"Let's keep things professional. No need for emotions to be involved, no attachments, anything.. got it?"Levi says with an unreadable expression.

For context, you were meeting with Levi in his quarters to spend the night. It was something you two had done once before, and again now... tonight. You had been with the Scouts Regiment for a few years, but didn't get close to Levi until recently. Well...physically close. He was too closed off. He didn't want anything serious. This relation you two had was purely attraction, that's it. He promised himself he wouldn't care if anything went wrong. People get hurt or die all the time, he cannot risk losing his cool over a girl.

So here he lays in bed, assuring that you understand the conditions before you join him once more.
