Izaya stumbled forward and glared at Shizuo was he watched the brute force his way through the crowd. He longed to whip out his blade and just hassle Shizuo; make him lose his temper and blow up. But he was still intrigued on how Shizuo acted when not raging like a wild animal.

He followed after Shizuo, pushing his way out of the tunnel and into the open court. He spun around, looking for the actor or the debt collector, but found himself lost in the throng of people.

Gritting his teeth, Izaya risked taking off his shades and pulled down his hood, jumping up and down so he could look over the crowd. He peered through the glass tanks, trying to see past the kelp, coral, rays, and jellies.

"Where the hell…?"

"IZAYAAA!"

The brunette spun around, and saw Shizuo standing stiffly on the other side of the room. The blonde's honey eyes were wide, and the vein in his head was throbbing; his teeth grit with rage and his fists clenched to try and contain it.

Adrenaline pumped through their bodies, as Izaya straightened his back, and sauntered forward, as if caught off guard.

"Ahh, Shizu-chan!~ Fancy meeting you here!" He sang. People parted for him, as if he were a king. It boosted his ego, even though he knew it was simply because people realized that two of the most dangerous people were confined in a tight space.

Surrounded by glass, water, and dangerous animals.

"What the fuck are you doing here?" Shizuo roared, making his way over as Izaya completely encompassed his thoughts. He stormed further, until they were only a few feet from each other. Izaya; hand gripped tight around his blade, ready to attack. Shizuo; hands clenched into tight fists, ready to defend. They stood in a stalemate, neither offering to make the first move.

Shizuo wondered when Izaya would attack.

Izaya wondered if Shizuo would even fight back.

Izaya stepped closer, a small frown on his lips in a mocking manner. It instantly made Shizuo tense up with anger. Perfect.

"I just decided to take a visit to the aquarium, that's all. Is that such a crime?" Izaya cooed, baiting the blonde into a fit of anger.

"Like hell. You're here only to fuck with me!"

Izaya giggled and spun around in a showy manner, "My my! Once again with the "fucking". I've already declined your offer, because I definitely wouldn't want to top such a monster. But, if you insist~"

Shizuo jolted and growled loud enough for the crowd around them to hear.

"YOU SICK PERVERT! THAT'S NOT WHAT I MEANT!"

Izaya merely laughed louder, unable to control his amusement, "Oh, but isn't it?~ Poor little sex-deprived Shizu-chan wants to fool around with something he can't kill?"

"I'll just show you how easy I can kill you!" Shizuo yelled as he reflexively reached out to grab the nearest stop sign. But all his hand met was empty air. He glanced around and took in the surroundings. He had forgotten he was indoors...

"You've been saying that for so long, I'm starting to begin thinking that all this "kill" talk is just your beastly way of flirting with me. Ahh, so brazen!"

"Shut up, shut up, SHUT UP!" Shizuo roared as he trembled, trying to hold in his anger. He just couldn't let himself fight in here. He'd hurt someone beside the flea. "Just...just leave me alone for once!"

"Ahh…always convinced I have an agenda with you."

Shizuo growled and stepped forward, watching as Izaya crouched back a bit. He saw the gleam of the edge of the blade as it peeked out of his pocket.

"Would he really attack me here?"

"Nii-san."

Honey and ruby eyes flickered over, focusing on Kasuka as he stepped into the clearing. He walked up between them, completely unafraid of the two strong forces. He faced Shizuo and gestured with his head toward the door.

"You said we could go shopping."

Shizuo blinked and looked back and forth between Izaya and his brother.

"Oh right…"

He shook his head and unclenched his fists, taking a deep breath. He nodded and turned part way, never letting his peripheral vision leave Izaya, as he talked to his brother.

"Yeah. Sorry about that."

"It's ok."

Kasuka walked out the front doors as people parted for him. Shizuo followed, hands in his pockets as he craved for a smoke. Izaya watched them leave, partially disappointed. He never realized how much he missed their daily chases. It was amazing to Izaya, how Kasuka was able to easily tame the beast that lurked within his brother.

How could someone as apathetic as him control such a strong brute? Was it the lack of care? Or was there a deep amount of compassion that only Shizuo could see?

Perhaps, Shizuo's greatest weakness…was the compassion he received from others.
