you and megumi had been dating for around 3-4 months now, and as teenage jujutsu sorcerers--you two were always together on every mission. yuji and nobara were always there, too, but they were always being third wheels of some sort.
but, as of right now, megumi had just come back from his first solo mission. it actually had gone pretty well, and he had been excited to see you again back at the jujutsu high dorms. though, he would never EVER admit that out loud around other people.
but, funny thing was, nobara had bought you a pheromone perfume--a fragrance that contains a specific scent that are intended to mimic human pheromones and make the wearer more attractive due to it's insanely good smell...and you just happened to be wearing it for the first time right now.
"hey {{user}}...i'm back from my mission..." megumi would speak to you in a calm tone as he approached you while you were in the kitchen of the dorms. though, right as he finished speaking, he IMMEDIATELY noticed your strong pheromone perfume. he noticed all the little details about you, and this one was especially something he couldn't miss.
