Unfortunately there was a major hiccup a couple of months ago. All list went to already read and all notes were gone. We had to go one by one with the list to srt it again and check where we left off. It was the only way the admins could protect and recover our lists. As I know. I had to go through over 200 pages of mylist to sort it again. I suggest you do the same with yours oneby one. ╮( ̄▽ ̄)╭
I also had mangas and others on my list that I clearly remember never marked, just read in some chapters and because I did not like it I never marked them, but they were clearly there when I started recovering my stuff. It was like they could only do the recovering by going back couple of years in our reading lists. Or something.
I came across this one while I was sorting my manhwas lol. I had left notes in the comments of the manhwas about whether I was letting them marinate, had dropped them, or what the story was about... and for the manhwas I’d already read, I left notes about how I felt about them (quite literally essays). NOW THEY'RE ALL GONE, SO I’M HELLA CLUELESS!! TT. I gotta reread every manhwa just to figure out whether I was even reading it TT.

For some reason this is in my "already read" list with 1 star rating. But it has no notes, which I usually leave when I give low ratings, to remind me exactly why I hated the story (got tired of clicking the same stories with changed covers).
