@Kiyone-Chan volume 1 to 3 has major grammar errors unless he fixed it but it gets very good moving forward and currently the fanfic is at Volume 0 so it'll take a very long time for you to catch up so take your time reading peak lol.
is there any chance that you'll be doing a sequel to "He Will Be Mine"? its so good, and im actually near to tears when i scrolled through the last chapter only to be hit with "you have finished reading"
