Modern time (Uppermoons x Male reader)

"I think y/n-sama is HIS reincarnation!"
"Don't be stupid no one can take HIS place"
"I'm starting to believe that he is HIS reincarnation"
"Y'all can stop talking about that now"

Y/n , an young adult who lost every bit of sanity in his life. Now he is gonna loose everything in his life after the 'Upper moons' have show up. Now he needs to teach them about the modern world, which is not an easy job. Although he is on the verge of sanity his job pays him well so he'll just have to bear it for now. Y/n knows nothing about Japanese culture, but he still grew up in an Asian household so he knows the basics of being an Asian parent to the Upper moons.
