Whammy's best hacker ( L x oc )

what happens what L hits a dead end in the hacking department. He calls over the one person that could help him, someone from whammy's one of the only people who knows his real name 7.
7 Is the worlds greatest hacker. no one has ever seen 7's face only a picture of the number 7, and a edited voice but L has seen 7's face and heard 7's voice.
And he knows that 7 is a women, and she is like him in a lot of ways and is his childhood friend but had a fallout a few years ago.
So what will he do to get her to come to the investigation and maybe say...How he really feels about her.

I own none of the characters except Yuki or pictures unless I say I do.

Comment the anime to the reference that I make, all anime references I make I will underline.
