The sprawling shopping mall stretched out before Moonji, its grandeur and opulence a sight to behold. She couldn't help but marvel at the sheer size of it all, her childlike enthusiasm bubbling over. "Omooo~~ So this is a shopping mall? It's... it's... big!! Ooo Maa Gaa," she exclaimed, hopping in delight, her voice laced with an attempt at emulating the mannerisms of the wealthy. Her swift steps struggled to keep pace with Kai's determined stride as she tried to match his demeanour.

Born into a very inferior background, Moonji had spent years perfecting the art of pretence. In front of her school friends, she had always feigned affluence, hiding her modest origins behind a carefully crafted facade of wealth and extravagance. Yet, as she ventured deeper into the world of Kai, her charade was unravelling faster than she could comprehend.

Yearning to establish a closer connection, Moonji extended her hand, hoping for the subtle intimacy that couples often shared. However, her bold attempt was swiftly rebuffed as Kai pushed her away roughly, his words laced with a sharp warning, "Don't you dare to touch me! Not even a single strand of my hair." He spoke in English once more, and although Moonji didn't fully comprehend the language, she could discern his intent from the stern body language. "Remember, this is just a play in front of my friends. We don't have to have a real connection," He added as he walked pass by her, slightly bump into her shoulder. 

Moonji, her wig slightly askew from Kai's push, hastily adjusted it, casting a quick glance at him. Kai's stern voice carried back to her as he ventured further ahead, "Could you walk like a human?" It was a reprimand that left Moonji feeling flustered and unsure.

"What? I can't understand you if you talk that fast in English," she protested with an innocent charm, her eyes adorned with a playful wink.

Born and raised in a world far removed from the affluence she was now exposed to, Moonji had honed her skills in blending in with the elite, adopting the superficial mannerisms and expressions of wealth. Her proficiency in mimicking the speech and demeanour of the privileged class was her armour, a shield against her own humble beginnings.

"Aurrgghhhh, what's wrong with you? showing those scary eyes to me?" Kai grimaced and hugged himself, an expression of sheer discomfort. Moonji couldn't believe her ears as she heard Kai speaking in Korean, a language so familiar to her. It was a revelation that left her momentarily stunned.

"Come on, if you plan to talk all day long, let's just cancel this shopping trip," Kai proposed, switching back to English. Moonji nodded in reluctant agreement, having realized that while Kai understood Korean, he struggled to communicate fluently in their language.

The moment she stepped into the boutique, her jaw nearly dropped as she caught sight of the exorbitant price tags adorning the luxurious items. "Kai, I think we entered the wrong boutique. It's really expensive here," she whispered in a hushed tone, hoping for his validation.

Kai's response, delivered with an air of arrogance, alleviated her concerns. "Don't worry. This shopping complex is mine. You could take anything you want. Everything is on me." His words reassured her, albeit with a hint of condescension.

Born into a life where financial constraints had been a daily reality, Moonji had grown accustomed to budgeting and frugality. The concept of extravagance was foreign to her, and the staggering price tags of the items around her were a stark reminder of the world she had longed to enter.

"Are you sure?" she sought confirmation, still awed by the extravagant surroundings. As she watched Kai stride confidently toward the boutique staff, Moonji stood awkwardly at a distance. She hesitated even to sit on the luxurious bench, fearing it might be too costly to use.

"Kai! Kai?" she called out as she saw him walking out of the boutique, leaving her alone. A staff member approached her, addressing her as "Miss Ra" and ushering her toward the dressing rooms, explaining that Kai had requested they dress her up and select clothes on his behalf. Moonji complied, following the staff member as she navigated her way through the boutique.

Hours passed as Moonji tried on various outfits, her astonishment growing with each expensive garment she donned. After the lengthy process, a staff member approached her with a lengthy list of clothing items. "Miss Ra, Master Kim asked me to pick 20 dresses, 20 sets of pyjamas, 20 sets of underwear, 20 shirts, 10 jackets, 20 pairs of pants, and 5 sets of bikinis." The sheer quantity left Moonji momentarily dumbfounded.

