A/N: This will be a collection of short stories about Deckerstar. Probably mostly fluff and some hurt/comfort, but maybe I will also add other stories. Tags might change depending on that. I hope you enjoy reading it!

When Lucifer stepped out of the elevator he was greeted with a sight that he didn't expect.

The Detective was half sitting, half lying on his couch, with her eyes closed. Several work-related papers and photos were lying on the table in front of her, neatly arranged like she always did when she was working on a case. She was still holding one photo in her hand—it seemed like she had fallen asleep while thinking about the case.

It was late already—long past midnight—and Lucifer just came back from dealing with some issues at LUX. He had told the Detective in the afternoon that he couldn't make it this evening so she wouldn't wait for him. What he didn't expect was that she would still come to the penthouse.

Lucifer looked at her with a loving smile. Her presence alone was something that made him truly happy, something he could only hope for a few weeks ago when he was still in Hell.

And even now he sometimes couldn't believe that this was reality. That he could be at her side again, and even more, that they were finally a couple. After so many years of them going back and forth, it was something he still needed time to fully realize it.

A light breeze interrupted his thoughts and Lucifer noticed that the window was still open, making the inside of the penthouse a little cold. Without making any sounds, he closed the window, then went to the bedroom and came back with a blanket. He didn't want to wake up the Detective but he also didn't want her to catch a cold. He carefully covered her with the blanket, then kissed her softly on the forehead.

"Sweet dreams, love," he whispered.

She smiled in her sleep, a sight that made Lucifer feel warm inside. He felt truly blessed to have such an amazing person by his side. And he would do anything to protect her, be it from celestial dangers or just from a simple cold.

He kept watching the Detective for a little while longer, then he started going to his bedroom.

"Lucifer?" The Detective's voice behind him was sleepy.

Lucifer turned around. "I'm sorry, did I wake you up?"

"I was waiting for you." She smiled at him.

"You didn't have to. I told you it would get late."

"But I wanted to."

Lucifer smiled and went back to the couch. The Detective lifted the blanket as an invitation to join her, something he couldn't say no to. He sat down next to her and kissed her, something he could never get enough of. Then he wrapped her arms around her and held her close to him.

"How was the evening at LUX?" she asked with her head leaning on his chest.

"A little annoying," he replied. "Amenadiel changed some things when he was running LUX and now there's an annoying group of people who think they own the place and can do just anything they want."

"Doesn't sound like something you couldn't deal with though."

"Of course not. And it was fun to see how fast they could leave the place." Lucifer grinned. "I think I was quite convincing."

The Detective chuckled. "I can imagine. Too bad I missed it."

"How was your evening? Why did you work?"

"Well, I thought I could do something useful while waiting for you." She pointed to the table. "And I think I found some new clues."

"You're amazing, Detective."

Moments like these were still very special for Lucifer. Just the two of them, spending time together, enjoying each other's company, and knowing that they were finally a couple. It was the best feeling he could think of.

"Shall we go to bed?" he asked.

The Detective didn't reply. She had fallen asleep again and all that Lucifer could hear was her steady breathing. It was very late, after all.

This is also fine, he thought.

Then he closed his eyes and kept thinking about her until he drifted off to sleep as well.
