Disappearance

Just as An Luxia left the house, she received a call from Yu Xinyi. She sighed and picked it up, "What is it now?"

There was a pause and then Yu Xinyi screamed, "An! Lu! Xia! You will never guess what just happened!"

An Luxia put the phone a distance away from her ear because of the loudness, and the next second, she heard a deep chuckle that sounded weirdly familiar. . . 

Was that her brother?!

  "Yu Xinyi, why are you with my brother?!" She immediately interrogated, stopping in her tracks and looking at the driver to signal for him to wait.

There was another pause, "How did you know?"

  "I heard him laugh," An Luxia said with a sigh. Just a moment ago, her friend was all sad about being rejected, so what had happened now?
