Four cousins of Korean-Thai descent made of two sets of sisters, Serena and Melanie, and Kierra and Linna, with their fathers being best friends and marrying into the same family with the four's mothers being sisters. The four were currently living and studying abroad in Seoul, South Korea for the past several years while both of their families lived in the US, specifically in Southern California. Thee quaret along with their family visited both Thailand and South Korea over the years when they were younger during holidays and vacations, but wanted to study abroad due to their older cousins, Lina and Dana, who were also a pair of sisters. The four settled in South Korea at their suggestions. The quartet went by their Korean names, Jinae, Chaewon, Hayoun, and Yiseul, respectively, for convenience. The cousins were currently on winter break from the university and at the moment they were working at a restaurant, Gong's Food, instead of having fun like a majority of their peers.

"Sir, there is no need for your anger."

Linna had shielded herself in time by using one of the serving trays to block the shattering glass shards due to the table she was currently tending to had thrown at their glass angrily at her. The customer began yelling at her incoherently. She remained calm and spoke after the customer quieted down.

"I'm only here to inform your table that no alcohol will be further served as y'all reached the allowed limits within the set hour."

"That is total bull! We only had six bottles. There's a lot of us. How could we reach the limits?"

"Sir, there's only three in your party and yo-

Before Linna could even finish her explanation, the owner, Gong Hyungjin, immediately came over to disfused the situation.

"We're so sorry, sir. I'll have her bring out another one on the house."

He glared at Linna.

"Jung Yiseul, apologize."

Linna gave him a weird look.

"I'm not apologizing to him, Mr. Gong."

"I'm ordering you to do so, Jung Yiseul."

"No."

"Jung Yiseul, apologize to this gentleman right now."

"No. He's not a gentleman and I'm no-ahh!"

Hyungjin roughly placed his hand on her neck and forced her to bow to the customers. When Serena witnessed the incident, she instantly ran over to aid her younger cousin as the other two were busy in other areas of the restaurant. She kicked the back of the owner's thighs to knock him down to his knees as he released Linna's neck to break his fall with his own hands. Serena swiftly pulled Linna away from the older man and the table with a glare directed at them all.

"How dare you lay a hand on her? There's clearly a notice on the wall of how much alcohol is served to a table per party and per hour."

"Park Jinae! How dare you disrespect me?" The owner shouted at her.

Hyungjin could barely stand up due to landing on a few of the smaller shards of the shattered glass.

"Let's go."

Serena swiftly pulled Linna along with her to the back of the store. Kierra and Melanie asked what had happened as they heard loud sounds and spotted the other two while following the pair.

"Mr. Gong is being an like always." Serena replied before casting them an apologetic look.

"I don't know about y'all, but I'm quitting despite not putting in my one month's notice. I guess we'll be working with Jisung and Heeyeol for the winter holiday after all."

The others nodded, thinking the same. Jisung was Dana's Korean name while Heeyeol was Lina's Korean name and both ran a cafe called 'Simplistic'. Since the quartet decided to move abroad for their studies, the pair has been taking care of them since and helps when needed or whenever their parents worried a little too much about the four. Anyway, Serena quickly changed back into her regular clothes, left her uniform, and grabbed her belongings. The other three did the same and the four returned to the front.

"I will not pay any of you if leave." Hyungjin threatened.

"The four of you clean up this mess right now and take care of the customers."

"I quit." The cousins chimed at the same time with a smirk.

"Have fun finding a replacement for us on such short notice." Linna added with a knowing look.

"Don't go. I need you this weekend. It's Christmas Day! I don't have any one else to do it!" Hyungjin yelled after them before changing gears.

"Yah! I'll make sure you won't get work anywhere else!"

"We'll take our chances!" Melanie replied nonchalantly.

"We're not taking any more crap from you either, Mr. Gong." Kierra said with a firm tone and gave him a firmer look.

"So, you don't scare us."

The customers were staring and whispering, wondering what was going on, unlike the employees, minding their own business.

"Have a good day, sir."

The quartet mocked salute as they turned away and left.

"Despite how small the place is, it's pretty cute." Melanie complimented upon the place when the quartet arrived at the location of their cousins' cafe.

The place wasn't that far from their school and their home compared to Gong's Food. After notifying Dana and Lina of their current unemployed statuses, she wanted the quartet to come by for preparation before the grand opening.

