1:17 AM. Lin Wan’s fingers scrolled absently across her phone screen. The exhaustion from overtime work draped over her like a thin veil, yet an unnamed restlessness prickled beneath it. In the hum of the air conditioner, her gaze was suddenly caught by an ad—a sleek, artfully designed electric  Remote-controlled female electric vibrator rotating under soft light against a black background, accompanied by the words:  "Changwang · Your Smart Companion."  

 

"Adjustable temperature, ten vibration modes, AI learns your sensitive zones…" Her ears burned. Instinctively, she glanced around her empty apartment, as if the words might leap from the screen and be seen by invisible eyes. Her thumb hovered over the  "Buy Now"* button for three seconds before she settled for adding it to her favorites instead.  

For the next three days, that black icon sat in her collection like a pebble in her shoe, impossible to ignore. On Friday night, when Lin Wan opened the product page for the third time, a user review caught her eye:  "It remembers the rhythm that brings me to the edge—like a lover who truly knows my body."  The words sent a pulse of heat low in her stomach.  

 

When the payment confirmation chimed, she buried her face in a pillow and laughed. A thirty-year-old marketing director, commanding meetings with sharp efficiency—who would guess her heart raced over an AI-powered  toy ?  

 

The package arrived on Tuesday afternoon. The dark gray gift box bore only a silver feather emblem, discreet as a luxury skincare product. Lin Wan tucked it into the deepest corner of her briefcase, and as the zipper closed, she felt as though she were sealing away a delicious secret.  

 

Steam fogged the bathroom mirror after her shower. Lin Wan wiped it away, revealing her reflection—eyes glistening, droplets still clinging to her collarbone. She took out the  "Changwang."  Under the dim light, its pearlescent curves fit perfectly in her palm, as if molded for her alone.  

 

 "First-time users are advised to start at the lowest setting…"  The instructions suddenly blurred before her eyes. She took a deep breath and pressed the dark red button at the base. The motor purred to life, softer than expected—like distant ocean waves. When the first vibrations traveled up her fingers, her teeth sank into her lower lip.  

Then, in  smart mode , something remarkable happened—the pulses were no longer mechanical but ebbed and flowed with her breathing. When her grip tightened unconsciously, the rhythm responded instantly, as though reading her body’s subtlest cues. A wave of emotion surged in her chest. This wasn’t just pleasure; it was  understanding .  

 

Afterward, Lin Wan curled into her silk sheets, watching the  Nightingale  pulse with a faint blue glow on its charging dock. In the past, this moment would have been hollow. Now, a quiet satisfaction hummed through her. She brushed a finger over its smooth surface, and the device vibrated twice in reply— I’m here.   

 

The next morning, her app notified her:  "Based on initial usage data, your custom mode 'Evening Breeze' has been created."  She locked her phone, cheeks warm, but couldn’t suppress a smile. On the subway, her reflection in the window showed her outfit—a dark green silk blouse, fastened with a silver feather brooch.  

 

At the office, an intern blinked up at her.  "New perfume, Ms. Lin? It suits you."  She only smiled. No one knew that beneath her tailored skirt, her thighs still tingled faintly from last night. Or that the black device in her nightstand’s third drawer now held every secret her body had ever whispered.  

 

That weekend, rain lashed against the windows. Lin Wan traced the  "Remote Control"  option in the app, barefoot on the rug. On her screen, a message from her college crush glowed:  "Dinner tonight?"  She lifted the phone to her lips.  "Can’t. I have plans."  From the bedroom, a familiar vibration answered—the Nightingale, calling back to its owner.
