Chapter Text
Ever since you had been tasked with walking Cerberus with Beel, you found yourself falling in love with the three headed beast. He loved you too, quite a lot actually. Lucifer was a bit envious, though he would never show it. Sure, Cerberus was his and he listened to him, but it was out of sheer respect. When you were with Cerberus, he turned into a ginormous three headed puppy. It didn’t bother Lucifer too much though, after all, you had a strong effect on everyone you met and Cerberus was no exception. Lucifer actually enjoyed watching how he became so tame around you. You had somehow managed to capture the hearts of both the beast and the master.
You usually played with Cerberus while accompanied by Lucifer, but today he was particularly busy. You still wanted to see your favorite beast though, so you made your way into the backyard. There he was, curled up and dozing. All three heads popped up when he heard you open the door. You grinned as he came bounding toward you and skidded to a stop. His heads bowed so you could scratch his ears, and pretty soon he was riled up and ready to play.
You weren’t actually strong enough to throw any of his toys (you had insisted that Lucifer buy him some toys, the poor thing was overworked with no way to unwind), so you just ran around the yard for a bit while he chased you.
As you were jogging around and giggling, Cerberus in tow, you lost your footing and fell face first into the ground, your head bouncing upward a little before landing. Your vision went black for a few moments as you laid there. Cerberus had stopped running immediately and walked to your side, one of his heads sniffing at you and whining. Your eyelids fluttered as you tried to regain your senses. You reached out to the head that was bowed in front of you and placed your palm between his eyes, letting him know you were alright. You allowed yourself a few more moments to catch your breath before pulling yourself to your feet. The world was practically spinning as you stepped slowly toward the door to go back inside the House of Lamentation. Cerberus padded cautiously behind you, still whining a little.
You finally reached the door and pushed it open, leaning into it a little so you could catch your breath. You didn’t particularly want to go to Lucifer’s study because he was working, but you had to admit you were getting a little scared of how you were feeling. The dizziness hadn’t subsided and your stomach was turning. It was also hard for you to even focus your eyes on anything. It took all of your concentration to even remember where the study was, and when you found yourself at the door you didn’t knock like you usually would, you just leaned into the door as you turned the knob, practically collapsing against it.
Lucifer was bent over paperwork, per usual, when he heard the door click open. He was irritated at first, who was rude enough to come in without knocking? He looked up and there you were, clutching the door knob and slowly sinking to the ground, blood dripping out of your nose. He rushed over to aid you immediately, helping you back to your feet and walking you to the couch.
“Oh, Luci. I was looking for you.” For a moment, he thought someone might have placed a curse on you, but he looked into your eyes and noted the difference in pupil sizes. ‘I’ve read about this somewhere...head trauma?’ After the incident with Belphegor, Lucifer had taken it upon himself to learn a little more about human injuries.
“Y/N...what happened? Did you hit your head?” Lucifer had you seated in his lap, trying to keep you sitting upright. He grabbed a tissue from the end table and held it up to your bloodied nose.
“Mmm...can I sleep?” You leaned up against his shoulder and closed your eyes. Lucifer gently lifted your head and rubbed a thumb against your cheek.
“No, darling, not right now. Do you remember what happened?” It was becoming clearer that he probably wasn’t going to get any answers out of you, which had him quite worried.
“What happened? Mammon spilled his coffee on you and you got mad at him,” you dralled. Your voice was much slower than usual. Lucifer shook his head.
“That was this morning, love. What happened before you came here?”
“Before I came where? I always sleep in here.” Lucifer’s lips pressed into a tight line.
“Okay, love, we’re going to the human world for a while to get you some help.” He lifted you and readied himself for the teleport. He didn’t want to use any magic for fear of harming you further.
In the blink of an eye, the two of you were standing outside of the hospital in your hometown, and Lucifer was moving quickly toward the nearest staff member.
You looked around, puzzled by your surroundings. Why were you in a hospital? Weren’t you just at breakfast? You looked up, staring blankly at Lucifer’s jawline. Why was he holding you? Did you fall asleep?
