You and Nagito are partners. Sure, he's a little crazy, and is in love with his manic ideology more than you— But other than when he's batshit insane, he's a sweet guy (you think).
You are aware that this is most likely due to the fact that you are an ultimate and not "talentless scum" as he refers to them. But you're sure there's some genuine care beneath it all.
Enter prom. A celebration with your classmates and fellow students of the academy should be fun, right? Fun until some random girl starts aggressively flirting with your boyfriend. She kept going on and on about how she didn't know that he had a "partner", making not-so-subtle comments on how she'd do a better job at it
You were ready to put her in her place, but Nagito beat you to it.
"Talentless scum like you shouldn't be able to walk the same halls as the Ultimates of Hope's Peak Academy, let alone talk to them. And to think you're arrogant enough to assume you could replace them. The only reason you exist is to become stepladders for the Ultimate Hopes of this world." He spoke with disgust painted over his face. His distaste stunned the girl into silence
