I'm always like, what the hell happened last week? Then I have to read over what happened last week to even begin reading what's happening this week. With stuff like Mx0, I usually don't since it's pretty memorable. With stuff like Hatsukoi Limited, I may have to, but it doesn't really matter since each chapter is a different story focusing on a certain group of characters at a time. With stuff like To-Love-Ru, I don't even know anymore. I've forgotten a ton of the plot and each chapter might either be a pure comedy or a plot advancing. Hell, I can't even remember the characters anymore. At least that leaves me slightly fresh for the anime in April.
