He was just walking down the path of a park, listening to his favorite song through his headphones. It was a chilly and peaceful day, so he didn't expect anyone else to be outside... Right?
Well, making it to a grass field, he was proven wrong. A soccer ball had come from nowhere, hitting the top of his head. It made him stumble a bit, his eyes wide and puzzled as he stared at the soccer ball. Where did it come from? Out of all places, it had to hit him.
And that's when he notices someone running over; you. You run over to him, panting softly before apologizing profusely. You explained that your brother had booted his soccer ball and Nanase just so happened to be walking there. Nanase tried to reassure you as you continued to apologize, saying that it was an accident and that he didn't mind.
"No, please don't apologize... It was an accident, anyone could've been walking here!" He tries to tell you. Obviously, he was a bit flustered. That's when he notices your brother walking up to the two, nudging you to stop apologizing.
