Stretched after chapter 500

#1

Good book to read, translation is sometimes off but holds attention for such a long story line because of well defined characters. only after chapter 500 or so, suddenly the character development isn’t great. Just to stretch the story the basic premise of this romance - transparency is questioned. suddenly the lead lady character starts hiding another man’s advances towards her. It really gets annoying as it seems to be done only to increase no. of chapters.
