that is unless it gets far darker. then well... yeah.
This kid reminds me of myself. So utterly desperate for a friend. Nobody talks to him. And Haru talks to him so of course he becomes attached to her, shes one of the few people that treats him decently.
This guy is fast! One moment he drops bicycle down the slope, next - he's behind the girl right at the short moment everyone is distracted, and none's the wiser.
