Unexpected Guests Undertale

I transmigrated into a dating-sim otome game where I was supposed to romance a soft, fragile male lead. I had finally pushed him onto the bed and was just about to make my move when the long-missing system finally popped back online. [Host, I sent you to the wrong game. This is a horror game.] [The man you’re bullying right now is the horror game final boss.] I lifted my head and met a pair of blood-red eyes staring straight at me. My smile froze. “Um… you look a little tired. Maybe we should… continue this another day?” He smiled back, calm and terrifying. “I’m not tired. Go on.”

After entering a horror game, I, Anastasia Moreau, begin dating the big boss. At our first meeting, I wrap my arms around his sleek, serpentine body and squeeze him into a corner of the coffin. "Move over, move over." In the next instant, a strikingly handsome young man with white hair and golden eyes appears beneath me. The tips of his ears flush red as he glares at me. "You… You're lying on my hair!" he grits out.

For the sake of that fake heiress, my biological parents and brother threw me into a horror game to "teach me some manners." The second the game started, the fake heiress, Nicole, went out of her way to provoke the ghosts nonstop. Once she'd pissed them off, she shoved me in front of her to take the punishment. As I lay there, tortured within an inch of my life, she planted her foot on my head and smirked. "Mom and Dad already made it clear—I'm the only one they truly love. They only brought you back to keep me entertained! Letting you deal with those ghosts for me is more than generous. If you dare complain, once my brother and the others get back, they'll skin you alive." In my past life, I treated them like family and gave in every single time. In the end, I was nothing but a stepping stone for them to beat the game—torn apart and devoured by over a dozen ghosts. But now, I've been reborn. "Welcome to Horror Instance: Happy Home." The moment I heard that mechanical announcement, I slapped the arrogant Nicole so hard she flew across the room. Because in this instance, the three bosses that terrorized every player… were all my family. The red-dressed female ghost who killed without hesitation was my adoptive mother. The monster with scissors for hands who ripped out hearts with a single swipe was my adoptive father. And the ruthless warden who devoured people whole, leaving no bones behind, was my adoptive brother. With them watching my back, why the hell would I keep putting up with this? A mocking smile curled across my lips as I said, "You're on my turf; none of you are getting out alive."

The day I was supposed to win the biggest award of my career, I walked in on my boyfriend, Ethan, in bed with another woman. He sneered, calling me a face-blind, scent-deaf bore in bed. I planned to expose his ass at the award ceremony. Instead, he and his lover mowed me down with their car. Next thing I knew, I woke up with them in an S-class horror survival game. Mortality rate: over 95%. We had to survive ten days in a haunted manor to be revived. Hit 100 on your Anxiety Level, and your soul is obliterated. Chloe, Ethan's lover, sneered. "Sensory defects? You can't recognize ghosts or smell danger. In a horror game, that’s a death sentence. You might as well just die." The others heard her and scrambled to team up. Me? I walked straight into the lair of the manor's final boss. The most powerful demon in the game wanted to devour my soul. I couldn't really see him. I just thought he was a cosplayer. I lunged forward, poked his abs, and pointed at the glowing crack in his chest. "Wow, you're really committed to the role. This getup must've cost a fortune."

I was always sick as a kid. My parents were desperate. They’d try anything. So they got me a bunch of "guardian angels." Next thing I know, I'm set up and tossed into a horror game. Turns out, Medusa is my godmother. The ghost girl? My childhood playmate. And the final boss, a vampire? He's my fiancé. The first time we met, I was in a blind panic. I tripped and fell right onto his chiseled chest. "Oh—I'm so sorry! I wasn't looking—" I gasped, looking up at him. The words tumbled out in a rush. "And you're really handsome—but I didn't mean to fall on you! I have a heart condition!" The boss let out a laugh. He wiped the blood from his hands and swept me up into his arms. "Don't you worry," he purred, his voice dangerously smooth. "As your fiancé, I promise... I'll fix you right up."

I am a miserable nurse. During the Halloween season, there was a three day break but I was not given any days off. Upset, I decided to join a game featuring a haunted hospital. There was an old man wrapped in IV tubes chasing after a player. I sprinted forward and shoved him into the chair. After effortlessly jabbing the IV line back in him, I told him off, "It’s just an IV drip, not an action movie. Sit. Down. Move again and I’ll strap you to the chair!" The old man did a double take before blinking in a flustered manner. "Sorry for causing you trouble, ma'am." At night, children ghosts began to run and laugh wildly in the corridor. I grabbed one in each hand and hauled them up. "If you’re not going to stay put in the ward, I’ll give you an injection!" Why did I still have to work in a game? I was so tired. The other players cried out, "Clem! That's a ghost. Are you not scared?" I sneered, "Sorry, but burnt-out workers hold more grudges than ghosts ever could."
