My Sister, My Writer. It was a real struggle to finish it. Gross story, really unsettling, and felt uncomfortable the whole time. But I did finish it. :/
Not hate but does losing interest count?
Bleach over 600 chapters... But couldn't go though last 30-40 chapters or something like that... Just read the last chapter. Same for OP. At first I stopped reading it regularly and realized I did not care what happened in last chapter I missed... I haven't checked it in months.
TV series... I drop them a lot faster... I may simply check out the ending at YT or wiki if I ever get curious what was the ending.
