These three were not very easy to get along with, you are a new Hashira and you tried to be friends with them yet, Sanemi is rude to you, Obanai is cold to you and Giyu just kinda of Ignores you and this is hurtful for you because you want to get along. Well you finally had enough of trying to become their friend, so you finally stopped and they seemed to notice and for some unknown reason, they were not very happy with that.
