Pairing: Shizuo/Izaya

Prompt: V-Day Shizaya

It is a known fact and well attested by research that before reaching emotional maturity boys often acted with excessive aggression toward their crushes. In stage of development in which liking someone was tantamount to showing weakness it was a coping mechanism. And one that both a certain Heiwajima Shizuo and Orihara Izaya found themselves entrapped in.
They were aware that it was so regarding themselves but remained firmly convinced that the other harbored only deeply seated hostility. Shizuo had almost given up on ever being able to convey his feelings in any way. He was terrified of Izaya's scorn and well-known sharp wit that would make Shizuo's remaining high school days an absolute living hell. But as Valentine's Day drew nearer and he kept spotting girls giggling over Izaya and exchanging chocolate recipes, he decided that he had to say what was so oppressing him even if it killed him. Which might very well happen, whenever Shizuo did as much as think about approaching the topic, he became pale and rather sick. For the time being he decided to keep his distance from Izaya as much as possible while he gathered his thoughts.
Unfortunately that was easier planned than done.
"Shizuo-kun and Izaya-kun are on duty call tomorrow."

Izaya did not sigh but his spirits sank. Tidying up the classroom before and after class was already bad enough as it was but it was ten times worse when Shizuo was involved. Izaya counted himself lucky if a desk did not land on him. He had to wake up earlier, too, but he was fully awake by the time he got to school. After all, he could not afford to be sleepy around Shizuo. Izaya was extra early today, his plan was to get everything done before Shizuo arrived.
To his surprise Izaya found that Shizuo was already hard at work, broom in hand. Izaya knocked at the door.
"Good morning, Shizu-chan."
"Oh, hi."
Shizuo merely glanced at Izaya and resumed staring at the floor that he was industriously cleaning. Izaya was beyond surprised at this. He decided to clean the blackboard erasers since Shizuo was currently moving toward the back of the classroom. Every now and then Izaya stole a brief glance at Shizuo to see if it was still safe or if he should get closer to the door in case things went South. Izaya found himself staring at Shizuo more and more since apparently Shizuo was too busy studying his feet. Izaya wished that he could get around to imparting his feelings but he knew how hopeless and it was. Worse, it was downward dangerous. Izaya could imagine just how angry Shizuo would get and it would result in nothing short of disaster.
It was highly unfortunate that he was stuck liking someone like Heiwajima Shizuo and if Izaya could think himself out of this emotional entanglement, he would gladly have done so. But try as he might to keep in mind that Shizuo was brutish, not particularly bright, borderline insane and clearly beyond hostile towards people in general and Izaya in particular, Izaya could still not bring himself to let go of his emotions.
"I'm done."
Izaya jumped.
"Ah, right. I still need to wash the blackboard."
Shizuo hesitated for a moment.
"I'll do that for you."
"You don't have to…"
"But I'm taller, it's easier for me."
Shizuo proceeded to wipe the black surface with a sponge. He could wipe the entire blackboard without even having to stand on tiptoe.
"Thanks."
"No problem."
Shizuo fidgeted. Both were profoundly relieved when the rest of their classmates arrived.

"Alright, break up in pairs and do stretching exercises. Shizuo-kun, you're with Izaya-kun."
Shizuo nearly panicked. Being around Izaya was enough to unnerve him and make him even more susceptible to bouts of anger; having to actually touch Izaya might unravel Shizuo completely. Izaya was simply terrified of being mangled and immediately tried to talk himself out of this pairing.
"Sensei, can I be paired with Dotachin?"
"You and Shizuo-kun have to work out your issues together."
Shizuo's heartbeat kicked up a few notches. Izaya was wearing a gymn shorts and a shirt, his slender legs seemed most inviting as Izaya sat with his knees parted. Shizuo wanted to both run away and pin him down. Instead he licked his lips nervously and placed his hands on Izaya's slender shoulders.
