"Izaya-kuuuuun!"
Shizuo Heiwajima's yell echoed for blocks, even in the always crowded area of Ikebukuro. He couldn't help himself. Izaya Orihara's very existence was enough to anger the blond haired man. He wasn't a horrible person; he actually hated violence. He just really wanted to kill Izaya. So he picked up a stop sign as though it were nothing more than a leaf and tossed it at Izaya's stupid head.
Izaya (who would argue that his head was far from stupid; in fact, it was much smarter compared to most humans) scurried away with a hearty laugh as if the taller man had told a hilarious joke. "Oh Shizu-chan~"
The chase around Ikebukuro continued for hours. Several lamp posts and signs were no longer rooted to the ground. Shizuo stood in a park panting at Izaya. Why wouldn't the bastard just die already? Letting out a frustrated growl, he picked up a garbage can and threw it at the information broker.
Izaya smirked and dodged it before continuing to run through the busy streets.
Shizuo didn't catch him. He never did.
Days later, Izaya's little sisters were trotting around trying to find Shizuo's brother. Celty and Shinra were at home watching television. Mikado, Anri, and Masaomi were eating hanging out together. Everything in Ikebukuro was peaceful.
"IZAAAAYA-KUUUUUUUUN!"
Except Shizuo was trying to kill Izaya as usual. Breathing heavily, he chased the black haired man down the street. Izaya tossed knives back at the taller man who ended up getting stabbed by a few but took no notice.
At one point, Shizuo managed to get so close to Izaya that their heads were pressed together, With a smirk, the shorter man pressed his lips against Shizuo's in a rough kiss, grabbing a fistful of blond hair. Then he pulled back and ran off, looking pleased with himself. Erika (who was sitting in a van nearby with Walker and Dotachin) let out a squeal of delight.
Shizuo was so stunned that he stood in place and licked his lips. Eventually his senses came back to him and he resumed the chase once again, angrier than ever and muttering "kill, kill, kill" under his breath. Shizuo planned on making sure the bastard suffered a great deal of pain.
Once he kissed him back.
