I'm Not A Substitute, I'm His Aunt

I came home from abroad to save my nephew's company from going bust, and also to attend his wedding with his sweetheart. But just as the banquet was about to start, a barrage of comments suddenly popped up before my eyes: [Thank goodness the sweetheart is clever and came up with the idea of framing the substitute for poisoning! The male lead will definitely be over with the substitute after this!] [Exactly! So what if the substitute has stayed by his side for ten years? The male lead still loves his sweetheart the most!] Elaine Geston, decked out in a luxury wedding gown, strutted up to me with her nose in the air, looking smug. "So you're the woman Nolan has cherished for ten years? I hate to break it to you, but you're just a substitute for me! You should get lost if you know what's good for you!" I glanced down at my phone, checking the stock prices, not in the mood to deal with her. She suddenly looked shocked. She picked up one of the two glasses of wine prepared for the newlyweds, sniffed it, then pointed a finger at me and yelled, "What a vile woman! You actually poisoned the wine! Just because Nolan loves me, you want to kill us both!" Hearing this, the security guards instantly surrounded me, looking hostile. I was totally baffled. I pointed at my nephew, who was chatting with guests outside the venue, and said, "What substitute? Ask your husband if he dares to treat his own aunt as a substitute. Does he want his whole family to beat him up? Does he want his company to go bankrupt?" The comments went wild. [Oh crap, she's not a substitute but his aunt? The sweetheart's messed up big time!]
