Ruo Xiaoxi used the stair rail to make her way upstairs.

Her home wasn’t as nice as Xia Zhibai’s. It was just an ordinary sixty-square-meter apartment in the old part of town, on the fifth floor. Naturally, there was no elevator.

There wasn’t even a proper residential complex or property management. It was just the most ordinary neighborhood.

It wasn’t especially poor; her family was probably fairly well-off. Since she’d come here to attend high school, she was living here alone for now, while her parents and younger sister, who was still in middle school, lived in another city.

But she’d never heard of vampires living in this city!

Ruo Xiaoxi covered her stomach with one hand. It still felt as though something inside her had been stirred up and turned upside down, as if she’d eaten something bad. But she definitely hadn’t.

As a member of the vampire race, anything she ate was quickly converted into energy and absorbed into her bloodstream. It was very convenient—though nothing besides blood could ever make her feel full.

Oh, but she still had to pee after drinking water. There was no way to convert all of that away, too.

Hmm? Wait. If everything they ate vanished into energy, why did vampires still have a rear end? Was it just there in case they wanted to put it to use?

Vampires really were a pretty weird species (utterly confused).

Ruo Xiaoxi found herself thinking about this for no particular reason. She was being completely serious, though! She was just curious about vampire physiology. It wasn’t like any of this was covered in her biology textbook.

“I’m finally home.” Ruo Xiaoxi sighed with relief. She wondered if that little vampire girl had come to see her.

Her vampire big sister had promised to make time to visit her often, coming all the way from her own world. She was at least a somewhat responsible big sister—not the kind who’d turn someone and then leave them to fend for themselves.

Fun fact: supposedly, she was the little vampire’s only younger sister by way of the First Embrace.

Ruo Xiaoxi unlocked the door with her key. As soon as she stepped inside, she heard someone humming softly in the room.

It was a lovely girl’s voice, and she sounded cheerful as she hummed a tune Ruo Xiaoxi recognized—a melody from some recent pop song.

“You really did come over. And you’re hanging out in my room again.” Ruo Xiaoxi sighed.

You couldn’t tell whether anyone was home just by looking at the entrance. This little vampire never left her shoes by the door. She always flew in through the window, as if she’d decided that was the front entrance.

Ruo Xiaoxi took off her white sneakers, slipped on a pair of white bunny slippers, and headed into the living room. Tilting her head, she looked toward her bedroom door, which stood wide open.

Sure enough, a pair of elegant black high heels had been placed under the bed.

A beautiful girl was lounging against the headboard, playing with Ruo Xiaoxi’s game console. She had one leg resting across the knee of the other, with her foot cocked high in the air.

“Ah, little sis! You’re back!” The moment she saw Ruo Xiaoxi, she happily sat bolt upright.

Like Ruo Xiaoxi, the Vampiress had silver hair and red eyes, with a little bat-shaped hair clip. Her skin was very pale, and her face was breathtakingly beautiful.

Anyone seeing her for the first time would probably struggle to find words for her looks. She had the extraordinary, unmistakable beauty of the vampire race, with a distinctly European, Western feel.

That’s right. This was the little vampire who had given Ruo Xiaoxi the First Embrace: Chris Stasia.

Going by the way her name sounded, Ruo Xiaoxi had more or less figured it out. Most of the time, she called her “Big Sis,” though she also called her Chris.

At the moment, she was wearing an extremely revealing casual outfit. It had a bit of a little-succubus vibe.

“Um… Chris, could you please put on something a little more covering? There’s a girl in my bed wearing an outfit that’s way too revealing, and I’m almost afraid to come in…”

“How rude, you bratty little sister. This is what I wear at night after taking off my formal clothes. It’s meant to be worn at home. And since we’re at home, I should be able to dress a little more freely.”

“At least cover your butt!” Ruo Xiaoxi complained, eyeing the tiny triangle string panties Chris was wearing. They only covered the front, while the thin strip of fabric in the back did nothing to conceal the alluring curve of her perky little behind.

Sure, we’re at home—but this is my home, not yours!

“It’s been half a month since I last saw you. Why’s my little sister so cold? Aren’t you supposed to happily throw yourself into my arms and ask for a hug?” Chris rolled her eyes adorably and asked, looking thoughtful.

“I’m not your real little sister. You just forced me into your family tree in the middle of the night. So, what brings you back here this time?” Ruo Xiaoxi went into the room, sat down by the bed, and switched on her computer.

“I came to see how you’re doing, of course. I’m worried you might accidentally waste away one of these days.”

“That makes me sound like your pet.” Ruo Xiaoxi pouted.

“That’s exactly right. It’s my first time raising a pet little sister, so I can’t let you die. I have to check on you from time to time. If anything’s wrong with you, I can take a look.”

“Then just call me your pet. Don’t call me your little sister.” After hearing that, Ruo Xiaoxi felt strangely unhappy. It just didn’t sit right with her.

She didn’t care much about what people called her, but nobody liked being treated like a pet.

“Huh? Are you a little upset?” Chris looked unexpectedly awkward.

Ruo Xiaoxi didn’t answer. She just gave a few little huffs and opened her computer, getting ready to play a game.

When Chris saw that she was being ignored, she hurriedly scooted forward on her knees across the bed, rumpling the sheets. She leaned over the back of the computer chair and wrapped both pale arms around Ruo Xiaoxi’s neck.

“Aww, don’t be upset. I’ll give you a kiss, then. Mwah.” As she spoke, Chris gently pecked Ruo Xiaoxi’s soft cheek with her cherry-red lips, trying to cheer her little sister up.

Ruo Xiaoxi pretended to stay calm as she moved the mouse, but the kiss on her cheek made it turn faintly red…

Chris’s eyes gleamed with teasing amusement. She knew Xiaoxi was already embarrassed.
