Supervillain Idol System: My Sidekick Is A Yandere

The light coming through the windows cast a glow over the trio as Don's eyebrow arched upward, his gaze shifting between Hector and Tori's features. The resemblance was minimal at best, save for their shared dark hair.

"You two are siblings?" Don asked, tilting his head slightly as he leaned back in his chair.

Before Tori could open her mouth, Hector slid into the empty seat between them with the grace of a cat, his chain necklace jingling softly. "¡Sí, hermano! She's my little sister," he beamed, gesturing between them. "Same mom, different dads."

**Screech** The metal chair legs scraped against the floor as Hector scooted closer to Don, his voice dropping to a conspiratorial whisper. "Mi amigo, if you told me you like Latina girls, I would've set you up with the baddest chicas in the city, instead of my boring sister. I'm talking pretty face, hips that don't lie, big boot-"

**Thwack**

"¡Ay, carajo!" Hector suddenly jerked back, rubbing his shoulder where Tori's fist had just connected.

"¿Qué diablos, Hector? Shut up, or I'll tell mom about your little neighborhood business!" Tori's cheeks flushed red as she crossed her arms, glaring at her brother.

"No, no, hermanita!" Hector laughed nervously, attempting to drape his arm around her shoulders. "Era una broma, I promise!" His chain swung wildly as he quickly pivoted toward Don, his eyes lighting up. "Anyway bro, I watched your performance yesterday. I was incredibly impressed. How would you like-"

**Thump**

Tori's palm connected with Hector's face, pushing him away. "Oh my god, Hector, can you please go?" She groaned, slumping back in her chair. "Not everything is a business opportunity. Can't you see we're just trying to talk about normal stuff?"

Don maintained his smile, watching the siblings' interaction with growing amusement. He drummed his fingers on the table before nodding. "Tori's right. I'm just here to relax."

'Well, since he's Tori's brother, I'm going to have to associate with him one way or another if I decide to keep a friendship with her,' Don thought, studying Hector's animated features.

Hector's shoulders slumped dramatically as he pushed his chair back. "Fine," he sighed, placing a hand over his heart. "Since mi propia hermana does not want me here, I shall leave." He rose slowly, each movement exaggerated for maximum effect.

Tori rolled her eyes, focusing intently on stirring her drink with her straw.

Don reached out, gesturing for Hector to stop. "No need to leave," he said, maintaining his pleasant expression. "I just don't discuss business anyhow." His fingers traced abstract patterns on the table's surface as he spoke.

Don watched as Hector settled back into his seat, adjusting his chain necklace with a casual flick.

A chubby waitress with thick-rimmed glasses and metal braces then approached their table, her ponytail bouncing slightly as she walked. Her name tag read 'Jenny', and she clutched her notepad close to her chest.

"¡Hola hermosa!" Hector leaned forward, flashing his trademark smirk. "Looking especially radiant today. Any chance of hooking us up with that special discount?"

Jenny's cheeks flushed red as she adjusted her glasses. "I-I'm sorry, Hector. Mr. McDaniel specifically said no more discounts for you."

"Ay, come on," Hector gestured toward Don. "I brought such a big customer today. Surely that counts for something?"

"Rules are rules," Jenny mumbled, clicking her pen nervously.

Don observed this exchange with careful attention, noting how Tori rolled her eyes at her brother's antics.

His decision to allow Hector to stay wasn't arbitrary - Tori's relationship with her brother, despite its apparent friction, could be valuable. Moreover, Hector's presence made the situation appear less intimate, and Don couldn't dismiss potential future benefits of this connection either.

They placed their orders - burgers and fries all around. After a short wait, the food was served to their table.

As they ate, Hector dominated the conversation, his hands moving animatedly as he spoke.

"So there I was, ¿verdad? This guy thinks he can outsmart me on the deal, but-"

"That's not how it happened," Tori interrupted, pointing a fry at him. "Mamá told me you barely broke even."

