(The female lead is officially online!!! There are pictures! Pictures!! Pictures!!!)

In the evening, as Gu Jin arrived at his doorstep, his fingertips touched the cold doorknob, and his heart tightened—the lock cylinder seemed to have subtle pry marks, clearly tampered with.

A scent that wasn't his permeated the air; the familiar smell of his home seemed to have faded, leaving only a strange, lingering stagnation.

Gu Jin instantly shed his relaxed demeanor, his aura tensing abruptly, his footsteps becoming extremely light, almost silent.

His living space wasn't large; the one-bedroom, one-living-room layout was clear at a glance, but at this moment, every shadow seemed to hide an undercurrent.

His gaze swept across the living room; the simple sofa and coffee table were just as he had left them, but from the crack in the bedroom door, a faint glow subtly leaked out.

Someone was hiding in the bedroom.

Gu Jin's fingertips unconsciously curled as he slowly moved towards the bedroom door. Just as his finger was about to touch the door panel, a female voice suddenly drifted out from within—

It wasn't a sharp warning, nor was it deliberately cold and hard; instead, it was like a jade bead soaked in warm water, clear and moist with a hint of crispness. It was indescribably pleasant to the ear, like a cool spring or an evening breeze, light enough to be captivating, yet clear enough to be impossible to ignore.

"You're back?" The female voice paused, with a hint of a smile that wasn't quite a smile, "Not bad, your vigilance is quite high."

Chinese?

Gu Jin's heart stirred. Before he could think further, the bedroom door was gently pushed open from the inside.

A figure leaned against the doorframe, the warm indoor light falling on her, outlining a slender yet upright silhouette.

Her long hair was not tied up, falling loosely over her shoulders, the ends with a natural curve, a few wisps clinging to the side of her fair neck;

Her bangs were neatly trimmed, perfectly revealing her full forehead, and a pair of eyes that shone like they were steeped in starlight—the outer corners slightly upturned, yet without any sharpness, instead revealing a hint of casual liveliness.

She wore a simple white shirt, the top two buttons undone, revealing her delicate collarbone. Her lower half was a pair of dark jeans, the cuffs casually rolled up to her ankles, exposing a section of her fair calves.

Though the clothing was the most ordinary, it looked exceptionally harmonious on her, possessing both a crisp, dashing air and the unique youthful charm of a girl. Standing there, it was as if even the indoor light was drawn to her, making her so radiant that one couldn't tear their eyes away.

"Who are you?" Gu Jin's voice instantly deepened, his fingertips unconsciously clenched, his tense sense of vigilance undiminished as his gaze remained fixed on the woman before him.

Ling Fei'er didn't rush to answer. She reached into her jeans pocket and pulled out a dark blue document—the gold-embossed 'International Criminal Police Organization' emblem on the cover was exceptionally clear in the warm light. She gently opened it, revealing the photo and information inside.

Gu Jin focused his gaze, and the words "Intermediate Officer—Ling Fei'er" prominently appeared before his eyes.

International Criminal Police?

Gu Jin's heart sank abruptly, his brow furrowing into a tight knot: Could Uncle's case have become so serious as to require the intervention of Interpol?

"Are you here to arrest me?" His voice dropped a few more octaves, carrying an imperceptible chill, his Adam's apple subtly bobbing, clearly wary of this sudden "visit."

Upon hearing this, Ling Fei'er's lips curved into a smile that wasn't quite a smile. Her eyes, bright as if steeped in starlight, curved slightly, and her tone carried a hint of casual probing: "What? Have you done something illegal that makes you feel guilty?"

Gu Jin's expression remained unchanged as he directly pressed on: "Is it not because of my Uncle's matter?"

The smile in Ling Fei'er's eyes faded slightly, and her tone became more serious: "Gu Jin, regarding your Uncle's case, I cannot disclose the relevant details to you for now.

However, my mission this time is not to investigate, but to protect your safety—for a period of one year.

Furthermore, to avoid arousing suspicion, for the next year, I will live with you as your girlfriend."

"Protect? Girlfriend? Live together?" Gu Jin's pupils contracted slightly as he repeated three phrases in a row, his tone filled with shock and disbelief, clearly not expecting such a response.

"What? Surprised?" Ling Fei'er raised an eyebrow, her tone teasing. She lightly tapped the document in her hand, but her gaze was fixed on Gu Jin's reaction.

Gu Jin didn't reply, the wariness in his eyes intensifying: "But why should I believe you? Just based on a document whose authenticity I can't even verify?" He reached out and pushed the document back, his fingertips carrying a deliberate sense of distance.

"Quite good, actually," Ling Fei'er chuckled softly, not getting angry. Instead, she put the document away in her pocket. "I knew you wouldn't believe it easily. Come with me, let's go see someone. She can make you believe."

"Before things are clear, I'm not going anywhere." Gu Jin took half a step back, his back pressing against the cold wall, adopting an unyielding stance, his aura growing even colder.

Ling Fei'er 'tsk'ed, shaking her head helplessly. She raised a hand to brush aside the long hair by her ear, revealing a black intercom earpiece hidden behind it, and spoke lightly into the microphone: "There's really no other way. Do it—just stun him, don't break him."

No sooner had her voice fallen than two dark figures suddenly darted in from outside the door, heading straight for Gu Jin!

Gu Jin was prepared. He sidestepped the first person to rush him, his arm wrapping around the opponent's arm with the momentum. He used his core strength to swing, and with a muffled 'thud,' the person was directly thrown over his shoulder onto the ground, groaning in pain.

The other person rushed forward upon seeing this but missed, stumbling and nearly hitting the coffee table.

"You're quite a handful." A flicker of surprise crossed Ling Fei'er's eyes, quickly followed by a hint of interest. Before her words even finished, she had already lunged forward with astonishing speed, leaving almost only an afterimage.

By the time Gu Jin reacted, she had somehow acquired a silver-grey stun baton, emitting a faint electric hum.

Gu Jin's pupils contracted sharply. Just as he was about to sidestep, Ling Fei'er's movements were faster than he anticipated—she subtly shifted her feet, her body pressing against him like a wisp of smoke, her wrist slightly dropping, and the stun baton precisely touched Gu Jin's waist.

With a soft 'buzz,' a subtle current instantly coursed through his limbs.

Gu Jin felt his entire body go numb, his muscles suddenly losing strength. His previously tensed arms dropped heavily, and the scene before him began to spin. Ling Fei'er's playful face gradually became blurry.

He tried to steady himself against the wall, but his fingertips lacked even the strength to touch it. His knees buckled, and his body uncontrollably fell forward.

Ling Fei'er was quick, wrapping her arm around his waist and steadily supporting him.

The last shred of Gu Jin's consciousness remained, and he heard her chuckle softly near his ear, her tone teasing: "Disobedient? Had to make your sister shock you? Do you have a masochistic tendency?"

As her words finished, Gu Jin's vision plunged into complete darkness, his body limp as if boneless, and he completely fainted.

The two people who had just gotten up nearby quickly came forward: "Ling Team Leader, what now?"

Ling Fei'er looked down at the unconscious Gu Jin in her arms, then reached up to smooth his messy hair from his forehead, her tone regaining some calmness: "Get him into the car, carefully. Don't let him get bumped or bruised—he's our 'key protection target' for the next year."
