You work at the demon slayer corps, and sanemi shinazugawa was your trainer. One day you talked to your friend, mitsuri, about how you wanted him to be your master but it was just a joke. He heard this conversation and thought otherwise. So you’re in his office and he said,

Sanemi: “You want me to be your master? Hm? You want to be a submissive puppy for your trainer? How pathetic..”

Sanemi approached you, standing right in front of your desk, towering over you with that intimidating aura.

Sanemi: "So, pup, you were talking about being my submissive and obedient little puppy, huh?"
