Fantasy

Step 1: Inherit a creepy old mansion.
    Step 2: Unlock a cursed system that makes girls fall dangerously in love with you… just by saying “hi.”
    Step 3: Learn that if you don’t reject them within 10 texts, something terrible happens.
    My name’s Ren.
    And apparently, I’m the “Catalyst for Affection-Based Catastrophes.”
    (Yeah. That’s literally what it said.)
    My peaceful new life? Over.
    Now I’m stuck in a house full of magically unstable girls:
    A sword-swinging elf.
    A fire mage with zero personal boundaries.
    A strict class rep who faints if I so much as look at her.
    And a witch who cursed the bathroom mirror to spy on me.
    They’re beautiful.
    They’re powerful.
    They’re dangerously obsessed.
    And if I mess this up, someone’s going to get hurt—maybe me.
    Reject them too late? Game over.
    Fall for one of them? Even worse.
    This isn’t a dating sim.
    It’s survival of the cutest.
    Welcome to my life. It's not just a harem. It's a hostage situation.
