Yesterday had not been a good day for Stiles. He'd embarrassed himself in front of the grumpy but beautiful legend that was Derek Hale and he hadn't finished buying the groceries, meaning he'd have to go back again and that meant he could bump into Derek there again and embarrass himself. His life was a mess.

Stiles didn't know if Derek was working today but he definitely didn't make a stop at the tea shop before work to check. In fact he practically ran to the costume shop to avoid being seen by anyone who worked across the street.

Erica was working today too so Monday wasn't going that well for Stiles either.

"So how are things with Derek?" she teased, winking at him.

"Things, there are no things, I don't know what you're talking about, things do not exist, I don't even really know Derek, Derek who?"

Yeah, he was babbling again.

"Um, this is weird that this is happening again, but just to clarify, Derek is that guy walking towards our shop." Erica started cackling like a witch, she was actually wearing a witch's hat. Stiles was wearing devil horns. It was part of the uniform.

"Oh shit," he mumbled thinking about making a run for it but realising it was too late because Derek was already looking at him.

When Derek entered the store Stiles was already blushing, he couldn't take his eyes off the floor. Erica had conveniently disappeared leaving Stiles alone to deal with the customer.

"Hi Stiles."

"Hi Derek."

Derek seemed to actual be smiling today. He could probably sense Stiles' embarrassment and was feeding off his misery. Why did Stiles like him?

"Satomi sent me in here to get some halloween decorations for the shop," informed Derek.

Stiles pointed to the corner and said, "There's some stuff over there."

"Okay, thanks." Derek had a mischievous look on his face. "Nice horns by the way."

Erica was loudly cackling again in the back of the shop. Somehow Stiles face turned an even deeper shade of red that matched the colour of his sparkly, devil horns. He pulled them off his head immediately but Derek had already turned away to browse for decorations.

Derek kept glancing back at Stiles as he shopped but Stiles avoided looking in his direction, pretending to be really busy with the till and random pieces of paper.

"I think I'm gonna get these," informed Derek making his way over to Stiles with arms full of Halloween decorations.

"Okay."

Stiles tried to ring them all up as quickly as he could so Derek could get his beautiful face with its unsettling smile out of his place of work as soon as possible.

"Stiles, did I say something yesterday that made you uncomfortable?" asked Derek looking genuinely concerned that he'd done something wrong.

"No!" exclaimed Stiles rather loudly causing Derek to take a step back out of surprised, "I mean no, of course not, I just… I keep doing and saying stupid things when I'm around you and constantly make an idiot out of myself, I was so embarrassed after yesterday."

"You shouldn't be embarrassed," said Derek, "I don't think you're an idiot. I did at first but that's because you threw toilet paper at me at 1 in the morning, but now I think you're… okay."

"Okay?"

Derek grinned, "Yeah, you're okay."

Erica yelled from the back of the shop, "Guys this isn't the fault in our stars!"

"The what?" asked Derek.

"The fault in our stars," replied Stiles, Derek stared at him blankly, "You haven't seen it? We definitely need to watch that, I mean you need to watch that, not we, don't know why I said we, ignore that."

Derek bit his lip and said, "We should watch it some time. See you tomorrow?"

"Yeah, see you."

Derek left the shop after giving Stiles a little wave. Stiles was confused but happy.

"Stiles hunny you don't work tomorrow, don't you have lacrosse practise?"

"Oh shit."
