Hey everyone. I've had this idea for an oneshot since forever. I got the idea off of the episode Badass Dude when Shizuo was at Shinra's and was trying to throw that…I think it was a table, at Izaya going "You're dead, you're dead, you're so freakin' dead". I wrote a story around that particular clip.

I do not own Drrr.

Enjoy.

To most people it would have seemed normal. Shizuo trying to kill Izaya because Izaya pissed him off, but to others who knew him, something was up.

Generally when Shizuo tries to kill Izaya it's for a reason everyone already knows. He doesn't usually show up at Shinra's and randomly try to kill him. And though Izaya usually has that smirk plastered on his face, it usually isn't a big as it was that day.

This time he had truly done something that Shizuo would never forgive…

Shikyo Tenshi had known Shizuo Heiwajima since grade school. She was one of the few people who weren't afraid of him. She was his best friend and one of the people who could calm him down. Throughout middle school they remained friends, but in highschool they stepped up and started dating. Things were going pretty well for them, until Shizuo did something unforgivable in Shikyo's eyes.

Shikyo and Shizuo had been renting an apartment together. Shikyo had something to do after school so she was late in coming home one night. She had been about to open the door when she heard voices on the other side of the door. It was Shizuo's, and another girl's. Shikyo quietly crept over to the window and looked inside just in time to see the girl throw herself at Shizuo. Shikyo would have known the girl had forced herself on him and let it go, however, Shizuo kissed her back.

Shikyo quietly crept away from the window and ran to Shinra's. He look surprised to see her there, and was even more surprised when she wrapped her arms around him and started crying while relaying the events she had just seen.

It was a few hours later that Shizuo came and knocked on Shinra's door. When he asked if Shikyo was there Celty intervened. She typed something on her PDA and held it up for Shizuo. 'She's staying here tonight, if you're lucky she might talk to you tomorrow.'

He looked surprised but just nodded and left. Shikyo sat on Shinra's couch with her knees pulled up against her chest. Celty sat next to her. 'What are you going to do?'

"I don't know Celty, I really don't."

A few days later Shikyo and Shizuo still weren't talking. Shikyo was going to Shinra's through a shortcut in a back alley when someone grabbed her from behind. She went to scream when they put a hand over her mouth. She flung her arm back and her fist made contact with their face. They let go but grabbed her wrist with one hand so she still couldn't run. She turned around to see Izaya Orihara holding his eye.

"Damn woman, I didn't know you could punch that hard."

"What the hell do you want Orihara." She hissed trying to pull her arm free.

"Aw, now is that any way to greet me Shi-chan?"

"Don't call me that Izaya."

"Oh look you do know my first name."

"I'll ask again. What do you want?"

"To see if you would help me with something."

"Why would I do that?"

"Because you could get back at Shizu-chan."

"…I'm listening."

He smirked grabbed her other wrist and pushed her into the wall behind her. "Do to him what he did to you." Izaya whispered into her ear.

"What are you talking about?" He asked struggling to get out of his grasp.

"Cheat on him with me. Think about it, I get to piss him off some more, and you get him back."

"I'm not going to be your play thing Orihara."

"I'm not saying you have to be. I would let you set the boundaries. Hide it all you want Shikyo, I can see how much you want to get him back."

She looked at him. "I get to set the boundaries?" He nodded. "Okay Orihara, but only until Shizuo finds out or catches us."

"Good to see you're on my side Shi-chan."

"But here's my boundary Orihara. No obvious marks, and no sex."

"Aw, come on Shi-chan you take the fun out of things."

"I told you I'm not going to be your play thing."

"Fine, for now, but you might just change your mind before this is over."

"You're sick Orihara."

"I've been called much worse Shi-chan."

"And stop calling me that."

"Sorry Shi-chan, that's one thing I won't agree to."

She growled. "Did you just growl at me?" He asked smirking. He let go of one of her wrists and cupped her chin making her look at him. "I think I'm going to have fun with this Shi-chan." He leaned and kissed her before pulling back and walking away. "See you later Shi-chan, don't let Shizu-chan get to you too much." He said leaving a very shocked Shikyo behind.

