bella was nearby, like Seong-je didn’t want to show too much in front of them.
Some people whisper that Seong Je has gotten soft.*
