Through The Window
The boy was startled out of his sleep by the sound of his window opening. His hand darted to the kunai that he kept under his pillow, body tensed to pounce as someone scrambled in noisily, not hiding their presence. What kind of idiot would be so loud?
"Chouko?" the person, a girl by the sounds of it, called. "Are you awake?"
The boy, Minato, turned on the light beside his bed, now realising what was going on. The girl before him blinked wide, green eyes at him, having let out a startled and nervous squeak at the sight of him. Sakura, her name was, or so Chouko had told them about her late night best friend.
"Chouko was adopted today," Minato told the girl. "They gave me her room, since I'm in the Academy now."
Sakura looked incredibly disappointed. Indeed, it seemed she might cry, but then she forced herself to stop, taking deep breaths and closing her eyes, likely counting to ten. After awhile, she looked over to him, frowned, and asked, "You look familiar. Who are you?"
"My name's Minato," he told her, noting her eyes go wide at this knowledge.
She stared at him a moment with those wide, green eyes, before she grinned and said, "My name's Haruno Sakura, and I'm from the future!"