"Ay, hermanita, why you gotta do me like that?" Hector clutched his chest in mock pain, maintaining his easy smile. Your journey continues with empire

Don maintained an expression of engaged interest, nodding at appropriate moments while his mind worked overtime. He studied their mannerisms - Hector's confident posture versus Tori's more defensive positioning, the way they unconsciously mirrored each other's gestures despite their bickering.

**DING** **DONG**

Suddenly, a soft, robotic feminine voice echoed through the fast food place, coming from outside: "Attention all students and visitors. The evaluation for the first batch of regular incoming students will begin shortly. Please make your way to the stadium now and take your seat to avoid crowding further on."

"¡Mierda!" Tori jumped up, nearly knocking over her drink. "It's time already! I need to go get changed."

Hector leaned back, crossing his arms behind his head. "Yes, you better hurry. Don and I will go find seats, right bro?"

Don shook his head, straightening his posture. "Unfortunately, I can't. I have something to take care of in the afternoon, so very soon."

Tori waved toward Jenny. "Check, please!"

"I'll handle it," Don reached for his wallet.

"Ah, a true gentleman," Hector chuckled, settling more comfortably in his chair.

"You could pay too, idiota," Tori crossed her arms, glaring at her brother.

Hector spread his hands innocently. "I wouldn't want to be rude since you both offered, hehe."

"Bastardo," Tori muttered, then turned to Don with a softer expression. "Thanks, and sorry for my dumb brother. I'll text you once my evaluation's done."

"No problem," Don replied, maintaining his pleasant expression. "Good luck."

As the siblings departed, Tori practically jogging toward the exit while Hector sauntered after her, Don watched them go, mentally filing away every detail of their interaction for future reference.

Elsewhere, the lunch bell's shrill ring echoed through the halls of Nexus Academy, signaling a brief break from the day's academic rigors.

Summer was slouched in her chair at the back of the classroom, one leg crossed under her desk as she scrolled through her phone. Beside her, Sylvia had claimed ownership of the adjacent desk's surface, perching herself on top with her legs swinging against its metal frame.

**tap** **tap** **tap**

Their fingers were busy at work tapping on their phone screens in comfortable silence until the shuffle of hesitant footsteps drew near. A group of male classmates approached, their shoes scuffing against the floor as they awkwardly shifted their weight.

"Hey, uhm, Summer," one of them started, his eyes fixed on the ground. "If you need anything from the cafeteria then-"

Summer didn't even lift her gaze from her phone. This had been the pattern all day - students who'd never given her a second glance suddenly materializing with offers of friendship and favors.

Her thumb continued scrolling through Delaygram until a particular post made her pause.

There it was - Don seated at a Mcburger table, his signature charming smile directed at Tori, who sat across from him with a shy blush painting her cheeks. The caption beneath made Summer's stomach turn:

"Does our city's new rising star already have a soulmate? #couplegoals #Herolove"

Summer's fingers tightened around her phone as her face twisted into a deep scowl. tch Her tongue clicked against her teeth in irritation.

"I'd like a 'can you leave me alone?'" she snapped at the hovering boys, her voice harsh. "Geez, fuck."

The group scattered like startled pigeons, their rapid footsteps echoing down the hallway. Sylvia couldn't help but as she watched them retreat.

"They really ruffled your feathers, huh?" Sylvia observed, but her amusement faded as she noticed the unusual intensity of Summer's frown. As Summer's best friend, she'd witnessed countless expressions of teenage angst from this friend of hers, but this seemed different.

Sylvia hopped down from the desk, her uniform skirt swishing as she landed. She then leaned forward, invading Summer's personal space as poked her cheek with one perfectly manicured finger.

"Hey, why so grumpy?"

Summer's shoulders tensed as she turned away, her blonde hair falling forward to shield her face. "I don't care."

"Care about what?" Sylvia pressed, tilting her head with exaggerated curiosity.

A hint of pink crept across Summer's cheeks as she abruptly pushed back her chair, the legs scraping against the floor. She then quickly grabbed her bag, clutching it close to her chest like a shield.

"Nothing!" she declared, her voice pitched slightly higher than normal. "Let's just go eat already."
