Diavolo let himself into his boyfriend's office to check on him. Lucifer may have gotten better at managing his sleep schedule since getting together with Lord Diavolo, but he will never prioritize sleep over work. Lucifer sat at his desk, mindlessly humming a simple tune.

He must not have noticed Diavolo enter, because he didn't stop. 'Well I'm not going to stop him,' Diavolo thought to himself. He closed the door as softly as he could behind him, and leaned against the doorway, just watching as Lucifer went through the papers on his desk. The tune was low, without many high notes. It sounded like a composed song, with repeating chords and melodies. Lucifer signed papers in time with the song, and Diavolo felt mesmerized at the scene. After a few minutes of just watching, the song ended. Before Lucifer could start a new one or hum that one again, Diavolo cleared his throat. Lucifer looked up from his work with a start. His eyes were wide until he recognized the red mop of hair on the elder's head.

His demeanor softened as he asked, "How long were you standing there?"

"Long enough to hear the beautiful song you were humming. Is it anything special?" Diavolo walked behind Lucifer to put his hands around his boyfriend's shoulders.

"Just an old tune."

"May I ask more?' Diavolo had been around Lucifer long enough to know to ask about things like these. The last time he pried too far into Lucifer's past, Lucifer was out of it for a few weeks. Knowing more about his past was not worth making his favorite person sad.

Lucifer thought for a moment before motioning for Diavolo to ask more questions.

"Is it from the Celestial Realm?"

"Yes, I used to play it on the piano to my brothers and Lilith." Lucifer stared off into a dark corner in the room, lost in memory. Diavolo waited a moment before pulling Lucifer into a tighter embrace. Lucifer looked at his lord before turning in his chair to reciprocate the hug. They sat there for a minute before Lucifer realized why Diavolo came in the first place.

"It's past midnight again isn't it?"

"Most definitely." Diavolo chuckled as he pulled away from the hug. "Much past your bedtime." Lucifer huffed and gave the prince a small glare for the condescending note. But he didn't complain as Diavolo lightly pulled on the brunette's hands.

Lucifer was pulled out of his seat and practically dragged to his room, without even a chance to organize his desk. "Then you'll find something new to work on, then you won't go to sleep, then I won't get cuddles from you," Diavolo said to Lucifer when he wanted to. Lucifer chuckled at Diavolo's childish wish, even if that was his wish as well.

They changed in their sleep clothes and climbed into Lucifer's massive bed. They faced each other for a while, in comfortable silence, just looking. Diavolo broke the silence, "How can you be so beautiful, My Morning Star." He didn't say it like a question, more like a truth. Lucifer cupped Diavolo's face and smiled. No matter how many times the prince called him that, it would never get old.

He scooted over, closer to the red-head, and kissed him. Diavolo put his arms around him to drag him even closer. After a few blissful minutes, Lucifer broke the kiss.

"Thank you, Dia."

"For what?" Diavolo tilted his head, being cutely confused.

Lucifer let out a giggle and sighed, "For everything. Taking care of me. Being with me. Making my brothers happy. Making me happy. I love you Diavolo."

Diavolo blushed as he buried his head in Lucifer's chest. "I love you too, my Morning Star." They fell asleep in each other's arms, as close as possible to each other.
