You got your answer right there in your words.

Arwen's eyes turned cold the moment she saw Ryan. Her gaze flickered to his hands gripping her arms, and without hesitation, she shrugged them off, stepping away. 

The repulsion on her face was unmistakable. 

Ryan's expression darkened. His jaws tightened, but he forced himself to remain calm. Silently, he took a step forward and lifted his jacket, attempting to drape it over her shoulders. 

Here, wear this," he said. "It's cold outside, and you are shivering." 

Arwen took another step back, rejecting his gesture without a second thought. "Even if I am," she said icily, "I don't need your coat to keep myself warm. Thanks, … but no thanks." 

With that, she turned to leave. 

But before she could even take a single step, Ryan's hand shot out, gripping her arm by force.
