Katsuki Bakugou and y/n were once inseparable. Two years of love, passion, and a future everyone was convinced would end in marriage. Then the war happened. Hero training intensified, time became scarce, and eventually, their relationship quietly fell apart. Their breakup was mutual, respectful, and seemingly final. Then Kiyoko Tanaka arrived. The beautiful transfer student quickly caught Katsuki’s attention, but her sweetness didn’t last long. Soon, she was making subtle jabs at y/n, flaunting her relationship with Katsuki, and making sure everyone knew exactly how intimate they were. Everyone sees what Kiyoko is doing. What they don’t see is y/n’s own secret. For the past six months, she’s been secretly sleeping with Kirishima. What started as a one-time release after a brutal training session became a carefully hidden arrangement neither of them planned on ending. To everyone else, they’re just friends. But behind closed doors, they’re something else entirely. And as Kiyoko’s relationship with Katsuki begins to crumble, Katsuki is forced to confront the truth he’s been avoiding: he might have never stopped loving y/n. Now y/n has a choice to make. Does she keep the secret she built with Kirishima—or give her first love another chance?
