It's completely casual, him and her.
Wanting his arms around her on a bad day? The constant desire to be near him? The way hearing his name quickens her pulse?
Totally casual, she reminds herself.
The fact that she wants to stab a fork into her thigh when George mentions setting Derek up? The constant ache in her chest? That's normal. Absolutely casual. She can be casual about it.
"Maybe," Derek whispers in the dark, fingers trailing her hips, "we should move in together."
"Okay," she says.
Their tones are each casual, but this Thing between them? It's anything but.
