My Snowflake - Killer Frost/Caitlin Snow x Male meta reader

Training

You were in the speed lab, ready to get going with your training.

"You're here early, monsieur L/N."

"Morning, Sherloque."

"It's Sher-. You pronounced it correctly."

"I did?"

He walks up to you, looking intently at you. And he smiles.

"Ah. Amour. A great feeling in this world, n'est-ce pas? You don't have to tell me. I married the same woman at five different times."

You looked at him. Unbeknown to you, your face was getting a bit red. He just smiled a bit at you.

"Monsieur L/N. Take a word of advice from me. Don't let go. You let go, you will feel sorry. Miss Snow is an amazing woman."

You looked at him puzzled. How did he figure all that out?

"Please, do not insult my intelligence. I am a detective. Besides. It's obvious. I saw you both at Jitters."

You smiled at him. That bastard.

"Sherloque. You are a mad genius."

He tips his hat and walks out.

It's not long until you hear the clicking of her heels.

You look up to not see Caitlin, but Frost looking at you intently.

"Let's get to sparring.", she says coldly.

You look at her in doubt. You watch as she summons two ice blades. This did not seem good.

Timeskip of a good hour

You lay there on the floor. Your face bloodied somewhat of different cuts.

"You know. Frost.", you cough, hacking up some blood on the floor. "If I didn't know any better, I'd say this is a session of slaying, not sparring."

You turn around, only to be met with her shoe on your chest.

"Frost. I don't even know what my powers do, let alone how to use them.", you cough.

"You'll have to. They won't care when they attack you.", she said sternly.

"What?", was all you could ask when you had to roll away from the incoming shards of ice.

"They will not mind ambushing you!", she striked at you again, as you dodged barely.

"They will not mind gutting you in the street!", another strike, barely missing your face.

"They will not mind to-", you summoned a shield, which blocked the next strike, her ice dagger getting stuck in it.

She looked surprised. You used that in order to grab her other wrist and make sure she couldn't attack you.

"Mind to what, Frost?! To slit my throat?! To cut me up into pieces?!", you yelled at her.

"They won't mind to take you away from us!", she yelled.

You went silent. Was that...a tear on her face?

"Frost..."

Her ice daggers disappeared. Another tear appeared in her eye.

"They won't take me away. Not from Caity. Nor from you."

She looked at you in an expression that seemed to be shocked.

"Yes. You said 'us'. Not 'her'.", you replied.

"What difference does that make?", she looked away whilst saying those words.

You held her chin and made her look at you.
