I ordered a vampire online—Adrian. Hot, aloof. He was supposed to be my bodyguard and live-in housekeeper.

But he was always staring at my neck like he was starving. Fangs popping out, eyes glowing red.

And he was always walking around shirtless, wearing nothing but an apron. When I tried to stop him, he’d look all hurt and ask, "You don't like it?"

"But you're blushing."

I didn't know what to do, so I messaged customer service. They suggested, "You could form a bond with him. He'll be more obedient."

So I did. But I had no idea I was forming a two-way mate's bond instead of a one-way master-servant bond.

The night we bonded, he climbed into my bed, eyes glowing red. He licked my skin, hungry, grinding against me desperately and begging, "Master, just one bite, please? I'll make you feel so good..."

To help with my daily life and for my own safety, I ordered a powerful, handsome vampire online. But he seemed to have a few… defects. He was always staring hungrily at my neck, his fangs would appear without warning, and his eyes would flash red. It wasn't until later that I realized he wasn't sick—he was just hungry in a way that had nothing to do with blood.

"Are you sure you want to order this one?"

The app's customer service rep sounded hesitant. "This vampire is a bit… special. His needs are very strong. I’d recommend a model with a gentler temperament."

I was confused. "Strong needs? Like, from psychological trauma?"

"You could say that," the rep replied vaguely.

"Then it's no problem," I said, decisively tapping ‘Confirm Payment.’ As a psychologist with eight years of practice, a creature with deep-seated psychological issues was basically my catnip.

Besides, that psychopath had started following me all the way to my front door. I needed a two-for-one deal: someone who could protect me and handle the chores. After the Supernatural Beings Legalization Act, hiring vampires as bodyguards had become pretty standard for humans.

The payment-successful notification chimed.

Three hours later, my doorbell rang.

I opened the door and froze.

A man stood in the hallway, at least six-foot-three, dressed in a black straitjacket, its silver buckles glinting in the light.

His head was bowed, dark brown hair obscuring half his face, but it couldn't hide his impossible beauty—pale skin, a high-bridged nose, thin, firm lips, and eyes that were currently fixed on the floor.

"Master," he said, his voice low and raspy.

"Just call me Chloe." I stepped aside to let him in.

He walked stiffly into the living room and stood motionless. I circled him.

His build was definitely impressive. Broad shoulders, a taut waistline, and the clear outline of muscles beneath the straitjacket. He gave off an aura of pure security.

I nodded, satisfied, then stepped in front of him and gently took his chin in my hand. "Open your mouth. Let me see your teeth."

I leaned in, so close I could almost feel his cold breath.

His body went rigid.

The next second, his irises began to bleed into red. Sharp fangs descended from his gums, and a low whimper escaped his throat, a sound torn between pain and desperate need.

I jumped back, startled, thinking my actions had scared him.

"Shh, it's okay," I whispered, releasing his chin and patting his shoulder gently.

I didn't expect the gesture to make him tremble even more.

His crimson eyes were locked on me.

Drawing on my clinical experience, I had an answer. This must be what the rep meant by "strong needs": a craving for physical contact, a lack of security. It looked like a classic case of skin hunger.

As a competent psychologist, I knew exactly how to soothe this kind of patient.

I opened my arms and pulled him into a hug.

His body was stiff for a moment, but then he melted into me, burying his head in the crook of my neck, his breath coming in soft, broken gasps.

"It's okay. I won't judge you," I said, patting his back like I was comforting a child. "You'll live here from now on. Work hard, and I'll take care of you."

He didn't speak, but I could feel his arms tightening around me.

To distract him, I gently pushed him away and took his hand, leading him toward the balcony. "Come on. Let's find you some… strenuous work to do."

His body went stiff again.

I opened the balcony door and turned back to look at him.

He was blushing. A faint crimson washed over his pale, almost translucent face, and the red in his eyes deepened.

"Here?" he asked, his voice hoarse. "What if someone sees?"

I blinked, then grabbed a mop and cleaning solution from the utility closet and shoved them into his hands.

"Sees you cleaning? What's the big deal?"

"Alright, you can start with the balcony."

He looked down at the mop in his hands, the blush instantly draining from his face. His eyes returned to their deep brown, and his fangs retracted.

His expression shifted to one of pure, bewildered shock. "You bought me to do chores?"

"You bought me to do chores?"

Adrian stood on the balcony, mop in hand, his voice laced with disbelief.

"Of course not!" I shook my head, looking at him seriously.

His eyes lit up.

"You're also my part-time bodyguard. You have to keep me safe," I said, patting his arm. "I've been dealing with a stalker lately, and I need protection. You're strong, well-built, and I hear vampires are powerful fighters. It's a perfect fit."

His head drooped again.

For a second, he looked less like a vampire and more like a big, sad dog, his ears flopping down.

"Also, I'm too busy with work to do housework," I added, pointing at the dust and piles of laundry. "I'll be counting on you for all this."

He lowered his head silently and started mopping.

Maybe he was trying to prove his worth, because he suddenly moved with vampire speed, becoming a blur as he zipped across the balcony.

Then came a deafening CRASH.

My antique vase lay in a thousand pieces.

Adrian stood in the middle of the shards, looking at me with a miserable expression.

"I'm sorry, I'm so sorry..." He bent down to pick up the pieces, cutting his finger on a sharp edge.

"Don't move!" I grabbed his hand. "The vase doesn't matter. Don't hurt yourself."

He looked up at me, his eyes filled with anxiety. "Are you going to send me back?"

"Of course not," I sighed. "Just take your time. There's no rush."

Over the next week, Adrian learned quickly.

