Hey girl, I'm here from your comment on black swan, imma spoil the story for you, first of all, I've stopped reading it after last few chaps bcz, it was getting to toxic for me but, no, they didn't have any character development, jk starts banging lea while being in a rls, and he takes lea to the shopping to buy mercedes bday gift instead of mercedes herself and ends up buying gifts, especially lingeries for lea:(a little charater development is noticed that is jungkook somehow leaves mercedes bcz of his brother or something bad happened, and, marries lea, and later he surrenders himself to the police if I'm not wrong(i might be mixing other stories aswell, for that you can check the comments on the last chap) and they both get divorced after sometime, jk is in jail, and lea gets along with another nice guy, but again she has jk tattoos on herself whom she refuse to remove( idr if it was tattos or some jewelry but this shows that she really haven't moved on from jk and maybe aint totally loyal to the new guy) and she signs herself in some agency for music or dancing( i might be wrong, bcz ive been reading to many stories lately, also i stopped reading it after the chaps where jungkook is cheating on mercedes through lea, also at the same time he told everyone that him and lea aren't a thing, quavo dies ig,) maybe I've spoilt too much fy, but you can ofc continue reading it or if not, you can check comments on the last chaps like I've done. Not stopping you from loving the story or offend anyone, but i was disappointed to see that there wasn't that much of character development so that's it :)
