Katsuki tried explaining that he never did it, Izuku was broken because he had a crush on Katsuki but after this he just couldn't be associated with Katsuki and made him his rival. After that Izuku stopped singing his soulmate song because he was taken aback by his mother's death and couldn't handle it.
