Given how much credence "the power of love" gets in media, Izuku being completely unmoved by it is pretty amusing. Especially since the power of love is something that exists in universe, Gentle and La Brava's love is genuine, and Izuku's motives in this fight are far more opaque that Gentle's here.
Izuku's lack of understanding of romantic love in this scene in conjunction with that scene with Toga and Izuku in Act Three unintentionally gives him some aromantic coding.
It's clearly unintentional. Horikoshi was going for Izuku never considering romance because he always thought of himself as a loser and had no self-worth. But Izuku lacks the resentment of couples/women or the romantic self-pitying tendencies that go hand in hand with those kinds of guys. And when approached with the idea of romantic love in Act Three, he could only name shoujo manga tropes and compare Toga's feelings to a nonromantic type of love.