Lucifer’s mere presence intimidated the nurse he was talking to. The nurse stumbled over her words, trying to explain that ‘no, there are no beds available at the moment’, but instead what came out was, ‘yes, of course we have a free bed, one moment please’. She covered her mouth, startled at what she just said. Lucifer gave her a smug smile before she ran off, getting a room prepared. The man who had burned his finger on the fryer at work was just going to have to wait.
“Luci...” you tugged at his cloak and he looked down at you. “Where are we?” His brow furrowed.
“We’re at a hospital, in the human realm. You’ve injured yourself, darling.” You just blinked at him in response, not quite understanding.
“Y/N?” Someone’s voice called. You went to respond, but Lucifer started walking toward the voice. Once he had stopped, he was laying you down on a white bed and covering you with a particularly itchy blanket.
After a few extremely long hours and a CT scan, you were admitted to the hospital for overnight monitoring. They transported you to your own room and settled you in before leaving you and Lucifer alone. Some of your senses were starting to return to you, and you weren’t quite as confused about where you were and why you were there.
“Luci, you don’t need to stay with me. I know you’re busy.” You played with the hem of the provided blanket as you looked into your lap.
“Y/N. I may be busy, but you’re more important to me than my work.” His hand rested on your thigh, causing you to look up at him. You pouted a little.
“At least go home and get some rest. That chair can’t be very comfortable.” Lucifer was silent for a few moments.
“...alright,” he sighed, standing and placing a kiss to your forehead. “I’ll be back in a few hours, love.” You smiled, happy with yourself for how easily you had gotten him to resign. What you didn’t know is that he had other plans that didn’t involve resting.
After a couple of hours had passed, Lucifer was back by your side once more with a stack of paperwork in his lap and a coffee cup next to him. You were asleep when he returned, so he just silently worked, sneaking a peek at you every once in a while to make sure you were still okay.
As you started to stir, you were a little confused as to whose bed you were in, but soon remembered where you were. Your eyes fluttered open and you were laying on your side facing Lucifer, who was concentrated on writing. The next thing you noticed was that your arms were wrapped around something, and when you looked down you smiled. A little black dog plushie was pressed into your chest.
“...looks like you didn’t go home and rest,” you said quietly. Lucifer’s eyes shot up and he leaned forward, all of his attention now on you. He smirked.
“You didn’t actually think I would give up that easily, did you?” You smiled a little and rolled your eyes, holding the stuffed dog up to show him.
“And where did you get this?”
Lucifer blushed, if only slightly, before speaking, “well, you looked like you needed something to hold onto, and I certainly wasn’t going to get in that bed with you. I purchased it at the ‘gift shop’.” There was something you weren’t expecting. He knew you liked stuffed animals, but he usually teased you about it, calling it ‘childish’. Yet here he was, buying one for you. You smiled softly.
“Thank you, Luci. I really appreciate it.”
“I knew you would,” he said, smiling a bit and taking your hand. “It looks a little like Cerberus, doesn’t it?” Your eyes widened.
“I remember now.” Lucifer sat up a little.
“Remember what, darling?”
“How I hurt my head. I was playing with Cerberus...”
“Y/N,” Lucifer said sternly. “I’ve told you you shouldn’t be out there on your own with him.” You shook your head lightly.
“He didn’t hurt me, Luci. I think I must’ve tripped.” A fuzzy image of the whining beast popped into your head. “He was actually worried about me.” Oh, how you wanted to be home and show your poor puppy you were okay.
Lucifer was a bit taken aback, but then realized he shouldn’t be that surprised. That would explain the message he received from Beelzebub that detailed the odd behavior of the beast when he tried to walk him. He wouldn’t budge, he was just curled up, all three heads whimpering. He must’ve thought he had hurt you in some way. Lucifer sighed.
“Well, there’s going to be absolutely no roughhousing between the two of you when we get back, is that clear?” Though the two of you were dating, at times you felt like Lucifer spoke to you like he was your father.
“Yes, sir,” you said a little mockingly, grinning at him.
“Oh princess, you should watch your tone, or I might have to bend you over my knee--”
“Luci! Stop it,” you blushed.
Lucifer smirked at you, “I’m only teasing darling. You’ll need at least two weeks of recovery before--”
"Lucifer!!!"
