Because I want to

Gan Dewei saw Ru Shi coming towards his car so he opened the door for her. Seeing that Ru Shi fastened her steps and then got into the car. She closed the door. "I thought you run away after doing that then you dropped a message which clearly depicted that you are angry when I should be the one to get angry at you," Ru Shi asserted as she closed the door. She turned her head to look at him when she paused. 

"What has happened to you? Why are you injured?" Ru Shi asked worriedly. There were bruises of Gan Dewei's face. Blood was coming out from the side of his lips. "Let's break up," said Han Dewei. 

"What?" Ru Shi exclaimed. 

"You are not the one made for me. So, let's break up," he pronounced again. Ru Shi stared into his eyes for a while and then said, "I don't want to. First let's go to the hospital." 

"No, I am going home," said Gan Dewei and averted his gaze. "I will not call you ever again. Let's stop here," Gan Dewei said.
