《Cash Rules Everything: My Infinite Wallet》

Unlike the snake pits of most girl dorms, Chen Guo's quartet operated like a precision Swiss watch—all gears interlocking without friction. As the baby of the group with her lamb-soft innocence and mysterious family background, Chen Guo had unwittingly become the dorm's collective treasure.

Which explained why Su Li's internal alarms blared when she saw Chen Guo giggling with this "nephew".

"Thanks for watching over our little dumpling," Su Li said, smile polished to surgical steel.

"Old hometown duty." Lu Yuan's shrug was artfully careless until his phone vibrated—Waldorf Astoria's concierge. Three sentences later, he gestured toward the exit: "Our ride's here."

Su Li dragged Chen Guo into a conspiratorial lag. "Spill. Since when do you keep pet nephews?"

"It's... an inside joke!" Chen Guo's earlobes betrayed her, glowing like nuclear reactor rods. The abbreviated train tale spilled out between suppressed giggles.

Su Li's eyebrows climbed. "My pure little lotus flower's playing aunt-nephew roleplay? Should've lent you my '50 Shades of Grey' annotated edition sooner."

"Su Li!" Chen Guo's shriek drew stares as she launched a tickle assault. Their scuffle halted abruptly when sunlight caught Lu Yuan's wrist mid-stride.

"Hold!" Su Li gripped Chen Guo's shoulders. "That watch—Patek Philippe Celestial?" Her manicured nails danced across her phone. Search results bloomed: "$2.8M...waitlist 8 years..."

Chen Guo's gasp could've sucked oxygen from the station. She stormed toward Lu Yuan, grabbing his wrist like confiscating contraband. "You let me flail like an idiot about the bald guy?!"

Lu Yuan's grin turned vulpine. "Technically, you never asked about the watch."

His captured hand became a live wire. Chen Guo recoiled, porcelain cheeks achieving Chernobyl-level meltdowns. "You...you...!"

"Truth serum time." Lu Yuan leaned in, breath stirring her bangs. "Yes, I enjoyed watching you puzzle it out. Yes, your outrage is..." His gaze dipped to her heaving chest. "...educational."

Su Li's snort detonated the tension. Chen Guo became a pink meteorite chasing Lu Yuan across the station, her combat boots clacking like castanets. "One hundred 'aunties' or I'll—"

Her threat died as Lu Yuan halted beside automotive royalty—a Rolls-Royce Phantom bleeding shadow and chrome.

"Lu Yuan?" The chauffeur's gloved salute could've come from Buckingham Palace.

Su Li's jaw met floor tiles. Chen Guo's windmill arms froze mid-swing. The universe held its breath.
