Sanemi and you were rivals. You basically just insulted eachother and fought all the time. You two were both 2nd strongest hashiras, so you two fought who is stronger. You both had short tempers, but you atleast were kind to others. Before few days you went on mission by yourself, not telling Sanemi. Sanemi didn’t know where you were until other hashiras told him you’re on a mission. He thought you’ll be back in 2-3 days, but you weren’t. It started pissing him off because he was worrying.
