The villain's 'epic' introduction

The villain looked like he wanted to protest, but before he could say anything, Willow said in a suggestive tone, "After all, it's already been so late. I don't think a wise and calm villain would delay things any longer for such a petty thing.""Hah, whatever," he sighed dramatically, "I'll make do with whatever for now. Now, listen to my grand introduction, peasant!""You may not know me, Willow Astor, but I know you very well. My name is Liam Sanders, the future CEO of the Sanders Group!"He paused, expecting some sort of reaction. Adelia and Willow just looked at him blankly, not particularly impressed. If this was their original world, they surely would've been shocked, but here, literally everyone was a rich second generation. See that guy walking down the street? Even he has a million dollars to his name. It's not like an unlimited bank balance was anything new here."...And?" Adelia rubbed her ear boredly. "Get to the point, dude.""You! Shut up!" he snapped. The villain seemed to realize this outburst contradicted his 'calm and collected' character and hurriedly fixed his expression. He coughed, "Ahem, as I was saying, I'm the future heir of a large corporation. I had everything. Money, fame, everything. Be it girls or boys, being in my bed was every person's dream—""For what?" Adelia, who easily forgot deceived by his childlike appearance and forgot just how dangerous this little guy was, couldn't help but regain her snarky nature and asked sarcastically, "to read you a bedtime story?""Shut up, you stupid woman! As I thought, all women are stupid! You're the stupidest of them all!" he was about to cry as he muttered, "Y-you...you guys are so...s-so—""Adelia, shut up," Willow glared at Adelia, who was barely stifling her laughter, and turned to the villain. "Hey, look, don't mind my sister. She's just...shitty. Forget her," he tried to appease him and said, "Now, do your introduction, okay? Don't listen to her; you were good before—""GOOD?!" he cried, "I'm bad!""Uh, yeah, bad! You— you were bad before! Keep it up, and say what you want to say, alright?""...Forget it," he got up from his chair and walked to them. "I'll say the main thing now.""Willow and Adelia Astor, I know your secret. I know you aren't from this world. I know...this is the world of a novel."Although Willow knew he had this information, hearing it so clearly still shocked him. Maybe, at the corner of his heart, he was still holding on to the small hope that the secret this person had wasn't that, anything except that. But hearing it so clearly shattered all his sweet fantasies, reminding him of the cold reality.He couldn't speak for a moment, and after a minute, finally said, "...How? How—how do you know?""I was just getting there, if only someone didn't interrupt me," he glared at Adelia. Contrary to before, even Adelia was filled with fear now, no longer daring to provoke him. Forget about provoking; she couldn't even look at the child she so easily pissed off a moment before in the eyes, praying he won't notice her."I-I'm sorry...""Save your apology. I don't want it. Anyway, as I was saying, I had everything a human could ever ask for. Everyone around me treated me with respect and courtesy, always praising me and admiring me. I was always treated like I was the center of the world, the highest authority, and the one people paid most attention to wherever I went. If the world is a story, I always thought that I must be the main character, someone everyone looks up to and follows."Jealousy flashed in his eyes as he spat out, "Imagine how it must've been to suddenly know that I, was, in fact, not the main character. I wasn't even a side, you know? Just an extra," he took an ornamental pot and threw it on the floor, "JUST A DAMN EXTRA! Someone who didn't even have a name or mention in the main story!"
