Child!Sollux x Child!Reader - Just rest your head

Slowly, you follow your mother as she drags you along the many aisles. You grumble in protest, but the other shoppers masked your annoyed retorts.
"(Name), dear?" Your mother asks.
"W-what?" You manage to reply, yawning in the process.
She smiles.
"Don't you want to buy anything?"
"No."
You were firm with this decision.
If you bought anything today, you were certain that you wouldn't have enough money to buy the Rabbit plush you had been saving for.
It was very important to you, although you didn't really know why.

Tired, you start to walk down the confectionery aisle, until you bump into something.
"Hey!" An irritated voice calls out.

Or someone.

"S-sorry." You murmur, rubbing your eyes to keep you awake.
"Oh. Hello (Name)!" The voice continues. You see familiar scruffy black hair and two-toned glasses.
"Hi Sollux."
"You look tired." He remarks.
You giggle.
"Yeah."
"Did your parents wake you up early too?"
You nod in response, trying not to fall asleep.

Concern washes over his face, and he takes your hand.
"Let's go sit over there."
"S-sure." You agree.

You watch as more frantic shoppers pass both of you by, and you rest your head on Sollux's shoulder. He squeezes your hand to grab your attention - at least, before you fell asleep.
"Hey, (Name)?" He inquires.

Your eyelids grow heavy as you sink into a deep slumber.

After a few moments, he realises you'd fallen asleep.
Sollux grabs the Rabbit plush he'd bought you from out of his backpack.

"Just rest your head, (Name)."
