What exactly?
"You heard?" Lin Yan, who had drunk a fair share of mixed drinks, fell asleep. Su Wan stayed by his side until his breath evened out, and only then did she walk away from him. However, as soon as she walked out of the room, she decided to address the person standing all along by Lin Yan's room.
Lin Yu limped out of his hiding place, his expression carefully blank as if he was trying to hide whatever thoughts were going on his head. Su Wan wasn't surprised. She had felt his presence when she came out of the room to make Lin Yan a drink. She just chose to ignore him as she had nothing to hide.
Su Wan looked at him and waited for him to say something or call her out for being a liar or a fraud. Still, even after waiting for a good ten minutes, Lin Yu didn't seem willing to say anything about it.
