Accident
"Everyone has accidents and mistakes. No one is perfect. I mean... that's why they put erasers on the end of pencils, right?"
Satoshi Hiwatari paused, letting the words that his companion had just said sink in. "... I suppose."
"So you'll be fine!" Risa Harada said, touching his arm. "Trust me. You're THE Satoshi Hiwatari. A mistake on a math test or history test isn't going to change anything."
"I didn't mess up on a test."
"Oh... wait, then what are you talking about?"
Satoshi glanced at her. "Not a grade, if that's what you had assumed."
Risa scowled. "Then what did you mess up on?" Satoshi glared at her, the woman he hadn't seen in an entire year. She honestly couldn't be that stupid. Risa blushed, feeling stupid. "Oh, you mean leaving Azumano?"
He couldn't handle this. "Partially. Not exactly."
From the corner of his eye, he could see Risa's blush deepen. "Oh... you mean the... that thing that happened?"
"When I kissed you?"
Risa hit his arm, flustered that he had brought up such a subject. "Well, Hiwatari, I still think it's not that big of a deal. I mean... I thought it was an accident too... which it obviously was." She hesitated before mumbling, "I can't believe you still remember that."
Satoshi calmly put his hands in his pockets as she looked away and avoided eye contact. "It's hard to forget."
"Oh, please," Risa said rolling her eyes. "Once again, it was an accident... Ha, the fact that you kissed me was probably the bad part. I was your worst accident. Am I right?"
He looked at her. "No. On the contrary, you'll always be my favorite one."
Sniff. Hmph. "I'm probably your only one."
A smirk. "Actually, no. The other accident I made was letting you go."
