DISCLAIMER: I don't own Durarara! or BIGBANG's Hands Up lyrics!

A/N: Inspired by BIGBANG's new EP, Hands Up. Please ignore the translating part; the song is in Japanese, not Korean, so that kind of messed with my storyline a little. I'm not trying to diss BIGBANG in this at all. HUGE Daesung fan right here! ^w^
Mainly fluff and absolutely no plot! Somehow, I imagine Izaya to be very sexy when singing.

Summary: "Shizu-chan, I think this song describes us just perfectly!" "That just makes me hate it even more!" In which a simple catchy song leads to a revelation.

"If we pass by each other on the street,
Act like you didn't see me and go the way you were walking to.
If you keep thinking about our past memories,
I might go look for you secretly."
-BIGBANG, 'Haru Haru'

The song had been a hit in South Korea, where the band had originated in. Its popularity spread to Japan in no time and raged through the radios of the twenty-three Tokyo Wards like wildfire. Ikebukuro was certainly not excluded from this BIGBANG rage and the citizens welcomed the song into their town with open arms, or rather, ears.

The song was catchy but, if heard too many times, was just incessantly irritating. Heiwajima Shizuo was one of those people in 'Bukuro who was fed up with the pop song as well as the teenage girls fawning over the band members. His disdain was clearly emphasized when he and Tom were trying to get a man to pay his debt. The man had already been making (terrible) excuses for not paying up and wasting Tom and Shizuo's time when his cell phone went off and his ringtone was that song. In the end, the man paid his debt after Shizuo crushed the cell phone to bits.

To make matters worse, Celty, who actually liked the band, downloaded a few BIGBANG songs and Shinra, who knew that Shizuo was technologically challenged, changed his ringtone to another but equally irritating BIGBANG song. Poor Shizuo had to resist the urge of crushing his cell phone every time somebody called him.

The worst was his enemy, Orihara Izaya. The stupid flea mocked him for having such a ringtone once. "Oh, Shizu-chan! I wasn't aware you had a thing for Korean boy bands," Izaya drawled when they crossed paths one day and Tom called while Shizuo was attempting to bludgeon him with a vending machine. "You wouldn't happen to like Korean dramas as well, would you?"

"I don't!" Shizuo retorted sharply, throwing the vending machine at the flea.

"You sure, Shizu-chan? They're pretty addicting." Teasingly, Izaya added, "So who's your favorite in BIGBANG?" The question resulted in Shizuo uprooting a stop sign and trying to beat the flea with it.

Laughing like a maniac, Izaya danced around the stop sign, singing, "Hands up high, high and low! Inside out, just one step, two step~!" His voice wasn't actually that bad and he was in pitch, but Shizuo didn't really care if the flea was in pitch at the moment. His only concern was shutting him up via stop sign in the face. "Personally, I like G-Dragon the best. Til next time, Shizu-chan!" Izaya grinned, ducking beneath the stop sign and slipping past Shizuo. Shizuo turned to chase him, but by then, the informant was already gone.

They met again a week later, which was actually much longer than Shizuo expected. Instead of Shizuo finding the informant, it was Izaya, instead, who had found the bartender completely and utterly obliterating a radio to itty bitty fragments.

"I actually like that song, you know," Izaya retorted dryly as he settled himself on top of a convenience store trash can.

"It's a terrible song," Shizuo answered, attempting to suppress his rage long enough to wonder why the informant wasn't trying to provoke him.

"Have you translated the lyrics?" Izaya asked curiously.

Shizuo blinked. The informant was always such a queer little man. One moment, he was trying to torture Shizuo, and then the next, he'd be interested in song lyrics and their translations. "Why would I want to translate a song I don't even like?" the blond questioned seriously. Izaya looked sincerely appalled by his reply and proceeded to stare at him like he was a complete idiot who couldn't appreciate the finer and deeper meanings of a song (which he probably was). "What?" Shizuo demanded, about to lose his temper and go over and get that look off Izaya's face literally.

Izaya snorted and looked away, sensing that Shizuo's already short fuse was dissipating at an alarming rate. "Hands up high, there will never be a time like this again. We don't care about things like the voices around us," he recited. "Shizu-chan, I think this song describes us just perfectly~!" he exclaimed, losing all the seriousness he possessed a few seconds ago.

"That just makes me hate it even more!" Shizuo roared, ripping the trash can out under the informant.

The informant managed to get away in time and looked at Shizuo seriously once again. Waving his hand, he dismissed the violent act. "No, seriously, Shizuo, I think this should be our song."

"I don't want to share a song with you. Especially this one," the bartender said angrily to the dense informant.

"Everybody please don't stop experience that feeling. No matter what happens 'cause we belong together! Everybody please don't stop you got me going crazy!" Izaya sang, with one hand over his heart and the other extended out towards Shizuo as if he were serenading him.

In an attempt to shut him up, Shizuo threw the trash can at Izaya. Much to his surprise, (and Izaya's) the trash can actually hit its mark, effectively pinning the smaller man beneath it. Shizuo stalked over to the trash can and pushed his entire weight into it as if hoping to squish the informant like the bug he really was.

"Ahhhh, Shizu-chan," he whined, "I'll stop singing. Let me up! I won't bother you about this anymore! Promise!" Shizuo frowned, debating whether or not he should let the flea go or crush him now and rid himself of all problems. Izaya panicked momentarily when it seemed that Shizuo was really considering crushing him with sheer strength. "Shizu-chan!"

"I really hate violence," Shizuo muttered, lifting the trash can off the informant. Izaya breathed a sigh of relief as he backed himself into the building wall, setting a distance between himself and Shizuo. His hand reached for his flickblade, preparing to draw it out in case the violent bartender changed his mind. He watched as Shizuo set the trash can back where it was supposed to be and then turned his back to the informant, starting to head home.

"Shizu-chan," Izaya called out dryly, his voice half caught in his throat. Shizuo paused for a second, looking over his shoulder. He pushed his sunglasses up the bridge of his nose and waited for Izaya to speak. The informant approached him slowly and then professed, "I really do think that it could be our song."

"Probably," he answered gruffly, waiting for Izaya to make the first move.

Izaya read the gesture clearly on Shizuo's face and hesitantly reached for the bartender's shoulder. Settling his spidery fingers on the smooth black vest, Izaya reluctantly pulled the blond towards him until their lips touched. Shizuo tensed, surprised that Izaya actually went through with it. He pulled back slightly and in response, Izaya stood on his toes and leaned in, unwilling to break the contact. Boldly, Izaya wrapped his arms around Shizuo's neck to hold him close as the kiss deepened and the heat and passion intensified.

"Now put your hands up!" Izaya said with a Cheshire Cat grin when they parted. "Hey! Ho! Hey! Ho! Hands up high, high and low..."

This time, instead of using a trash can, stop sign or even a vending machine to shut him up, Shizuo pulled Izaya back in for a kiss. "Enough singing," Shizuo said in a low growl against Izaya's lips. "Just because it's our song now doesn't mean I have to like it."

"Fair enough," Izaya moaned softly against him. He reluctantly pulled away, keeping at the most an inch between them. Willing to poke the bear, he asked with half-lidded eyes:

"So, Shizu-chan, who is your favorite in the band, anways?"
