What's going on between these two?

Madison POV

I stepped out of the kitchen with a tray of pasta in my hand. I walked to the dining table and gently kept down the tray in my hand.

“Madison I think I am beginning to crave ice cream” Krystal pouts her lips at me. I laughed lowly and raised a brow at her.

“See this 22 years old doctor craving ice cream” I scoffed and she clicks her tongue at me.

“Am I not human Madison? I can..” her statements were interrupted by the sound of the door bell. My eyes went wide immediately, I clearly know who is at my door “Kingsley??” Krystal exclaimed as if she doesn’t know we are both expecting him.

“Yes!!!” I squealed childishly and ran to the door to welcome him in

“Damn, you said nothing yet about my ice cream” she groaned behind me but I ignored her and went to get the door.
