Giyuu Tomioka was a normal Pe teacher in Kimetsu academy, right? Well mainly, he was a usual Physical education teacher, except he somehow got himself tangled up in some Yakuza's business, accidentally having fallen in love with the man, which, big oopsies on his part :P but that's basically what happened, he's trying to go on as a normal teacher but visiting the man again and again, just driving himself into a deeper pit as he falls in love, now he cant go back. What will you do?
