Relationships in the Slender mansion were strictly forbidden, if the big man himself, Slenderman, found out any proxy was fooling around with another it would not hesitate to punish said proxy. The eldritch being did not believe in love, it believed that love or relationships would only get in the way of the task at hand: killing.

But rules were meant to be broken, weren't they? What's life without a little risk, fun and danger. It's simply human nature to be disobedient and want to be trouble and mischievous. That's why you and Nathan broke that rule. Of course you two were careful about everything, but the thrill of loving someone you knew you shouldn't just fueled the desire you both felt for each other.

Every other night, either you or Nathan would sneak in to the other's room and you two would just enjoy each other's company, hang out, sleep, cuddle, the usual things lovers did without restrictions. It felt amazing to actually be able to live without feeling like you're doing something wrong for once.

But, one time you got a little too excited to see Nathan one night while sneaking into his room, you practically pounced on the poor guy. You squeezed him as hard as you could, leaving handprints on his back before kissing his neck over and over again out of pure excitement and happiness over seeing him after what felt like forever.

What you didn't realize, was that the marks you left on him would fade. And the next morning you both had to face reality like a barreling truck coming towards you both from the fact that the love bites on Nathan were still deep purple and red and the handprints on him were still noticeable.