"Wait? Why do I need bikinis?" Moonji inquired, but all she received in response was a nonchalant shrug. She asked, "How am I supposed to carry all these items?"

The staff member assured her, "The delivery crew will send it to Master Kim's house. Thank you. You can wait here because Master Kim is on his way." Moonji nodded, relieved by the prospect of not having to carry the extensive wardrobe herself.

Born and raised in a world where budgeting and thriftiness were a way of life, Moonji had never encountered such a lavish shopping spree. The bewildering array of clothes, the extravagant price tags, and the notion of owning so much left her feeling overwhelmed.

Soon, Kai approached her, and Moonji seized the opportunity to question his absence. "Where have you been?" she inquired, her curiosity piqued.

"You don't need to know. Let's go," he replied curtly, leading her toward another store. They arrived at a shop specializing in a couple of love items. Kai handed her his black card with a simple directive, "Go and buy some lover stuff, something that will convince people about our fake relationship." Moonji nodded, accepting the card with an understanding nod.

Born in a world where even minor expenses required careful consideration, Moonji approached the cash register with a mix of excitement and apprehension. She had never held such a powerful financial tool in her hands before, and the prospect of using it felt both thrilling and daunting.

As she entered the store, she briefly stepped back out and approached Kai again, her brow furrowed with uncertainty. "How am I going to pay using a card?" she asked, a hint of confusion in her voice. Kai regarded her with a look of disbelief. "Just give the cashier the card and then take it back," he explained, his tone reflecting the simplicity of the process.

Moonji returned to the store, understanding how to use the card, and after a few minutes, she emerged with three sizable shopping bags b with lover items. Kai, upon seeing her haul, appeared taken aback. "Why are there so many couple things?" he queried.

"As you said, things that will convince people about us," she replied with an impish smile, satisfied with her choices.

The day of shopping concluded with Kai and Moonji making their way to his lavish penthouse. It was located within the most expensive condominium in Korea, a building that spoke of luxury in every facet. Moonji's eyes widened in sheer disbelief as she stepped into the stunning penthouse, the opulence of it all taking her breath away. She couldn't help but notice the grandeur of the surroundings, from the expansive living area to the presence of a large jacuzzi, which now explained the need for bikinis. The enormity of the experience left Moonji in awe.

Moonji gingerly placed the shopping bags on the coffee table, her gaze sweeping across the lavish living space. She began unpacking the couple of items she had purchased earlier, arranging them thoughtfully. Then, a thought struck her, and she turned to Kai. "Why do we need a couple of plush?" she asked, pointing to two cute stuffed animals she had bought.

"Well, when your friends come, they will see these plush toys on your bed and one on mine, too. That way, they'll definitely think we're a couple," she explained with a charming, childlike voice, masking the turmoil within her as she grappled with the extravagant lifestyle that had become her reality.

"Okay, then. We need a couple of phone straps, a couple of pillows, a couple of phone covers, a couple of caps, a couple of mugs, a couple of plates, a couple of wristbands, rings, keychains, and a couple of shirts. Those are the essentials," she continued, her excitement palpable.

As she continued to arrange a couple of items, Moonji was acutely aware of the stark contrast between her former life and her new one. The extravagant world she now inhabited was beyond her wildest dreams, and the internal battle to reconcile her past with her present raged on. "Kai! We also need a couple of photos," Moonji exclaimed as she saw Kai heading toward his room. "Sure, your room is the one in front of mine. All your stuff has already been arranged in there," Kai informed her, leaving her with a matter-of-fact tone. Moonji rushed to gather the lovers' merchandise and presented them to Kai, hoping to sway him. "Wait, take these cute couple of things and arrange them in your room."

"Never," Kai replied sternly, shutting his bedroom door firmly and leaving Moonji standing there, her plans thwarted and her heart heavy with the weight of the secrets she carried.
