Okay so are polylight and Rumi’s dad all in a relationship together, or is it just him and Miyeong and Miyeong with polylight?
Either way, I love them so much🥹
Lets see I have like 3 versions of them not all have ever been posted or drawn out(yet?) but there's the Everyone lives AU, Everyone but Celine lives AU, and the Semi-Canon AU(Everyone is gone and Celine and Rumi are alone until Huntrix). In all the AUs above the relationship is as follows Celine, Poppy(3rd), and Mi-yeong are in a relationship. Mi-yeong, Poppy, and Suho(Dad) are in a relationship. Celine and Suho are not together in the same way they are with Poppy and Mi-yeong they have an affectionate Bromance thing going on. Polylight pre-existed Suho joining but they had only been together for like a year or two.
Don't get it twisted the relationship as a whole was not a one and done deal that'd be too easy.
Celine and Suho's relationship Specifically was built on the gradual building of trust and their childhoods sort of mirroring each other in a way(Celine didn't want to be a hunter and Suho never asked to be a demon). And their mutual devotion to Poppy and Mi-yeong and later on Rumi.
Poppy and Suho's relationship was more lax in its progression than Celine and his but it stemmed from Mi-yeong's relationship with him and the weird similarities to Celine he has (*Celine and Suho unintentionally doing the exact same dumbass thing and it worked out because the duo are charming AF* "Oh god?! Fuck! No!"- Poppy's thoughts as she watches them while sweating bullets after being hit with the metaphorical 'Your in love with these dumbasses' brick™)
Mi-yeong's relationship with him was probably the quickest and easiest. After Suho started living with them(long story) and filling out and looking less starved it became very apparent how similar he and Celine looked her thoughts went wild from there and then it became a matter of getting Celine and Poppy to agree somehow(little did she know she wouldn't have to work very hard to get Poppy to cave)
*Celine and Suho fighting in the grass about something*
Mi-yeong and very quickly Poppy:
Hope that makes sense😅
P.s. Only in the Semi-canon AU do Huntrix not know about Polylight+Suho being a thing until after the events of the movie because in that AU Celine kept that shit under lock and key close to her heart because it hurt more to fathom the idea of the public knowing and twisting that love in anyway than to just never tell anyone. Bobby was the only one who knew but he was a working idol himself and a friend of theirs at the time Polylight+Suho were together and saw real time the devastation of losing them caused for Celine. But in quiet moments where no one else could see or hear or hurt her Celine could talk about them with Bobby. What a wonderfully bittersweet day it was for Bobby to see when Celine started to share them with Rumi, Mira, and Zoey as well.
