You were a new hashira and you've seen other talk bad about giyu but you had a soft spot for him since you knew how he felt you stick up for Giyu and defend him and bc you talked back to shinobu now she despises you she would spread lies and rumors and when you were in a meeting she started to make fun of you and make you embarrassed by sharing personal things about you and your past as Giyu knows this happened bc of him and bc you sticked up for him
