Lydia is walking down the aisle of the vegetables part of the supermarket when she hears an all too familiar voice rambling about the whole male circumcision. She rolls her eyes fondly, that would none other than Stiles. She's about to call out to him when she sees who it is standing next to her friend. Derek Hale. It's only been three days since Stiles and Derek talk to each other in Red Riding Hood, the heavenly small shop, only the two of them (he told Lydia about it), and she honestly thinks they hit it off immediately.

Only been three days, and of course they're groceries shopping together, of course, why hasn't she thought of bringing Aiden with her before?

She's one of the most thrilled people among their friends, aside from Scott, when Stiles told them about his crush on the Sourwolf—how Stiles called the man before he puts a name to a face—a year ago. She still remembers exactly that he said, "He's so grumpy I want to put a smile to that ridiculously attractive face."

She's a good judge of a character. Not to show off, she sometimes just knows who has a good intention towards them and who has a bad one. That guy Danny befriended with two years ago, for example. He was almost ruining Danny and Ethan's relationship, almost. Too bad she discovers the lies he shoves Danny with, and too bad Danny loves Ethan too much to care.

Alright, Stiles is starting to rub off on her. Since when has she developed a habit to ramble off even in her thoughts?

Anyway, back to the point, when she first saw Derek, she just knew he was the perfect one for Stiles, with all his goods and his flaws. Not-so-rarely she catch Derek took a glance towards Stiles just as much as Stiles did Derek. She kept quiet about it, if only to see how long it would take for them to get their heads out of their asses and just make a move.

She should thank Laura, in all honesty, because if that stunning woman hadn't dragged Derek down to their table in that fateful day, Lydia swears she would have done Stiles. They both created the UST without each other's knowledge, and it was starting to drive her nuts.

Of course, even though she's a good judge of a character, she wouldn't have known Derek is such a cliché if she hasn't seen it for herself when she watches them pay, or, more like, Derek pays.

"Damn it, Derek, I said I would pay."

"You did yesterday for the coffees and lunches. These junk of foods would end up in my apartment, anyway."

"But I would definitely be the one who swipe them empty. I have a stomach's capacity of a dragon." Though as Stiles says this, Derek gives the cashier his card, and Stiles does nothing to prevent it from happening. Lydia chuckled. How cute.

"I know."

"Hey! You're not supposed to agree to that!" Stiles let out an indignant noise. Derek laughs. "Wait, you—don't try to change the subject."

"I don't. You do."

"Fine. But this thing isn't done and I'm paying next time."

"Whatever makes you sleep at night, sweetie."

"Swee—Derek, tell me you didn't just call me that. Grumpy, Broody, Gloomy Derek Hale didn't just call me a swee—wait, no, you know what? I don't want to finish that word."

Derek laughed, "But I just did, Stiles."

Lydia trails them with her eyes in delight. Derek walks first to the door—still exchanging snarky words with Stiles—and holds it open until Stiles is already outside, then opens his car's trunk, putting the plastic bags in it and close the trunk's door. He then proceeds to walk to the passenger's side, opens the door for Stiles before jogging around the front of the car to the driver's seat.

Who knows a fucking cliché with a face of broody and stubbly and mass murderer-y—Stiles' words, not hers—Derek Hale truly exists? She is conflicted between cooing and stifling a laugh. It's a hard effort, really, it's a fucking hilarious sight to witness, but utterly cute for words at the same time.

But then, another part of her is just really, really glad Stiles found Derek.
