I'm not too sad about missing stories from my lists. If they're there that's great, if they're gone, it's fine. I'll eventually remember the best ones.
I'm most upset about the fact that my notes for all the stories I read/am currently reading are gone. I usually reviewed everything I read. Hopefully, the devs can recover them but I have no hope. I guess I have to go back to the old fashioned way of keeping a separate reading journal.
Imo, this is the weakest story in the LIAI universe. Mainly because Byul is pretty much the same person from beginning to end. There could have been potential growth and self reflection from some of the plot points, like quitting the idol industry or secretly meeting his grandma who was a huge source of pain for his mom or being in an alpha x alpha relationship but it was all hurriedly glossed over and/or resolved quickly. Maybe Fargo should have picked one issue and fleshed it out instead of cramming everything into 60 short chapters.
