“AH! KUYA OPPA is a killjoy,” Eun Young complained as they walked on their way home. "We still want to party."
“Ani. No party for you two. You have school tomorrow and Cheska and I have an early tour. You went shopping already, what are you still complaining about?” 
They just had their meal from the restaurant and they were walking home to burn down the food they ate.
It was a good chatter. Carter and Eun Young quarreled loudly but Cheska could still see the love between the siblings. It was another side of Carter that was endearing. He was even making a joke with her. Eun Young said it means that Carter felt comfortable with her.
"Unnie, you want to do karaoke, right?" Eun Young asked and hugged her arm.
She stroked the teenager’s hair. “Some other time. I am staying for a week here in Seoul, I am not going anywhere. We still have a lot of time together.”
"I thought you were on my side, unnie," Eun Young said in a whiny voice.
"I am," Cheska answered, consoling the girl a little.
“But you forgot that Cheska is a hard-working student. It is school before anything else.” And Carter winked at Cheska.
Eun Young rolled her eyeballs. “Two model students. Daebak!” the teen said sarcastically and clapped her hands. "I will ever win."
“You can do whatever you want once you are graduated,” Cheska said.
"When you're fifty years old, I'll let you have a boyfriend and watch a sexy dance," Carter said and folded his arms.
"Kuya Oppa!" Eun Young's complained in exaggeration.
Carter gave his sister five thousand won. "Go and buy a yogurt drink."
"Is this all for me?" Eun Young's eyes were twinkling. 
"Buy one for umma and Cheska as well." 
Eun Young quickly went to the G25 Convenience Store a few meters in ahead of them.
“Thank you for going with her to go shopping.” He raised up the shopping bags he had been carrying for them. “I think you bought more than you were intending to buy.”
“She can be persuasive. But, I needed those anyway since I only brought a few clothes with me.”
"How much was my share for our dinner?” he asked.
“Oh, don’t worry about it. It was my treat for Eun Young…”
"And I just showed up uninvited to your dinner,” he added. “It’s only right to have my share of the bill. Fair is fair.”
He really had so much pride that he would not take her treating him to dinner. "Just cook something for me and we’ll be even."
“I will really cook for you while you’re staying with us. How about a sexy dance? ”
He swayed his body in seductive moves while slowly lowering the zipper of his jacket. Cheska's chest heaved rapidly. He was stripteasing in the middle of the street for her! And he looked captivating with his eyes on her. 
She immediately put her hands over her eyes. Not here. I’m not prepared. "I'm still young. I’m not yet allowed with those kinds of things.”
"And when will you be allowed for a sexy dance?" he asked.
"When I'm fifty," she said.
Cheska put down her hands when she heard Carter laugh. He was zipping up his jacket now. "Then you will have a boring life for a long, long time."
"You’re the one who said that Eun Young was allowed for a sexy dance when she’s fifty."
“It’s because she’s my sister. I probably won’t even allow a man to approach her even if she turned a hundred years old.”
"And I’m not your sister so is that mean I can go to a gay bar?”
“I’m here volunteering myself already and you’re still thinking of going to a gay bar? You’re kinda insulting me, you know that?”
She was not used to this. She never lusted over Doc Darryl when they were still talking before. Attraction and lusting over were two different things. Admiring a good-looking man and imagining him doing a striptease were also two different things. Her love for Doc Darryl was pure and unadulterated.
And that's how she wanted to feel about Carter. But how could she ever feel innocent and pure love for Carter when they were just shamelessly flirting with her like this? She couldn’t even handle the introduction of his striptease. Her knees were already shaking.
“If you’re doing it, don’t do that thing in the middle of the road. We might go to jail for that.”
“Well, we can’t do it at home either. Umma will beat me. Don't think that I'm only offering sexy dance to anyone. You are special. And I want your vacation here in Seoul to be a special one as well.”
“It’s fine without the sexy dance. Just please don’t offer it to anyone else either. They might get traumatized.” She should be the only one who would ever see that sexy dance in the future. Maybe she would be prepared tomorrow.
“Did you give your sexy dance performance to unnie out here? Ew! You’re so cringey, Kuya Oppa,” Eun Young said, dragging her brother away.
"I thought you were proud of my handsomeness."
“That was a joke. Da mee aeyo,” the teen grinned.
The two were having a sibling banter when someone called Carter. 
“Carter Oppa! Oppa!” a woman with an angelic face called him.
