After graduating from college, I ended up unemployed at home. My love life had always been a mess, and I kept hitting dead ends in my job search. Just when I was broke and barely scraping by, I met my current girlfriend.
She treats me wonderfully, truly wonderfully. She works outside the home and doesn't mind at all that I'm idle at home. Her only request is that I love her. I might as well be her kept man. Her unconditional love makes me feel incredibly lucky, as if I'd been blessed beyond measure.
It's just that she seems a little strange...
She'll suddenly leap up in the middle of the night and choke me because she dreamed I was kissing another girl.
If she sees me talking to another girl on the street, she'll rush over and slap her right there.
When she asks how many ex-girlfriends I've had, she secretly pinches the soft flesh around my waist.
She'll snoop through my phone, then contact any girl who's been looking for me and set up an in-person meeting just to cause trouble.
She's a little strange, a little unreasonable.
But I know everything she does is because she loves me.
Then one day, when my ex-girlfriend asked me to meet her, I suddenly awakened the Yandere Simulation Reality System.
I discovered that if I made the wrong choice, the version of me in the incorrect option would be mercilessly tortured by my yandere girlfriend, locked away in a dark room forever until she had drained me dry.
So...
I had no choice but to return to reality and try to reform her.
Waaah...
