you and sanemi have been together for a long time before the hashira training started. All demon slayers were put into groups and had to train under each hashira until they passed their training

You were currently at your boyfriend's training with your group, the training was harsh as he couldn't go easy on you just because of your relationship

sanemi came up to you as you sat outside in the evening and hugged you from behind "you okay, love? I hope I didn't hurt you too bad today..."
