A little heated ;)
You walked into the hallway as you usually did delivering transmissions to some of the officials on that floor when you came across pounding and sparks. You kept walking down the hall and glanced into the open doorway but didn't stop. You glanced in to the frame revealing Supreme Leader Ren. You looked at the room that was mainly burning up now and shivered a little to the damage that was done to it knowing that the repair guys would have a busy day. You looked down at your stack of papers and noticed that the bottom packet was meant for him. But he was already standing in front of the doorway looking down at you.
Kylos POV
I am going to kill him. If Hux ever fails me again I will destroy him slowly. Maybe I should call him in here to tempt his spirits.

Someone's coming, Y/N I knew she'd be here I got the timing right. Good.
She might be afraid of me when she sees this I should close the door and bump into her.

I walked through the room until I saw her staring in. She was nervous and confused. But not afraid courageous this one is. If only everyone else was like that.

Damn she looks good in grey, I can't believe she's not with anyone. I want her in my bed with me she looks so ravishing standing there tempting me with her innocent beauty. I want her and I always get what I want.

END POV

He was standing in the doorway merely inches from you as you turned to walk into the room. You stared into his chest and slowly lifted up your head to meet his eyes. He looked at you with lust in his eyes, the kind of fire that said I will never stop until I have you by my side.

"Supreme leader, I have a file," you said as you pulled it from the bottom and handed it to him softly, "for you."

He took it in his hand while still watching your face wanting to take in every part of you each aspect your eyes, lips, hair even your rosy cheeks.

"I don't mean to pry however, are you feeling alright you seem a little... unhinged," you questioned nervously fearing that you should have just turned around and kept walking instead of being curious.
"Yes I'm alright now, if anything makes me 'unhinged' on this ship it's you," he said looking down at your lips.
"Oh I'm terribly sorry I didn't mean to I should go now I'm sorry if I bothered you," you backed away out of the door frame. As he dropped the file on the ground with a loud smack and you flinched looking down at the others you were holding. You stood still not knowing exactly what to do in this situation fearing your life knowing that he could end it within seconds if he wished.
He pulled you into the room by your blouse yanking you into him and sliding the door shut with the lift of his hand. You looked back as it shut quickly. He turned your chin to face him glancing at your lips one final time and finally meeting them with his. For a moment you were shocked but then you gave in. His lips were dark and seductively as they were getting familiar with all of the curves of your own. He brought his other hand resting it on your head entwining his fingers in your hair not wanting the moment to end. But you had to pull away to breath placing your forehead on his chest not wanting to look him the eyes. He rested his chin on top of your head comfortably due to the height difference with his hand still in your hair. He massaged lightly as you stood there against his warm embrace.

"I wanted to tell you that...," he was considering to confess his feelings for you.
"I am,"
"Yes" you smiled up at him innocently.
"Promoting you, to commander of the first order."
You stood silently speechless stepping away from him.
You shook your head no in disbelief
"You don't want it,"
"No it's not that it's just I think Hux is doing a fine job as is and I wouldn't want to imply that he wasn't. He's already under pressure constantly and I wouldn't want to dissatisfy him plus it's way too much responsibility I wouldn't be a good fit I don't know anything about that kind of stuff, I don't even know my way around the ship that well," you spoke quickly creating arguments in your head. He stepped towards you closing the gap again tracing your neck with his thumb. You closed your eyes and leaned into his his hand.
"I have faith in you," he opened his palm so that you could rest your cheek in it. "There is no one else I would even consider for the job." You smiled against his hand as he smirked and added in a few other details he would be personally enjoying with your promotion.
"You will of course be reporting to me much more often than you do now. And well you would be working much more closely with me in general."
You stood there conflicted out of your wits so unsure of yourself.
A worried look came across your face as your smile faded and Kylo took this as his last chance to persuade you, "once you told me to have courage when I had none and so I offer you that same advice you gave me because that small gesture of kindness you offered gave me the strength I needed," he pulled you into him tightly nestling his chin on your head again and wrapping his arms fully around your back.

"Take the job Y/N, I'll keep you away from General Hux as much as I can, however I can't promise not to brag about your accomplishments in every meeting I have with him and you just might be the best commander this order has ever seen," he said sweetly.
You finally nodded to him looking him in the eyes. He knew you were still anxious and terrified but he would keep you in close proximity to him for the preceding years and he knew eventually you would be his General, his second in command.
