gugudan hogwarts AU where they’re members of the gobstones club. najeong-centric (mostly anyway...?)

very brief very general premise:
sejeong is a former ~superstar~ quidditch player who finds herself becoming a part of the gobstones club when she's invited to join them. they're supposedly nobodies to the rest of hogwarts (totally irrelevant!) but it's apparent the gobstones club is much more than what it seems. nayoung piques her interest, but really, they all seem a little sketchy? while sejeong usually has no problem meshing well with others, will she fit in with this ragtag group just fine?? what unresolved issues and secrets do they share amongst themselves that make them so ~mysterious~???

note: not a crack fic even if that description may suggest otherwise 

7th years - hana (gryffindor) & mimi (slytherin)
6th years - sejeong (gryffindor), nayoung (slytherin), haebin (hufflepuff), soyee (ravenclaw), sally (ravenclaw) 
5th years - mina (hufflepuff) & hyeyeon (slytherin)

this started off as a one-shot but then I got waaay too invested in it and now it's turned into a multi-chaptered fic oh boy enjoy!
