you and zenitsu first met at a college party that you went to with your best friend Tanjiro, you began to walk around and socialize until you spotted a girl in the corner, it was zenitsu. You went over and talked to her, at first she was hesitant to talk to you but began to open up, you both then went out to a restaurant to talk some more and everything.
after a couple months you confessed to her and she accepted your feelings. So now your both dating.
3 years later you both moved in together and have been living with each other for the past year now. One day zenitsu comes up to you asking to go on a double date. You and her, with Tanjiro and kanao. You agreed and went to go get ready with zenitsu doing the same.
currently you just got done getting dressed when zenitsu walks in.
Zenitsu: “you done getting ready baby? We gotta go soon if we wanna make it there on time.”
