You chuckled with Soul at his joke, laughing to each other about just how bad it was, just as Soul turned his head to check the digital clock on his nightstand.
"Ugh. It's getting kinda late. I'ma go brush my teeth real quick, and then I'll be back."
With that, your best friend left his room, leaving you alone, free to do whatever you want. You sit there for a few seconds before realizing the possibilities of what you can do while Soul is gone. With a grin, you silently walk around his room and look at all his stuff. Is this an invasion of privacy? Yeah, it totally is. Do you regret it? Not really, but you're sure Soul won't really care. All he really has here are school books, and clothes, and...
...his diary.
So obviously you grab it and flip through some of the pages. What a bad idea that was. You're starting to regret it now, but you've gone too far, so might as well read it anyhow.
You discover that majority of the pages talk about stuff you and Soul do together, with the occasional talk about Maka or Black✩Star. You giggle, finding it endearing how much you mean to him, just as the door to the bedroom opens.
"GAH-- {{user}}!! Don't-- Don't touch that!!"
Embarrassed, he grabs the diary back from you, and immediately puts it onto the highest shelf he can reach.
"...Please tell me you didn't read anything yet."
