One appointment. That's all it took. When Hwang Ara walked into the hospital for a routine shoulder treatment, she expected to be back at practice before sunset. Instead, she woke to a world consumed by silence. Cities burned. The people she loved were gone. And the only thing left alive... wasn't human. Armed with secrets she'd spent years hiding-even from BTS themselves-Ara begins a desperate journey across a fallen South Korea in search of her family, her brother, and the only place rumored to survive the end of the world. But somewhere beyond the ruins... Seven members of BTS are searching for her. Eight members of Stray Kids believe she's already dead. In a world where one bite can end everything, hope may be the most dangerous thing left to hold on to. No cure. No escape. No second chances

Some connections are never really explained... only felt. In a world full of lights, schedules, and carefully built smiles, something unspoken keeps pulling two people closer-quietly, dangerously, without permission. Nothing about it makes sense. Not the timing. Not the circumstances. Not the way their thoughts keep drifting back to each other when they shouldn't. And yet... it lingers. Between silence and chaos, between distance and closeness, something begins to change. But the question is not what it is. It's how long it can stay hidden.
