Fatal Girlfriend: Please Abide by the Rules of Love

Traveling into a world of strange rules and stories, everyone else was desperately trying to survive, and I was the only one who was forcibly assigned a "perfect girlfriend." The love rules here are outrageous: [Rule 1: Your girlfriend loves you very much. If she stands on the bedside and stares at you in the middle of the night, please hug her immediately and say "I love you", otherwise she will eat your head out of sadness. [Rule 2: On a date, no matter what she hands you (even if it is red liquid), drink it with a smile. [Rule 3: Never try to break up! In this world, the price of breaking up is to be buried forever. Looking at my girlfriend who was pale in front of me and with bleeding eyes, I kissed her with tears in my eyes: "Baby, I will never leave you in this life!" As long as I don't break up, you can't kill me!
