We've seen a lot of stuff about KPOP Demon Hunters from a non-straight, trans, and disabled perspective, but we also wanted to point out the intersex reading you could have on it.
Rumi and Celine could be an extremely interesting representation on what it's like growing up visibly intersex. In this reading, Rumi represents a visibly intersex person, Celine represents the caregivers and doctors of a visibly intersex person, and the Honmoon represents the pericisnormative patriarchy.
Rumi was born with patterns. From the very start, Celine told her to hide them, to be ashamed of them, that they are wrong. She prevented her from coming out to her friends about her patterns. There's nothing wrong with Rumi's patterns, there never has been - the only reason why they hurt her is because of her own shame.
Celine imposes the role of a demon hunter onto her. She ignores her demon parts unless she can use it to further impose the idea of sealing the Honmoon (like how a visibly intersex child has their traits ignored unless it can be used to promote the patriarchy.)
Rumi tries so hard to hide her patterns, but slowly, they are spreading. Picture this like an intersex person hitting puberty or otherwise becoming more visibly intersex, struggling to hide their intersexuality with each passing day.
Rumi trying so hard to hide her patterns makes them more visible, and has negative side effects for her health (her voice.) This rings familiar to intersex people who are given/feel pressured to use "treatments" in order to "cure" their intersexuality, "treatments" that often have a negative effect on their body (ie; being forced onto hormones or birth control.)
When she is outed to her friends, and it goes over poorly, she goes to confront Celine. Celine can't even look at her body, saying lines like "everything I was taught told me you were wrong." She says that they can lie to hide her patterns again, that they can still "fix her." Rumi asks her why she can't even look at her, why she never loved her, and when Celine says she does love her and "tried to accept her", Rumi rightfully points out that her idea of "acceptance" is built upon only accepting her if she fits the specific roles imposed upon her and her body.
The movie ends with Rumi still having her patterns, happily showing them off, going to the bathhouse with her friends like she always was too ashamed to do before, and creating a new Honmoon that isn't built upon shame.
Anyways. Intersex Rumi headcanon anyone? /lh
