Gavin tilted his head slightly, his expression one of mild curiosity. He seemed genuinely interested in watching Liza continue praising herself without so much as a flinch. Meanwhile, Serena’s face was a picture of discomfort. Every word Liza spoke felt like a dagger aimed directly at her. She took a small step back, her body trembling visibly. Her voice quivered as she stammered, “I... I’m not Liza. I’m Serena.” Her mind raced with indignation. How could Mrs. Stone possibly think that Liza was more beautiful than her? Was this woman blind? The praise for Liza felt like a slap to her face. The room descended into a heavy silence once more. Unable to bear the tension, Brandon stepped forward in an attempt to salvage the situation. “Master, Madam, my fiancée has always been Serena. I have no involvement with Liza.” Liza turned toward Gavin, feigning dissatisfaction. Her delicate hand lightly smacked his shoulder as she pouted. “Look at you! You’ve embarrassed me by mixing up someone else’s fiancée's name. It’s so frustrating. You’re unbelievable!” Her words were sugary sweet, but inwardly, she cringed at her own performance. She couldn’t believe she was playing along with this charade just to expose Serena. Gavin reached for her hand, clasping it firmly yet gently. His deep, steady voice carried an air of absolute authority. “The Stone Family’s intelligence network has never made a mistake. According to our information, Brandon’s fiancée is indeed Liza, and Serena is her younger sister. As for what transpired between them, it’s not something significant enough for our network to investigate.” He didn’t explicitly say much, yet his words managed to lay bare the entire situation. “Huh?” Liza gasped, her expression deliberately exaggerated. “So Liza is supposed to be Brandon’s fiancée? Then how did it end up being Serena? And Serena, didn’t you claim that your sister stole your man? But it seems like you’re the one who actually stole your sister’s man. Isn’t that right?” The implication hung in the air, undeniable and sharp. The idea of a younger sister taking her older sister’s fiancé didn’t sit well with anyone, no matter how it was framed. Brandon’s fists clenched tightly, his composure unraveling. The weight of the situation was unbearable, and he struggled to form a coherent response. “Master, I…” Liza didn’t let him finish. Her voice carried a note of mockery as she continued, “Honestly, if someone wants to steal another person’s fiancé, that’s their own issue. It reflects poorly on their character. But what’s truly appalling is doing such a thing and then turning around to play the victim. To blame your sister for stealing your fiancé and even calling her a shameless mistress—don’t you think that’s going too far?” Her words were sharp and direct, cutting through any remaining pretense. Serena’s face turned an ashen shade, her lips trembling as she realized there was no escape from the harsh reality laid out before her.Liza sighed, her tone carrying a trace of disappointment as she addressed Serena and Brandon. "What can I say? I truly feel sorry for Liza. Imagine losing your fiancé to your own younger sister and then being accused of something you never did. It's bad enough to suffer such a betrayal, but having your reputation dragged through the mud on top of that? It's heartbreaking. That poor woman." Brandon froze in place, her words striking a nerve. He couldn’t help but wonder if Liza had truly felt this way after losing him. Serena, on the other hand, turned pale. Her breath hitched as Liza’s remarks hit her like a slap. All her careful scheming, all her efforts to rid herself of the third-party label, had unraveled within moments of stepping foot into Longwan Residential. The tables had turned, and the blame for being a mistress had landed squarely back on her shoulders. She clenched her fists in frustration. This isn’t fair! The mistress was supposed to be Liza, not her! In her mind, the label belonged to the one who wasn’t loved, the outsider who didn’t belong in the relationship. I was the one Brandon truly cared about, so how could I be called the third party? The butler, who had been observing the drama unfold, shook his head in disappointment. His voice carried a stern edge as he remarked, “So, you’re the third party after all. To think I actually felt sympathy for you earlier when you accused your sister. But let’s clarify a few things. You mentioned Liza came back from the countryside, right? If I recall correctly, Liza is the legitimate eldest daughter of the Sinclair family. And you… aren’t you the illegitimate daughter from when Mr. Sinclair had an affair? For an illegitimate daughter to slander the rightful heir of the Sinclair family—it’s truly shameless.” The murmurs of agreement from the nearby servants added fuel to the fire. “She’s utterly shameless,” one said. “Like mother, like daughter,” another chimed in. “Her mother was a mistress, and now she’s walking the same path. It’s no wonder she’s meddling in other people’s relationships.” Hearing these biting comments, Serena’s face flushed with humiliation. Rage boiled within her, but she maintained her composed, innocent facade. She had come to Longwan Residential to elevate her status, not to be scorned by mere servants. What gives these lowly people the right to insult me? And then there was Mrs. Stone. Her elegant demeanor infuriated Serena even more. She looks like nothing but a vixen who seduced Gavin. It’s only a matter of time before he tires of her and throws her out. Despite her seething anger, Serena forced herself to speak softly, keeping her voice light and pitiful. “Mrs. Stone, may I know what I’ve done to offend you? Why are you treating me this way?” Liza tilted her head playfully, raising her hand to wag a finger. “Offend me? Oh no, you’ve never done anything to me personally.” Her voice turned light and airy, almost teasing. “It’s just that I have a deep disdain for third parties and illegitimate children. They go against everything I stand for, you see. And unfortunately, you embody both of those things.” She let out a theatrical sigh, as if genuinely troubled by the situation. “Perhaps it’s my fault for being spoiled by Brother Gavin. He has this habit of encouraging me to speak my mind, you know? He always says I’m so honest and adorable when I tell the truth. So, naturally, you won’t hold this against me, right? I mean, I wasn’t intentionally trying to target you. It’s just my nature to speak plainly.” Her words were laced with subtle mockery, leaving Serena simmering in silent rage, unable to respond.
