Ryu Mi-yeong (류미영) and Cha Jin-shik (차진식):
Realized I did some for Rujinu and had to do for them, too. Also, as I headcanon Jinu as Choi Jinu, I just wanted Rumi's dad to have a last name with C and a first name with J, too, just for fun (Rumi really is her mother's daughter). Also chose it because it's super symetrical with Rumi's mom name (3 letters surname, 7 letters first name separated by an "-"). A few arrow references because according to a concept art I don't remember (please send me if you find it), Zoey has a picture of the Sunlight Sisters with Celine with a sword, Mi-yeong with a bow and the third member with a weapon I don't recall, so I'll suppose Mi-yeong was an archer, at least for now. Won't give away much more details because I plan on writing about them in the future, on ao3, so I won't spoil anything.
