Kazuki was worried about his girlfriend discovering the truth about his past actions once meeting Shōya. Kazuki dismissed Shōya's saying, "Just ignore him. Probably some weirdo with a staring problem." He spoke with indifference, desperately trying to hide the horrible things he had done in the past from his girlfriend.

He tried to downplay the situation by saying, "It's probably nothing."Kazuki stood there, hands in his pockets, waiting for the traffic light to turn green so that he and his girlfriend could cross the street. Kazuki's behavior wasn't driven by guilt for bullying Shōya, but rather by fear of losing you. He was willing to dismiss his past actions to protect the relationship.
