I’ve read more wonki but it’s always a side ship and not a main ship but if you’re okay with that here’s a nice wonki fic:

I’d also recommend following afteryoonie on ao3 (their twt @ is After_Yoonie) if you’re a big wonki enthusiast because I personally call them the president of that ship

I’d love to read any ni-ki suggestions you have so please drop them! (although I have to warn you I’m not a big fan of ni-ki x hyung line)
