A/n: more idol au? Hell yeah. But this time, with a twist.

Hc: you're L's favourite singer. He'd die for you. After a long hiatus, he revives an email from you, asking for permission to use his logo for a secret project.

Going through emails when there's a strange god-like power killing everyone wasn't that fun. Countless police departments asking for updates, the FBI and CIA constantly trying to butt in. But it was necessary in case important evidence as send among the countless other emails. So that's what L, the worlds greatest detective, was doing right now. Scrolling though hundreds of unread emails, checking them and seeing which ones could just be deleted, and which ones were actually important.

It was mainly the FBI, they seemed to want to get involved a lot. And surprisingly a couple of espionage agency's were trying to get in on it too. But L already had spies set aside if he needed them.

It was just scroll and click, scroll and click. He'd been doing it for about five minutes straight now, occasionally picking up his overly sweetened coffee to take a sip from.

That was until an email address caught his eye.

(Y/n)[email protected].

(Y/n) dare. His favourite singer. He knew full well that dare definitely wasn't your real last name, he saw straight though that. But it was a safe choice so no personal information can be leaked or tracked. Upon seeing the email address he almost choked on his coffee, and got mental whiplash.

Why on earth would you need to email him? And when you were on hiatus as well? Nevertheless, he clicked on it, reading the email.

L,

Hey! I know this isn't too formal, and you may not even see this. I'm sure you're busy with case stuff. But I just wanted to ask permission to use your logo in an upcoming music video. Could I get a license? I don't want to infringe any copyright issues. It's totally cool if you don't let me, it's just my next song is basically a Kira diss track and I need the imagery for the MV.

Get back to me if you can, or have someone from your team get back to me. Thank you.

-(y/n).

It was like a massive surge of energy came rushing though his body as his excitement levels went though the roof. A stupidly bright smile plastered on his face. Not only did you contact him, you were on his side! He knew dropping a diss song in Kira could be risky business, but as long as your last name was hidden, and you wore your signature sunglasses, you'd be pretty safe from Kira. Plus, you weren't a criminal, and you technically weren't 'getting in Kira's way'. Just poking a rod at him. You'd be safe with extra security.

Security he was willing to provide if he had too.

The excitement got too much and he tore the charger out of his laptop, picking the computer up and sprinting down the halls to Wataris office where he skidded in and practically kicked in the door.

"WATARI, GET A LICENCE DOCUMENT FOR MY LOGO!" He exclaimed.

The boys caretaker jumped at the sound of L's sudden voice and turned to face him, confused.

"What on earth for?" Watari asked.

"OK SO (Y/N) EMAILED ME AND ASKED IF SHE COULD USE MY LOGO FOR A MUSIC VIDEO BECAUSESHESDROPPINGADISDTRACKONKIRA, AND-" L exclaimed at a million words per second.

"Woah, L, slow down. She emailed you and..?"

"She's dropping a diss track on Kira and wants to use my logo in the MV, and of course I'm saying yes but she needs a licence because of copyright and stuff"

L handed over the laptop and let Watari read the email.

"I'll see what I can do. In the meantime let her know I'll send one through. Be careful having your brand attached to a Kira diss though" Watari said, handing the laptop back.

"YES! Thanks! Oh my god I've gotta email back, ohmygod I'm actually talking to her!"

A few days passed the copyright had been sorted. L re-wrote that email a thousand times trying to get it right. He wanted to mention he's been a fan since your debut, but didn't want to sound creepy. So that email got scrapped and rewritten thousands of times before he sent the final version though.

It was the end of the week, the taskforce were finishing up the weeks work downstairs. L was once again going through emails, when a notification popped up that (y/n)dareoffical posted a new video. Almost getting the same mental whiplash, he smashed the notification like lighting. The page popped up on his screen and he read the title.

(Y/n) Dare - Team L (offical video)

Before he could even react to the title, the video loaded and his logo he'd so generously let you use popped up in his screen, music starting to play and visuals looking amazing.

The rest of taskforce was silent as they worked until there was a loud noise from upstairs that broke the silence.

"SHE NAMED HER FUCKING SONG AFTER ME HOLY SHIT"

The taskforce exchanged confused glances. L could speak above room level?

"Ah, the music video must have dropped" Watari muttered, listening to his foster son freaking out a few floors up.

The taskforce just awkwardly went back to work and didn't question it as L was busy getting all emotional upstairs watching you sing about how L was the true justice against Kira's ideals.

The music video was set up like L and Kira were two rivalling kingdoms, and you lead the army from L's kingdom to burn down Kira's kingdom as we watched in a fancy cloak and crown from the top of the castle. Watching as Kira's kingdom was engulfed in flames. The lyrics were a mix of 'L's an angel fallen from the heavens' and 'fuck you Kira, stop banging Shinigami to gain power and ruin people's lives.'

L had never received so much praise before. Having his favourite person sing the words 'like an angel fallen down, he saves those who need it most, he saved me' about him made him feel so honoured. He felt like he'd accomplished something major.

He was already I love with you, but now he was head over heels.

He sat there in awe for a good ten minutes after the video ended, letting everything sink in. But he was snapped out of that daze by dinging at his computer.
