Imbrication

Part I -- Demesne

Beep, beep, beep, beep, bee--clunk--!
Rei slammed his hand on his alarm clock to turn it off. First day back to high school. First day of being a second year student at Sakura High. Another year, another Hell, thought Rei. First year is when all of the students find old friends, make new friends, form their groups, and and push away the undesirables. Rei was always alone. Always has been. Both at school and at home. It's okay though, being alone is much better than the drama and betrayal that comes with being around others.
Already, Rei has showered and has dressed himself in his school uniform. Similar to that of a delinquent, Rei's buttons were undone, his shirt was untucked and falling loosely past his waistline, and his tie was barely on spilling forward down his chest.
Grabbing his bag and a piece of bread for breakfast, Rei ran to school, which was located right down his street.

BEEEEEEEEEEEEEEP!!!

"Phew... just in time!" Rei breathed a sigh a relief as he sat down in his homeroom.
"Hey, Kataro! Welcome back, eh, bro?" Rei looked up only to scowl at what he saw. Great. Rei groaned in his head. He's here...

"Good morning, class. I am your new homeroom teacher." Rei's thoughts were disrupted by a large, buff, muscular man walking into the room. Wow.
"My name is Mr. Onizuka," he announced. While he was talking, his eyes fell on Rei in a scrutinizing way, looking very interested. He smiled a cute, eye-wrinkling smile. Despite that, he didn't look a day over eighteen years of age. Rei blushed.

A girl named Chizuru raised her hand, "Onizuka-sensei!"
"Yes?"
"How old are you?"
"Oh, uh, well, I am 22. Why do you ask?"
"Do you have a girlfri--?"
Rei rolled his eyes at the girls obsessing over the new teacher. Even he, though, sat enamoured with Mr. Onizuka, as well. What he didn't notice was how quiet the normally-loud Kataro had become, watching Rei with intent eyes.
