Someone else in the comments below described this as "perfectly targeted at the self-flagellation that (white) folks tend to do online", and I have to fully agree. To preface, I am not East-Asian, but being a Black queer girl who has been constantly "othered" in White queer spaces, I could relate to what this Visual Novel was saying.
The fetishization of the racial "Other" by people who presume that because you both share the identity of being "queer" that no further introspection on their own beliefs and values have to be done, is unfortunately a common story among every queer person of color that I have known or spoken to in general. I wish it wasn't. The reveal of the churchgoers dying their hair to look "oriental" was a really good touch. I love that you chose to name the girl "The Outsider", because that is exactly what is feels like. You are an outsider to these spaces. Even if those spaces are meant to be "inclusive", as Mary also tried to tell The Outsider about the Church.
I don't have anything further insightful to say about this that hasn't been said below already in that very good analysis by A_Y_BING. This was very well-written and I resonated with it deeply. Thank you for sharing your work.
