Darkness isn't the absence of light... it's the absence of you.

It took Iruka a while to find a reason for the sudden darkness in his life every time Kakashi left the house or even the room.
It had started almost right after he moved into the Jounins apartment and Iruka had a hard time pinpointing the cause of it.
He supposed it could be that he was becoming too attached to the guy.
They spent so much time together that every time Kakashi had to go away somewhere or on a mission Iruka felt a bit empty and lost but never before had it felt so completely dark before.
Was this what came with love, from actually being in love with someone?
It hadn't been so dark after his parents had died, and although he missed him when they weren't together it was never this dark when Naruto left and he loved them, they were his family.
Maybe it was something about being in Kakashi's apartment when he wasn't there, even though it was theirs now he wasn't used to being there without him.
He really hoped he wasn't becoming that attached to the guy, I mean Kakashi was going on missions all the time and Iruka just could not bear the darkness every time he left, although it only seemed to stay until Iruka had gone out for some time. He supposed going out and meeting other people helped so every time the darkness became too unbearable that's what he did.
Iruka was deep in thought about those things when Kakashi walked in again and the light came back into his life.
"Maa, I'm sorry Iruka. I guess I'm so used to living here alone that I still turn the light of every time I leave."
