First of all, I do not own Katekyo Hitman Reborn (:

Friday, Before Lunch ==

Hibari was patrolling down the hallways, and passes by the library. Just then, one of the shelves happen to fall down, since a student was trying to grab a book on the top, but accidently pushed the shelf. The shelf was leaning and started crashing down, right on top of 2 other students. Just then, a girl pushed two of them out of the way with her left arm, and the shelf was falling on to her. Using her right arms, she braced herself, while the shelf brutally hit her arm. The impact was quite big, causing her arms to hit her head, but the shelf did not completely crush her. "Sakura! Are you okay?"
"Yeah, I'm fine," she smiled back.
"Thanks for saving our butts! But may we take you to the infirmary?"
"Yeah! You're injured!" The other one said.
"No thanks Taki and Ryu-kun, I can handle it myself." Sakura smiled again. Taki and Ryu helped bring back up the shelf to its original position, and helped Sakura up. "Well, alright then, we'll see you around." And so Taki and Ryu was leaving the library, but bumped into Hibari, who witnessed the whole scene. "Sumimasen! Sumimasen! Hibari-san!" The two of the said in unison, while bowing 3 times, and walked off. Hibari grunted, but stood there, and kept watching what Sakura was doing. She started stacking the books back on the shelf, carefully looking at the codes to see which ones were place before the others. Sakura, her dark brown lock tied up in a plain ponytail, with two clips splitting her bangs to the side. She didn't look special or pretty. Just plain. With the sight of seeing Sakura stacking the books neatly back on the shelf, Hibari left.

Friday, Lunch ==

Sakura walked into the cafeteria, with two of her friends, Hanami and Kurumi. "Sakura! Your arm's hurt! How bout I'll get lunch for you today? Carrying trays around must hurt your arm!" Hanami offered.
"No thanks, I can handle it."
"Are you sure…?" Kurumi asked, concerned.
"Yeah yeah, you know I'm just very buff like that right?" Sakura winked.
"Okay then," and both of them walked off to get their lunch. But speaking of the truth, Sakura's arm did hurt a lot, and she couldn't lift a dictionary with just one arm. 'I'll just skip lunch today,' Sakura thought. She left the cafeteria, and decided to go on the roof, to breathe in some fresh air. She started going up the stairs, and when she was at the top, she gently placed her hands on the knob, and turned it. Stepping outwards, she could see the blue skies and the clouds, and birds flying. What a beautiful sight. But she also saw someone. It was Hibari-san, lying on the floor, with his arms reaching backwards, tucked under his head. Sakura thought 'Hibari-san must feel wonderful doing this all the time, maybe I should try it too.' Sakura quietly walked towards Hibari, and sat down right next to him. She then laid down, and got into the same position as Hibari. Yes. Hibari was pissed. This herbivore was disturbing his peaceful sleep, (even if she was so very quiet) and moreover, she's lying right next to him. He quickly stood up, and took out his tonfas. "What are you doing here herbivore? Do you know your disturbing my mid-day nap? Now get out of here before I bite you to death." Sakura quickly got up.
"Oh, I'm sorry Hibari-san, I didn't know I was disturbing you. I'll leave then…" Hibari has just realized it was the girl this morning in the library.
"Stop right there. Who do you think you are? Disturbing my sleep, and just running off? I'm going to bite you to death anyways." Hibari brought his tonfa higher, and was going to hit Sakura's right arm.
"Wait!" Sakura awkwardly used her left arm to hold the tonfa. She brought her right arm closer to her chest and said, "Sorry, I really didn't mean to bother you, so may I please go?" Hibari's eyes sharpened, and grabbed Sakura's right arm. "Ow!" She shrieked. It was from this morning's injury.
Hibari lets go of her arm after he hears her piercing scream, and says, "Run, or else I'm going to bite you to death."
"Um.. Thanks Hibari-san," and Sakura treaded off.

Friday afterschool ==

Hibari was patrolling around the school, searching for people who are breaking the rules, by staying late. Ready to bite anyone to death. He sees a classroom door opens, and peeks in to see if there's anyone there. There was. And it was no other person, but Sakura. What was she doing here? Sakura was wiping the chalkboard, erasing the words written in class. Hibari watched her as she wiped the whole board. She then pushed in some chairs that weren't pushed back properly, and cleaned up all the messy paperwork on the tables. Was Sakura staying late to clean up the classroom? Was she supposed to do that? Well, if it's cleaning up, and doing good things for the school, Hibari didn't mind. And so, he stopped watching and kept patrolling.

Friday even later afterschool ==

Hibari was done patrolling, and all students have left. Well, Sakura should of left too. He went to check the classroom Sakura was in once again, and noticed she was still in there! Except, she was sleeping on one of the desks. Hibari frowned, and held out his tonfa's while walking towards the unconscious Sakura. He pointed his tonfa and her neck, and said, "Herbivore, I'm going to bite you to death." With this, Sakura woke up, and jumped in her seat, when she saw Hibari right next to her. She glanced up at the clock and noticed it was already 6pm. "Shit!" she said out loud. Hibari glanced at her with his cold and deadly eyes. "I'm sorry Hibari-san! I didn't know I fell asleep! I'm going to go now! Sumimasen!"
Just as Sakura got up, Hibari said, "Just where do you think your going? Breaking so many rules in one day. I'm going to bite you to death." Upon hearing this, Sakura held onto her right arm, and sweat dropped. Hibari knew her arm was hurt from this morning, trying to save the two students. "Leave, right now, I'll deal with you on Monday," He gave out a yawn.
Upon hearing this, Sakura quickly left the room, but only after saying, "Arigatou!"
