Lan Zhan thought Wei Ying had truly closed his eyes and that he is counting. He waited for a few moments.

While he was counting, he leaned forward to whisper a secret, a hint closing into the shell of his ear, warmth breath tickles him. "Wei Ying, I like books."

Now since that's a hint, it can't be considered cheating. When Wei Ying counted to ten, Lan Zhan got up and sprinted out of the lobby, through the hallway, and heads toward to the library where he's going to hide.
