(A Stalker!Y/N X Nightmare. Requested by Unamzi! Thank you! <33)

Tw: Stalking/Obsessive Behavior and My Simp Brain when within 50 miles of Nightmare <3

Your heart thuds heavily in your chest with anticipation. Today's the day the love of your life lets you into his home. 

Well, not quite. You were following him home last night, ensuring he made it home safely and slept well when you came across a faulty lock on one of the many doors to his mansion. Seizing your opportunity, you waited there all night, equipped with some overnight snacks and your favorite tunes as you camped near his nice thorny bushes. 

Early in the morning, you hear him inside his home, and peer through the window. There he is, your Nightmare, sitting at the table, scrolling through his phone. He sits in that cute hunched way you've come to adore, tentacles flipping absently at his back before he rises and stretches, heading for the front door. 

You rush to the side of the house and watch him exit, pacing absentmindedly down the long driveway until he stops, snaps, and disappears. 

"Goodbye my love.~" You coo, grinning wide before carefully undoing the lock on the faulty door, slipping inside and shutting it behind you. "Hello new home." 

All at once, different sensations attack your senses. 

The sheer size of the room you have entered has you gaping, not to mention the beautifully crafted interior, black with subtle blues and purples. The scent of smoke and a twinge of fried food lingering in the air. The way the air seems to cling lightly to your every hair. 

Shell-shocked, you collapse onto your rear, marveling at it all as a giddy feeling rises within you. It's better than you imagined! This place is awesome! 

Getting up, you pull out your camera and start snapping various photos. The living room, the kitchen, the cleaning closet, several guest rooms, the staircase...etc. Captured by your camera for you to keep forever. 

While you sift through already existing snapshots, a diabolical thought slams into your brain like a train.

What... WHAT IF YOU WENT INTO HIS ROOM??

Ecstatic, you race up the stairs, eagerly throwing open every door until you find the room you know is the one. It takes a minute, and you nearly get impatient, but when you fling open a large black door, your mouth drops open.

A large, plush bed sits in the center of the room, cyan lava lamps along the walls and furniture. A pristine wardrobe against the wall, a black-bear hide adorning the floor. You're sure there are more beautiful intricacies, but those ones are the only ones you capture in the low light of the room. 

In a trance-like state, you waltz in, enamored with the room you stand in. You take so many pictures. One for every lovesick beat of your heart. 

In a bout of indulgence, you sit—no lay on his bed. Relish in the scent of it. The feel of soft blankets and a springy mattress cushioning you. It's heavenly, so heavenly—

You feel your eyelids start to droop and shoot up, alert. You stayed up all night last night, just for this opportunity. You couldn't fall asleep and waste it! No way!

But... you'd already seen most of the house, and how many people ever got to sleep in their soulmate's bed? When would the chance ever arise for you again? Besides, you're tired. Work done, reward earned. 

Just to be safe, you set a thirty minute timer on your phone so you can wake up. Then, with a slight touch of hesitance, you lay down and get comfortable, letting your eyes slip closed and your muscles relax. 

Your dreams are filled with fantasies in which Nightmare treats you as you wish to treat him, like his everything. The two of you living in this very mansion, the mansion you sleep in. 

And you sleep, right through your alarm. 

It's when the sun starts to sink below the horizon that you wake up, bright eyed and bushy tailed. You sit up and stretch, satisfied with the noises that come from your spine and shoulders. A glance at your phone reveals that it's about six o'clock. 

A glance at your phone reveals that it's about six o'clock.

"Shit!" You hiss, scrambling to collect your things. You've overstayed your welcome! If your beloved sees you in here—

The lava lamps cut off, bathing the room in thick, black darkness. 

You feel your blood run cold and fumble for your flashlight, but you're barely able to move before hands, cold and hard snatch your wrists and pin them behind your back, pushing you face down onto the bed you haven't fully recovered from sleeping in. 

Squealing, you kick out, eyes shut tight in your attempts to escape your assailant. Your feet connect with nothing, and thick, slimy appendages pin those too. 

Your eyes pop open, glancing behind you to see your one and only looming threateningly over you, cyan eye piercing through the heavy blackness.

"What have we here?" He croons, wicked grin stretched far across his face. You watch, heart racing and eyes wide as he brings a tentacle up to stroke along your jawline. Then, in one swift motion, he swaps his tentacles for his hands, allowing the appendages to pin you while his fingers tap along your shoulders. 

"How do you sneak in, little rat?" 

The sound of his voice so close to you sends shivers down your spine. The first few times you try to form words, you fail, still absolutely awestruck to find him in your presence. 

"I-I-I..." You stutter, breathless. "I c-came in through a bad door. I-I just wanted to s-see you." 

He leans back, presence leaving you for a moment before he cranes back over you, and you feel his breath tickle the hairs of your neck. "Me?" The single word is more than enough invitation for explanation, and you blush with the revelation of your infatuation.

"I..." You gulp down your nerves, squinting before balling your fists. "I love you Nightmare!" 

Silence.

For a few minutes, all you hear is the pounding of your heart, which may as well explode right here in your chest. 

"Really?" He asks, a fat, cold blob of slime falling onto your neck. The sensation gives you full body chills. "Smells more like lust to me, obsession even." 

It takes a moment for the accusation to sink in, and you let out a pitiful, desperate noise. "W-What? No! No Nightmare I'm in love with you!" Tears prick the corners of you eyes. 

"How often do lovers break into each other's houses huh?" He sighs onto your nape, making your fingers clench. "Or watch each other from the bushes for months on end?" 

That accusation takes no time to sink in, your eyes widening as you look him dead in his cyan pupil. 

"Y-You knew about that?" There's a tone twinge of hurt that comes with it. Embarrassment, but the bitter kind. When everyone's laughing at you and you're not. "I...I..." 

"Yeah." He says lowly. "You should probably stop, honestly. No way it's good for you." He mutters, fingers dancing along your shoulders as his teeth lightly graze your neck, leaving a thin layer of slime that you very much feel. 

"It's one-sided, honestly. I think I'll have to move so you won't know where I live anymore." His voice sends vibrations into your head as he trails up your neck, across your jaw, and eventually rests on your cheek, simply breathing through his teeth. "Goodbye, I guess." 

"WAIT-!" You yell, frantic, thrashing beneath him. "I-I can be better! We can start over!" You feel him lighten, leaving your back, leaving your face. Leaving you empty. 

"Please!" You flip over and sit up on your rear. "I can-!" 

The lava lamps flicker back on, revealing you in an empty room. 

A lot of feelings clash inside you at once, but the most prominent one?

Heartbreak.
