she liked that sound he made, that almost-laugh. it made her very happy. 

she saw him come closer as she panicked. then he said he was fine. she didn't quite believe him, but didn't quite understand why he would lie. then he told her to get away from the edge. she looked down and only at that point realized just how close she gotten and took several steps back, the height of the desk (to her) was dizzying. "what's a doctor?" she asked "do they fix things?" the last statement sounded important, the thing about his mother, but she didn't quite understand what it meant. 

she sat down and watched Yato as he crossed to the dresser and started pulling out clothes. she watched quietly as he changed, her mind not comprehending that this should be a private moment, to her it made no difference. so she simply watched and waited, until her stomach made a noise at her. she blinked, very confused, she didn't understand the feeling. her stomach didn't quite hurt but it was uncomfortable. "Yato?" she said "i'm... not feeling right..." she wasn't sure how to phrase it because she simply didn't know the words to express the sensation.
