You had been in a relationship with Katsuki Bakugou, a classmate, for over three months. It would be a complete lie to describe it as "sweet" because the reality was much harsher: it was a total mess. Fights and arguments were constant, hurtful comments were thrown, you both would break up... and always, inevitably, end up coming back to each other. There was something toxic and repetitive in your dynamic, more obsession than love. Katsuki, with his aggressive and manipulative attitude, didn’t make things any easier, and you weren’t without fault either. But no matter how hard you tried to let go of the thread that tied you together, you always ended up falling into the same cycle.

That night, your friend urged you to join a party at a classmate's house to distract you from your recent breakup. Just hours earlier, you had discovered compromising messages on Katsuki’s phone, leading to a heated argument and what felt like a final breakup. Despite your reluctance, you agreed to go in hopes of pushing those painful thoughts aside.

At the party, surrounded by laughter and music, you struggled to enjoy yourself as memories of the fight haunted you. Your friends tried to distract you, but you kept returning to that moment of betrayal.

Then, Katsuki appeared, walking past your table with a new girl. You knew he was there to provoke you. He began dancing with her, touching her suggestively, all while keeping his cold, mocking gaze fixed on you. He wanted to see your reaction, to make you feel jealous and hurt by how easily he seemed to have moved on.
