Who are you? - SEOKSOO

Jisoo's mind began to race. Maybe he had misheard; maybe Seungcheol was right and all those all-nighters had finally killed his brain cells, because there was no way Seokmin Park had said that.

-What did you say? -Jisoo asked, completely baffled.

-"S-sorry, let me help you"? -Seokmin replied with a voice full of doubt and a gesture that was a far cry from his usual expression of indifference-the one that had caused their first fight.

-... Are you sure they didn't swap your brain at the hospital, Park?.

Seokmin Park was a spoiled heir with a venomous tongue; Seokmin Lee was the literal personification of sunshine. They shared the same face, but lived worlds apart-until a nightmare about a car crash became Seokmin Lee's reality.

Waking up in a cold hospital bed, Seokmin Lee discovers he's no longer in his cozy home; he's trapped in the body of a boy hated by half the school. Meanwhile, Jisoo Hong, who spent years loathing Seokmin Park's arrogance, is left reeling. The boy who was once his greatest nightmare has returned from the accident with a smile so genuine, it's starting to look dangerously cute.

But as Lee navigates the ruins of Park's reputation, a chilling realization sets in: the bridge between worlds works both ways. Somewhere in a dimension of warmth and love, the real Seokmin Park has just woken up in Lee's bed-and he is even more confused at waking up in such a bright dimension.
