Dark Temptation Gellert Grindelwald x female reader

Protective

No matter how long or how hard you thought about it, you had no clue to who your secret admirer was. The obvious was that it was someone inside Nurmengard. It could be one of hundreds of guys, there is only two you were certain it is not. One being your own boyfriend and the other being Credence, because he is like a little brother to you. You were also fairly sure it wasn't Abernathy either,he didn't seem the type,but you never know. Then a new though entered your mind,if you hadn't been with Grindelwald last night they could have done any thing to you that thought scared you.

You are staring out the window so intently watching the falling snow,that you didn't hear someone enter the room. You weren't aware you had company,until you felt strong arms wrap around your waist from behind, causing you to jump
"It's alright love,it's only me" came the soothing voice of your handsome leader/boyfriend. You turned in his arms to face him,and pull him into a hug.
"What's wrong y/n?" He asks concerned,you look up to his beautiful eyes and say
"Just a bad thought, that's all"

"About what?" He asks
"Well, since I was with you last night,my so called admirer got into my room...I was just thinking...what if I was in my room last night? What could they have done to me?"
"If that had happened,I'd have killed them for laying a finger on you,for you are mine and no one else's" Gellert tells you,anger clear in his mismatched eyes
"You know most people don't like a posseive other half,but I like it" you tell him.

He kisses your forehead and says
"I'll make sure no one harms you. And if they try,then they shall suffer unbearable pain"
"But how? No one but Queenie and Credence know that we are together?" You ask him confused
"Simple,we shall have a party and let everyone figure it out"
"You mean I have to wear a dress?" You tell him horrified,he just simply smirks at you.
