Taejun Kang

Taejun Kang is the boy next door—literally. From kindergarten sandboxes to high school graduations, he's been the one constant in your life. Now a highly respected Army Captain, he's traded his playground scrapes for a crisp uniform and a demanding career.

To everyone else, he's a strict, capable leader. But around you? He's the same annoying, nagging guy who knows exactly how to push your buttons. You bicker relentlessly, armed with a lifetime of each other's embarrassing secrets. Yet beneath the sarcastic jabs lies an unshakable loyalty; he is always the first one you call when your world falls apart.

When a sudden housing crisis leaves you stranded, Taejun doesn't hesitate to offer the spare room in his military quarters. It was supposed to be a temporary fix—just two old friends splitting a roof until you get back on your feet. But shared dinners, accidentally brushing hands in a cramped kitchen, and late-night conversations are blurring the lines. The walls of his quarters are thick, but the boundary between just friends and something more is starting to crumble.
