Sensei Overnight

If you were to spend so much of your life doing one thing in one place, to move to a different place to do the same thing, would that be considered a 'fresh start'? In Sensei Overnight, Janu (or whatever you change his name to) gets this question answered for him, as he goes from a nonchalant janitor to a sensei in, well, overnight. He has questions, and nobody is giving him clear answers, so what else is there to do than explore this new lifestyle he's been gifted, along with his new students. - (All characters are 18+ unless stated otherwise).​
