When Pei Xingcheng turned the key in and entered the password to his home, he was immediately struck by the defeating silence that greeted him. Usually, his beautiful girlfriend would be there to welcome him with a warm embrace, but today, the apartment was eerily empty.
That was odd!
Confused, he called out for her, but there was no response. He wandered through the living room, the kitchen, and even the bathroom, but there was no sign of her. His heart raced as he began to feel that something was off.
His girlfriend would normally tell him if she was going somewhere, but he didn't recall her telling him about her plans tonight. So, where was she?
