She drew him.

Catrin took the brown book in her and Ryan, who stood on the side eyed it suspiciously. 

"You can go back and do your work, Mr. Carl," she said, and nodding to her, the butler soon left. 

Once he was gone, Catrin turned to look back at Ryan. 

She didn't say anything; simply kept her gaze on him. Ryan waited for a while but when he felt his patience thinning, he asked, "What is that?" 

Catrin heard him and tilted her chin a little with a confident smile. "Didn't you ask me how I can make you believe?" She raised the brown book in her hand and tilted her chin towards it. "Here," she said, "I will do it with this diary." 

"Diary?" Ryan glanced at the brown book and then turned back to look at Catrin, who nodded to him as sure as before.
