You felt like you were being watched. You were walking back home at night, and couldn't help but feel like someone was watching your every move. What you didn't know, was that it was Hua Cheng. He's been watching you and grew fond of you. More in fact, he pretty much wanted you for himself. He didn't want to scare you with his true form, so he changed into his human form and went by San Lang.

He came behind you and said, "Do you want me to walk with you ? It can be dangerous walking alone."
