Who killed my father?

"Where are you taking me to?" Ru Shi inquired, looking at Gan Dewei who did not respond. Ru Shi took out her phone when Gan Dewei snatched her phone away. "What do you think you are doing? Give my phone right away," muttered Ru Shi in anger. 

"I am not going to harm you. I will never. So, be quiet," stated Gan Dewei. 

"Where are you taking me to? I have works to do," asserted Ru Shi. Gan Dewei told her to be quiet and kept driving. After 30 minutes, Gan Dewei applied the brakes, in front of a grand hotel. He told Ru Shi to step down who refused to do so. Gan Dewei got out of the car and then pulled her out from the other side. He handed the keys to the chauffeur there, thus telling him to park the car and walked in with Ru Shi.
