Reborn As An Extra : I'm gonna mess up everything

Esdeath burst into uncontrollable laughter, rolling around on her bed in her dorm room. "Bwahahaha... Hahaha!" She laughed so hard that tears formed at the corners of her eyes. Finally, after what felt like an eternity, she calmed down, sitting up and taking a deep breath. "I bet Ethan's face was priceless..." she chuckled, imagining the shock on his face.

She knew the importance of the system she had. Unlike others,  system could instantly refine essence stones—except for the highest-ranking ones. In the main storyline, Ethan was supposed to discover this ability later that night, making him the first to refine the Moonblade Essence Stone. But Esdeath had swooped in and stolen his thunder.

"I don't need everyone's attention, but I couldn't pass up twenty silver coins," Esdeath mused, pulling out a small pouch filled with coins and feeling their weight in her palm. "My idiot father didn't give me any pocket money, and I'm broke. But for my future plans, money is something I absolutely need."

She frowned, calculating her finances. "Hmm... Twenty silver coins isn't enough. I need more, especially since I'll soon be going on a small trip. The travel costs will eat up most of this."

But as she thought about the SP (Self-worth Points) she might have earned from winning, a sly grin crept onto her face. "Let's see how many SP points I got. I bet I'll get a lot more when everyone hears I won the competition."

With that thought, she willed her status screen to appear.

Suddenly, a notification popped up:

<Alert: You broke the main storyline. Ethan should have been the one to win the competition.>

<No SP points will be distributed.>

Esdeath stared at the floating text, her jaw dropping in disbelief. "....."

Then, as the realization hit her, she exploded. "....!!!"

"Fuck... you... Constellation!!!" she yelled, throwing up a middle finger at the status window in pure frustration.

"Why do I have to be stuck with this third-rate system? Why, why, why...?" she groaned, slamming her fists into the bed repeatedly, her earlier excitement replaced by sheer exasperation. Her carefully crafted plans had backfired, and now, she was left with nothing but her own annoyance.

Suddenly, another notification popped up on Esdeath's screen, interrupting her thoughts:

<Notification: Ethan has recognized your existence. Your worth has increased, but he is confused whether to take you as an enemy or a teammate...>

<For now, only 200 SP distributed.>

<Sylvia has recognized your existence. 100 SP points distributed.>

<Total SP: 1330>

<If you want to change the rules of the system, you'll need 100k SP.>

Esdeath stared at the screen, her emotions a mix of frustration and curiosity. "So, if someone is unsure about me or doubts my abilities, I get fewer SP points? That's something new," she muttered, frowning slightly.

She then focused on the last part of the notification. "And 100k SP points to change the rules of the system... Does that mean if I gather that much, I could make it so breaking the main storyline actually gives me SP points?" The thought made her eyes light up for a moment, but she quickly shook her head. "No point thinking about that now. I'm nowhere near 100k SP. Better focus on what I can do with what I have."

Determined to make the most of her situation, Esdeath turned her attention back to her current SP points. "Let's see what I can do with these 1330 SP points," she thought, a hint of excitement creeping back into her voice.