Izaya and Shikyo began to have their secret meetings while Shizuo remained in the dark. He and Shikyo began to go out again after he apologized about five hundred times saying it had been a huge mistake and that he would have told her even if she hadn't seen. Of course she didn't believe that last part.

Shizuo never seemed to notice the marks Izaya did leave behind. That or he didn't say anything about it. A couple months after she and Shizuo began dating again Izaya noticed a change in her. She started letting him go a little further each time and eventually he wanted to know what was up.

They were at Izaya's apartment. Izaya had her pinned against his couch his lips against her neck. He started trailing down further and he heard her nails scratch against the leather but she didn't try to stop him this time. He sat up and looked at her.

"Okay that's it. What's going on, since a month ago you threw your boundaries out the window."

"It's none of your business Izaya. Something happened that's all."

Realization crossed Izaya's features. "There was a reason you said no sex, wasn't there Shi-chan?" He said pinning her back down and looking her in the eye."

"Izaya…"

"I can't believe I didn't realize it. You were still a virgin, weren't you?"

"Yeah I was, what of it Izaya."

He smirked again. "You said, yeah I was. So you aren't anymore. I knew you were acting different."

"Are we going to finish this or not?"

He smirked and pressed his lips against hers harder than usual. He ran his tongue along her bottom lip asking for access. Shikyo decided to mess with him a bit and kept her lips firmly shut. He growled and moved his hands up her shirt. She gasped and he took the opportunity to slip his tongue into her mouth.

She moved her hands down to the bottom of his shirt and began to pull upward. He broke the kiss of long enough for her to pull it up over his head. She pulled him back to her and reconnected their lips. Her hands traced patterns over his abs. She smirked into the kiss when she felt his muscles tense under her touch. She ran her thumb along the hem of his pants and he growled. She pulled away.

"What's the matter Izaya?" She asked repeating the action.

He grabbed her wrist. "Don't mess with me Shikyo." He growled.

"Or what Izaya?"

He pushed her down with his body so his chest was against hers. "I'll do something you won't like."

"You have yet to find what really sets me off Izaya. There's nothing you can do that I won't like."

He leaned down and bit the junction where her shoulder and neck met. She gasped and gripped the side of the couch. "You like pain." He smirked.

"You knew…" She breathed.

"I noticed the harder I bit the louder your moans were."

"Are you going to finish this?"

"Gladly," He said pulling her shirt off and latching him mouth back on her skin...

It was a few weeks later that Shizuo found out.

Shikyo was in the bathroom looking at her shirtless reflection. She looked at the marks and bruises that were on her upper body.

"Damn it Izaya," She muttered quietly. "You went overboard." She pulled her shirt back on and went out to her and Shizuo's bedroom.

"Shikyo, are you okay you're limping." Shizuo said.

"I'm fine, I tripped earlier." She said.

"Actually now that I think about it you've been acting kind of strange lately."

"It's nothing Shizuo."

"Really?" He grabbed her arm and she winced. He pulled her sleeve up revealing more bruises. "What happened?"

"I..."

"Don't lie to me Shikyo, I saw you with Izaya."

Shikyo's eyes widened. "Shizuo I..."

"And I made that up, but apparently it's true."

"How did you..."

"I had a feeling, Izaya seemed too happy lately."

"Damn it," She muttered.

"You lied to me."

"I wanted to stop with Izaya after you apologized but..."

"But what Shikyo?"

"You won't like the answer."

"I can't get anymore pissed than I am right now."

"But I developed feelings for him Shizuo!"

Shizuo froze before heading towards the door. "Shizuo?"

"I'll be back later." He said slamming the door behind him. Shikyo sank against the wall and cried.

Izaya was at Shinra's. There was a knock on the door and Shinra went to open it.

"Oh Shizuo, what a coincidence, Izaya's here too."

"IIIIIIZZZZAAAAAYYYYYYYAAAAAA!" Shizuo picked up a table and attempted to throw it a Izaya while Shinra and Celty held him back. "You're dead, you're dead, you're so freakin' dead."

"S-shizuo cal-calm down!" Shinra said.

"Don't tell me to calm down he..." Shizuo stopped. "You know what...forget it."

"Shizuo?"

"Don't worry about it." He said turning to leave. "Mark my words Izaya I will kill you." He said shutting the door.

Shikyo stayed with Shizuo until she got her own appartment.
