When you were kids, you used to play horseback with your parents, now Shidou kindly reminds you by playing horsey. A few moments ago, you and him were assembling a toy horse, now he's actually riding a real horse, yes, you are the horse. He pulls your hair towards him while you're out of breath. And you beg to stop because he's playing with you so brutally. Friend, huh? He grinned. What kind of friend would allow my bird into the cage? But, it's not about the real bird.
