So I suddenly remembered recently, about this one seulrene fic I read a while back. I think it was something that made a joke about thongs like 'There's somethong about her' but I'm not sure. I loved that fic but it didn't update frequently which is how I lost sight on it. It was really well written and the humour was great!  I think it was about Seulgi being a national geographic photographer and then she went on this expedition with Joy and Yeri and later on met Irene and Wendy. I t

in which a unexpected breakup occurs between Seulgi and Irene, and Seulgi contemplates before finally realising Irene was what she needed all along.

When Seulgi confesses to Irene, her crush of 2 years and is accepted, she's ecstatic.   But she doesn't know the real reason why Irene accepted and agreed to be her girlfriend...
