Haruka got a little shock from the familiar honourific, it had been a long time since anyone had used 'chan' after her name. She was a little surprised by it and although normally it would have bothered her, she found she couldnt bring herself to care this time, smiling at Mira and Tohru both. She noted the colour of her cheeks again and the small motion of her hand, recognising the significance and feeling another jolt of self-satisfaction. She tried to suppress this though, it was no good being so pleased with yourself, instead she answered the question. 

"I tend to remember all of the first years, I wander around the campus alot so I generally meet everyone at least once." But wait, Ru-chan? That was a very familiar way of greeting each other. Were they good friends? From the way Tohru was looking at Mira she would say so. Hmm, it bothered her just a little bit, was this and Tohru's antagonism to her connected?
