Usually.
Hikaru was just, curious.
The last thing he remembered was being on the beach and seeing that girl. Ten minutes later, here he was, lost in the city with Karou nowhere to be found. She had left his sight again. There was no point in following someone who keeps disappearing. But Hikaru couldn't turn back now, he had to find the girl. Yet, in his mind, he knew he should to his brother and the rest of the club.
Hikaru was about to turn back when the girl ran right up to him. She brought her face close to his and giggled.
"You know, you're kinda cute."
With that, she ran off again, occasionally looking over her shoulder at him. Hikaru blinked and registered what just happened. He knew he couldn't be with his brother forever, but never imagined it to be this soon. However, there are somethings that happen for a reason.
