Un-un-undead (Renhyuck)

Chapter 1 + trigger warnings

For those who dont know what pet sematary is: it's from the novel by Stephen King (by the name "Pet Sematary" go read it cos it's really good).
The sematary was a place where people would bury dead bodies to be resurrected, but they would come back basically deranged, smelling like rotting flesh and murderous. They would know information that they would never be able to physically know. Fyi in the OG story, people were only buried once in the sematary (not repeatedly).

Trigger warnings: murder, graphic depiction of violence, body horror, poisoning, strangling/hanging, implied suicide, mentioned parent death, mention of guns, mention of insects (maggots and ants), mentioned past bullying. 

If you're uncomfortable with any of these please don't read. You've been warned.

The first time Renjun came back, he gave a tilted smile to Donghyuck. Soon after, he was wrapped in a hug and Donghyuck pulled away with a brushing of dirt across his shoulder.

"It worked what the fuck," Donghyuck murmured under his breath, an equally wide smile playing at his lips. His eyes grazed over the marks around Renjun's neck, now only roughly covered by his red, woolen scarf draped around his shoulders. Streaks of what vaguely resembled stretch marks hung like christmas lights towards the top of his neck- the base of where his head started- followed by a darker ring of bruises near the bottom. They extended to the backside of his neck, with the ring expanding there into a flower's bloom. On top of all of this, there was a waft of a forest, mossy smell. Neither unpleasant, nor particularly pleasant.

Renjun also hadn't been found blindfolded when he died; Donghyuck didn't think that the dullness of his eyes were from bruising, necessarily.

"So it did. I figured I'd be safe at your place for now." Same voice, same warm, honey, Renjun voice. Same tilted smile.

"Yeah...yeah, you're safe here. No one can...can hurt you now."

"Other than you," Renjun answered, taking his scarf off and hanging it up behind the door. Now the halo of blotchiness was displayed in all its glory, top of the neck down to near his shoulders. His smile was wiped, replaced with his usual neutral expression- that Donghyuck so missed seeing.

He laughed, taking Renjun's dry hand in his own and pressing a kiss onto the back of it.

Sunlight peeped through between Donghyuck's curtains bright and early the next morning. He stretched.

"Breakfast is done," Renjun's voice came from his right side, firm and satisfied. He wore the clothes Donghyuck had left on his bed in the spare room- they still fit like they used to. A faint scent of shampoo came from his hair as he leaned down to rip the sheets off with a laugh, although the forestry scent from yesterday was still overpowering. Though despite being only half awake, Donghyuck noticed the way his gaze unfocused for a second, to look directly at the sunlight, unblinking. Only for a split second, then the old giggle was back and he was being pulled out of bed.

"Cereal and coffee, come on," Renjun's nails dug into the flesh of Donghyuck's arm, imprinting crescent moons. There was no sign of the dirt from yesterday, in fact his nails had been trimmed. Despite this, even a half-awake Donghyuck could smell the dirt, the soaked ground. He resisted from Renjun's tug for a second, and tentatively ran his fingers through a tuft of hair, to which Renjun gave the same grin from yesterday, copied and pasted. Practiced. The hair felt as smoothly as he'd expected, not even with a fleck of sand or soil to his touch. Satisfied, he let himself be pulled along again, to Renjun's delight- perhaps the dirt had made itself a part of him instead.

Which was why not a spot of fear passed over Donghyuck when Renjun was resting his head on his tummy later that afternoon, whilst he wore his one and only white shirt.

"Renjun," he tested the name quietly, though loud enough for him to hear. There wasn't a twitch. "Renjun..." he murmured again, rolling the name over his tongue again and playing with Renjun's hair again. And this time, the person in question opened an eye, staring straight back at him. Funny; Renjun had never been able to wink properly.

"Yes?"

"Do you remember anything?" His eyes glazed for a few seconds this time, longer than the first time, in which his lips curved into a pretty smile once again. A tinge of blood red spread to the white of his eye, and stayed there. Then, he re-positioned so he was sitting next to Donghyuck with an arm slung around his neck.

"I remember when you lied to me, three years ago, that you had to be home only by midnight. You didn't have a curfew back then," Renjun said with no traceable emotion. If he were honest, even Donghyuck couldn't remember such an arbitrary event. All the same, he let out a tense giggle.

"When the hell was that?"

"One of your first parties. You were scared. Although-" Renjun cast a glance to his scarf, still hanging at the door, "-maybe that was a good thing. Your girlfriend at the time cheated on you at that party." Donghyuck shot up at that, hearing a faint crack from Renjun's elbow as he jerked it away from his neck. His hand was beginning to tickle the hairs there, though his fingers were starting to feel more like claws by the second.

"Why didn't you tell me?"

"I didn't know," Renjun said, his hand still by his neck. It started to stray to his cheek, absent-mindedly. "She didn't tell anyone." His finger lightly traced in a figure of eight around his lower jaw.

"Then how do you know?" A shrug. Donghyuck sighed, attempting to settle himself back to his original position.

"I only found out a year after that. I...don't think I even told you why we broke u-"