"Seems like a typical cafe though." Linna said with a smile.

"I like it."

"We're glad." A male voice said from behind them.

The quartet turned to see two familiar faces and their new co-workers, Moon Chanran and Lee Eunchan. Eunchan was the one that had spoken.

"Wasn't Heeyeol and Jisung supposed to meet us here?" Serena inquired as Chanran responded.

"They're taking care of other things and asked us to step in."

"But since it's you four, we know that y'all will catch on fairly quickly." Eunchan commented with a goofy smile.

"I dunno about that." Kierra said with a playful tone as Eunchan nudged her with her doing the same back.

"No, I agree." Chanran concurred with a smile as he gave the quartet a serious look.

"Just in time, too, since the two had to let go a few of the staff they hired previously due to misconduct."

"Oh, wow, really? What they do?" Linna asked.

"One was for ual harrassment. Another was for stealing products. The third for vandalism. As for the fourth, fifth, and sixth ones, Well, they just completely stopped coming in despite being called and not answering." Eunchan listed with explanation.

"Wow."

"Yeah."

Now the four understood why their older cousins had asked for them to work for them, still leaving the choice up to them at the time.

"Anyway, welcome to Simplistic." Chanran greeted as he passed by to unlock the doors while casting them with a playful smile, "Now, let's head inside to prep y'all for this Thursday's soft opening."

The duo explained to the quartet on how Simplistic ran as well as where things were designated and for usage. The quartet had visited several times and knew the menu by heart, but other than that, that was about it. Same with the workers, as they only ever came in the two males or their older cousins were working. The group spent all evening going over the menu, prices, set-up, uniforms, other work-related functions, and non-work issues. The cafe operated for seven days a week with their set hours. From Monday through Thursday, the hours were from three in the afternoon to nine at night. Then from Friday through Sunday, the hours were ten in the morning to six in the evening. The four also learned that besides them, their older cousins, and the male pair, there were two other workers they haven't met yet.

"So there's an order of seaweed rice ball, a loaded mochi waffle, a lemon cloud ade, and a cherry blossom ice cream." Melanie read back the order before annoucing the overall total.

"That'll be a total of thirteen thousand and five hundred won."

Melanie ran the register alone while Kierra, Linna, and Serena made the orders as Eunchan and Chanran ran out the orders and cleaned the area. Dana and Lina had come in earlier to prep and open the cafe while the other co-workers, Lee Hanyoung and Hwang Junyoung were off today. Anyhow, all worked every positions and assisted the other if needed as the orders were all made to order. As for their uniforms, it consisted of an ash gray visor with the shop's logo, a beige sweater also with the shop's logo, black leggings or pants, black sneakers, and an ash gray striped apron with the shop's logo, too. Simplistic sold a variety of items from bottled waters, canned milkis, fruit slushies, fruit slushies with cotton candy, ice cream, ice bars, rice balls, corn cheese, tteokbokki, bagels, and mochi waffles. And if you came in during the last half an hour before closing, all items were half off, so the shop could start afresh the next day.

"Here's two sets of furikake rice balls."

Kierra placed the two small plates onto a tray.

"Awesome. Thanks."

Chanran took the tray, placing it alongside an original and apple milkis before he ran out the order to the customer.

"Hayoun, do you have the spicy tuna roll ready for customer number twenty-four?"

Serena looked over at her cousin while setting a mango slushie onto another tray.

"Yeah. Here you go."

Kierra handed her the plate as Serena thanked her while setting the item alongside the slushie and a bottle of water.

"Yieul, do you have that moffle bomb and a plain one ready?"

"Just finished it. There you go."

Linna placed it onto another tray alongside a plain mochi waffle.

"Nice."

"Thanks." Eunchan flashed them a smile before taking the order upon returning from delivering another order.

"Y'all are doing a great job."

"Thank you and you, too." Serena responded while placing a plate of plain mochi waffles onto another tray.

"This one is ready with the two mango cloud ades and corn cheese for customer number six, too."

"Nice."

Eunchan also took that order with Chanran coming up to the counter, awaiting for the next set of order to go out.

"Hey, Chanran." Melanie called out to him after she got done with a customer.

"What's up?"

"That one table on the far left corner bought more drinks just now. They're the one that had that large order of tteokbokki." She began explaining as she rushed to grab several cans and bottl
