Mattheo Riddle and Y/N don’t know how to fight fair. Every disagreement becomes a competition. Who apologized last. Who sacrificed more. Who loved harder. Who hurt the other worse. What once started as playful bickering slowly turns into something neither of them can control. Every argument leaves another tally mark, every harsh word becomes ammunition for the next fight, and every “I’m sorry” feels less like an apology and more like admitting defeat. Their friends watch the cracks spread. They insist they’re fine. After all, they’re still together. But when one devastating argument forces every buried resentment into the open, Mattheo and Y/N are left with one impossible question: What happens when you finally win the fight… …and realize you’ve lost the person you were fighting for?
