Tsuna cursed under his breath, running as fast as his legs would carry him, his breathe coming in short puffs.

He cursed his stupidity. How could he have gotten up an hour late!?! He sighed angrily, quickening his pace, muttering under his breathe.

He let out a sigh of relief when he could see the school in site. Sure, he would be really late, but atleast he would be there. He ran up to the door, throwing it open and running down the halls, towards his second period class.

'Just a bit farther…..' Tsuna thought, he was about to turn the corner that led to his classroom, when he bumped into. He let out a cry of surprise, and expected to feel the pain of falling on the floor, but he never did.

He did, however, feel a hand on his back, keeping him up. He opened his eyes, and they widened in shock realizing who it was.

"H-Hibari-san!" Tsuna cried out, his cheeks heating up in embarrassment. He quickly regained his composure, and bowed. "I-I'm sorry, I wasn't looking where I was going a-and-!" He quickly explained, fearing what Hibari would do to him for even daring to be in his presence. He gulped loudly when Hibari glared at him.

"You're late, and running through the hallways. DO you know the punishment for that, Sawada Tsunayoshi?" Hibari asked, staring down at the obviously frightened boy.

"I-I'm sorry, H-Hibari-san I-I over slept and…" Tsuna stammered, staring at his feet, his shoulders shaking, feeling Hibari's eyes on him.

"No excuses." Hibari said, his face unchanging. "I'll bite you." Hibari said, smirking slightly.

Tsuna gulped slightly, wondering why Hibari had left out the 'to death' part, but honestly too scared to care. He went rigid when Hibari leaned down, face to face with Tsuna. He could feel his face heat up slightly, realizing how close Hibari was. He felt Hibari's fingers touch his chest, and his eyes widened as he felt Hibari slide his hand up Tsuna's neck, holding his chin and tilting it up. He could feel Hibari's breathe on his neck as he leaned down and placed his lips on Tsuna's neck, biting down softly.

Tsuna gasped in shock, his face turning bright red as he felt Hibari's tongue lick off the blood from the newly formed wound, raising his head and licking his lips with a smirk. Tsuna put a hand over his neck. "H-H-Hibari-san…"

Hibari merely turned his back. "Your mine, that mark is proof of that. Anyone who tries to come near you, and I'll bite them to death." And with that, he walked away down the hall.

Tsuna stood there, holding the newly placed love bite, while his cheeks were flushed a healthy shade of red. The events that just took place spinning around in his head. He shakily walked off to class, ignoring his friends concerned questions. The only thing he could think of was the feeling of Hibari's lips.
