au where rumi isnt half demon, those are just honmoon markings because shes actually a polylight honmoon baby, but thirdlight/poppy (as ive been calling her) thinks miyeong cheated on her and celine with a demon and runs out on them, and her not being there means that celine and miyeong are more easily overwhelmed by demons which leads to miyeong dying in a demon attack
but poppy doesnt know thats how miyeong died because she’s not around, she just sees the public reason for miyeongs death and then assumes rumi killed her even though shes a baby. she considers going back to celine but “she chose her side”.
celine is left almost catatonic by the entire affair, but she knows that rumi is hers. she’s a lot more laid back in this au, a lot less concerned with rumi hiding her markings. she dotes on her, thats her precious baby girl. the last remnant of the two loves of her life. she calls her her “little bundle of starlight” which evolves into just “my starlight” when rumi gets older
cut to over 20 years later. rumi is way better adjusted, way less self conscious. polytrix is already together by the time their adults bc they’re all being open and honest about their feelings in this au. the three of them are super happy. celine is way more happy than she is in canon.
and then poppy comes back. because she figures its time to finally “right miyeongs wrongs”.
she tries to hunt rumi down, but is stopped at every turn by the honmoon “why are you protecting her?” she yells at it one day. “shes a monster! shes an abomination! shes-“
“shes yours.” a voice says behind her. poppy turns. its celine. “and mine. and mimis.”
“thats a lie.” poppy shakes her head. “that cant be true. its impossible.”
“its not a lie, and it is very possible” celine says. she would know. one side effect to the girls being a lot more open and…active much earlier is that one of them got pregnant young. they were still in training at the time, and they had no interactions with literally anyone outside of each other and celine so they knew there was no other way for it to have happened. they ended up getting an abortion, because they were way too young to be parents.
theyve been a bit more careful since then, but it confirmed to them the fact they can, in fact, use the honmoon to have kids.
celine explains this to poppy, who’s in shock. “youre not lying?”
celine doesnt speak at first, but poppy urges her on. “we were overwhelmed. there was nothing i couldve done to help her. or so my therapist will have me try to believe.”
“its my fault.” poppy sobs, “i shouldve been there”
“youre here now. and you have a lot of time to be making up.”
she takes her to officially meet rumi, who, of course, is with mira and zoey. mira gasps when she sees poppy and summons her weapon, “thats the bitch whos been trying to hunt down rumi!”
“im sorry.” poppy says “i was…i was working under a misconception.” she turns to face rumi. now that she really is looking at her, she sees parts of her that clearly come from herself. “i…i know the truth now. hi.”
“i never thought…how could i have known the honmoon would let us be able to…to have children together?”
before celine can answer her, polytrix all pale. “uh,” zoey says, sweating and poking her index fingers together, “about that…”
and thats how poppy finds out shes a mother and a soon to be grandmother all in one day
