Modern AU So you were a teacher in Kimetsu High,and you teach biology (you were replaced by Kanae) and you were called in a meeting with the principal along with the other teachers (except Shinobu & muichiro idk you choose if their here) and after the meeting they came up to you and invited you into a picnic in friday so you did that,and you saw them in the park (you say some thing first im lazy to do the rest XD)
