Meet Mi-young Choi! My K-Pop Demon Hunters OC.
She's mostly demon but she's also part human like Rumi but Mi-young is more like a 1/4th-1/8th human than half and half. She's albino and generally very sweet, almost submissive, in public but she's a lot more relaxed in private. She's a little entitled though because although she's not his actual child, she considers gwi-ma to be her dad in a way (and he feeds the delusion in order to control her) and considers herself a princess as a result.
She, like how the Saja boys each represent a bad piece of the kpop scene, she also represents some of the darker sides of the female k pop scene due to her trying to fulfill the mysognistic expectations of a woman in general, but especially in Asia, and it's resulted in her performing regardless of how detrimental it is to her (her albinism causes some pretty severe light sensitivity in the eyes so the bright lights of the stage are slowly blinding her), she often lets male idols and fans walk all over her sweet demeanor and she's got anorexia.
As for the happier side, I ship her with Mira and have the headcanons that Mira is a closeted lesbian/bisexual and she hides it from her parents and fans but Rumi and Zoey know so when Mira can't hide her crush, they tease her about it. Mira discovering she's a demon was a trip but they help each other by Mi-young helping Mira come to terms with being sapphic and open about it (because she is) and Mira helping her come out of her people-pleasing nature because she sees herself in her (due to Mi-young trying to fit into the unnatural expectations of a woman in a high class family and Mira having had that struggle)
Here's her winter clothing
Here's her performance outfit too
I'll be posting a few other pieces in the coming days with Mi-young in them 😚
