Wait, does that mean that nafra is still smelly??? She stinked a lot when they where on the harvest festival
well they spent quite some time together during the harvest festival so he may have taken note of the perfume she uses. I do it as well I meet like a random person today and if I meet them the next two days or so I would probably say to myself, ah so it's that person that smelt like that or wore that perfume yesterday
True plus shes also in the student council so they might hang around with each other when iruma was at the student council
Iruma know by smelling... (⊙…⊙ )