He figured out the dishwasher, learned how to sort recycling, and even managed to make simple meals. Though he didn't need to eat, he always had dinner ready for me when I got home from work.

Every night, he'd be waiting outside the hospital to walk me home, silently following three steps behind me.

The stalker never showed up again.

I was more than pleased with him.

The only awkward thing was how he always stared at my neck.

Every time I turned my head, I'd catch him with his eyes turning red, his breathing shallow, fangs peeking out from between his lips.

And he never wore a proper shirt at home, always doing his chores shirtless, with just an apron to cover him.

"Adrian, please put a shirt on," I said, pointing at his bare chest.

"But it's hot in here," he said, looking down at himself. "And I'm just cooking in an apron. It’s not like I’m completely naked."

"That's not the point!"

"But I read online that humans like this," he said, confused. "You don't like it?"

I was about to give him a firm 'no' when he leaned in closer, his voice a low, seductive murmur. "But I see you blush every time."

"Th-that's just a normal physiological reaction!" I turned my face away. "Anyone would blush at a sight like that!"

"So you admit you like it?"

"...Put a shirt on."

He smiled and obediently went to his room to get dressed.

But he came back wearing only a thin, white button-down, with only the bottom two buttons fastened.

"Is this better?" he asked, his face a perfect mask of innocence.

I completely surrendered.

What was even more awkward was that several times, when I got up in the middle of the night to use the bathroom, I could hear his suppressed moans coming from the shower.

My professional instincts told me his skin hunger was getting worse. I must have been too busy with work and had neglected his psychological needs.

To make up for it, I decided to let him sleep with me tonight.

"Adrian," I said, sitting on my bed and patting the space next to me. "You can sleep here tonight."

He stood at the door, his eyes greedily sweeping over my bed. "Can I really?" he asked, his voice raspy.

"Of course," I said, lifting the covers. "Come on."

He carefully climbed onto the bed, lying stiffly on top of the covers, keeping at least two feet of distance between us.

"Don't be so formal." I just went for it and wrapped my arms around him.

His body was cool, like a walking ice pack. On this stuffy summer night, he was a natural air conditioner.

"So cool," I sighed contentedly, burying my face in his neck.

His whole body went completely still.

I quickly drifted off in the comfortable chill, completely oblivious to his ragged, heavy breathing.

I was jolted awake by a searing heat.

Adrian's body temperature had skyrocketed. He was holding me tight, his face buried in the side of my neck, his breaths so ragged he sounded like he was suffocating. His body was trembling, and he kept grinding against me.

I became acutely aware of what was pressing hard against my thigh.

My face flushed, and I quickly pulled my leg away.

"Adrian?" I nudged him. "Are you not feeling well?"

He didn't answer, just held me tighter, a low whimper vibrating in his throat.

I immediately grabbed my phone and messaged the app's customer service.

"Hi, the vampire I purchased has been acting strange. Is this a quality issue?"

The rep replied instantly. "Is he being disobedient? Are you unsatisfied?"

I thought about Adrian's behavior lately. The not wearing clothes, always staring at my neck, constantly trying to sniff me…

"He's not exactly being obedient," I typed back.

"We recommend establishing a blood bond as per the user manual. The vampire will become completely subservient to your commands."

I closed the chat and immediately dug out the thick manual from my nightstand.

The next morning, Adrian was back to normal, calmly making breakfast as if nothing had happened.

I walked up to him with the manual. "Adrian, I want to establish a blood bond with you. Are you willing?"

His hand trembled, and the plate he was holding almost fell. He spun around, his eyes flashing red again as he stared at me in disbelief. "What did you say?"

"A blood bond," I said, opening the manual and pointing to the instructions. "This way, you can take better care of me, right?"

The manual described two types of bonds: a one-way bond and a two-way bond. The two-way bond promised higher loyalty, so I decisively chose that one.

What I overlooked was the fine print at the bottom: One-way bonds are for master-servant relationships, while two-way bonds are typically used between mates.

A two-way bond is unbreakable. The bonded pair share a life and a soul.

Adrian seemed to be getting agitated again, his breathing quickening, his fangs peeking out.

It seemed like bonding was absolutely necessary.

"Are you willing?" I asked again.

"Yes! I am," he answered instantly, as if afraid I'd change my mind.

Following the instructions, I used a silver knife to prick my finger and offered the blood to his mouth.

His tongue curled around my fingertip. It tickled, and I couldn't help but flinch. Adrian's tongue followed, wrapping tightly around my finger.

Then, he bit his own wrist and held it to my lips.

I frowned but drank. His blood was cold and had a strange, sweet taste. A jolt like an electric current shot through my entire body.

Suddenly, Adrian pinned me against the wall, his hands on either side of my head, the red in his eyes practically spilling out.

"I'm yours. Forever," he whispered in my ear.

I froze. Something felt off, but before I could think about it, my work alarm went off.

"I have to get to work," I said, pushing him away and rushing to get ready.

That night, I had just gotten out of the shower and into bed when Adrian appeared in my doorway.

His eyes were crimson, and he was wearing only a pair of sleep pants, his lean, muscular torso on full display.

He walked to the bed, climbed right on top of me, and trapped me under his body.

"Chloe," his voice was impossibly hoarse, and he seemed more desperate than ever. "It hurts."

He lowered his head, his tongue tracing a path over my collarbone. "I need to bite… just once."

My whole body tensed up.

I immediately grabbed my phone and opened the chat window.

"Customer service! What is going on? I did the bond like you said, but he seems even worse!" I typed furiously, explaining the situation.

The rep's reply came back, filled with undisguised shock. "Are you saying you formed a two-way blood bond with him?"
