I grew up abroad. My mother feared I might marry a foreign man, so she arranged an engagement for me with a talented and handsome man in Flodon. She insisted that I return home to get engaged. I came back and started shopping for an engagement dress at a luxury boutique. I selected an off-white strapless gown and decided to try it on. Suddenly, a woman nearby glanced at the dress in my hand and told the saleswoman, “That’s a unique design. Let me try it.” The saleswoman immediately yanked it out of my hands. I protested indignantly, “Excuse me, I was here first. Don’t you understand the principle of ‘first come, first served’? Or do you just not care about common decency?” The woman scoffed and retorted, “This dress costs $188,000. Do you really think a broke nobody like you can even afford it? “I’m Lucas Goodwin’s sister in all but blood. He’s the chairman of Goodwin’s Group. In Flodon, the Goodwin family sets the rules.” What a coincidence! Lucas Goodwin was my fiance! I immediately called him and said, “Hey, your ‘sister in all but blood’ just stole my engagement dress. Do something about it.”
