A book and your head on my lap [sentrywire | Cypher/Killjoy]
(This takes the inspiration from the fourth picture attached in this post. Cypher is the red figure and Killjoy is the blue figure.)
Sometimes, they shared room together after officially announced that they were a thing. Killjoy usually came to Cypher's bedroom since he had the biggest bedroom in the headquarters. As night owls, both of them slept later compare to the other agents.
That day, Killjoy came to his room because she couldn't sleep well even though she needed it. Brimstone would be angry if he knew Killjoy didn't sleep since she had a mission on the next day.
He heard knocks on the door and her voice calling his name, "Um, Cypher?"
Opening the door, Cypher spotted the girl in her yellow pajamas. He didn't need to ask why she came because he already knew.
"Come in."
He just let her in and returned to his current activity, reading a book he got from Sova as a birthday gift. She lay her head down on his lap. One of his hands caressed her thick raven hair, while the other held the book. Not long after, she slowly drifted down to the dreamland as Cypher tugged the blanket and smiled softly.
"Good night, my Little Engineer."
