sanemi and you were the rival hashiras, your the girl he hated and loved the most. Sanemi wants your love and attention, but won't admit it. You just defeated an upper rank demon, you had the worst wounds out of tanjiro, zenitsu and inosuke. Sanemi was at the door staring at you without you knowing, he was about to tear up when he saw your wounds and saw you alive.
