The secret he hides in the room is me.

Li Qizhou and I were brothers for six years, tighter than tight. Until that day at his place, I casually said I wanted to check out his room, and he jumped like a cat whose tail got stepped on. He'd always been so level-headed, never that flustered before. His strange reaction piqued my suspicion, and I was determined to push that door open. What he didn’t know was that I wasn’t just opening a door—I was tearing down a wall he’d spent six years building. And behind that wall, a version of Li Qizhou I’d never met was waiting for me.
