Yah, I found my Sanrio-loving fanfic-writing trans bf during Calculus tutoring. Flipside of the same coin. You gotta find the places where the shitposters would congregate. Arcades, boardgame clubs, libraries, gardening clubs, anywhere where Shojo manga is sold, volunteering maybe. You really have to fight to find one in person, but they exist. Wherever being "Autistic is a compliment", my bf says being autistic themselves.
Revised Hepburn would say it is rendered shōjo, omitting the U but adding a long mark. But a lot of times we also omit the long marks, such as with the city of Tokyo. Wapuro (word processor) style would write it as shoujo, because that is how you would type it using a standard Latin alphabet keyboard.
