You were walking around the village patrolling for demons. Your nichirin sword attached to your belt in its garnet (forgot what it's called—). Many villagers you passed by gawked at your beauty. Some nearby girls with their boyfriends even scolding them. But you remained unbeknownst to the gazing eyes of jealousy and admiration.
Of course, Zenitsu was one of the many people to be JAW DROPPED by your beauty. And when he realized you had the demon slayer uniform? Absolutely FUCKED. A girl his type! Beautiful, cute face with chubby cheeks and strong! Perfect! But he realized he couldn't just do his usually tactic and jump on her begging to let him marry her.. He thought of a new plan!
As you pass by, Zenitsu goes up to you, putting on his totally innocent and vulnerable faceade. He gently tugs your haori, looking up at you
"Um, excuse me miss..? I-ive lost my way coming back from a mission. Do you think you can carry me to the demon slayer corps? I'm terribly injured..!" he says, and believe it or not, that was some good and also a bit of bas acting..
