I laughed hard when Ritsu just when "oh shit, Yui finally died."
I think it honestly made K-On more enjoyable.
is this the one where mugi takes a shit on the beach?
Nope this is the one where terrible thing happen to everyone except ritsu who knows she's mediocre from the start and Mugi who just becomes a trophy wife and does lots of drugs.
I loved the end
Than is it the one where yui OD's and has serious sister problems? Its hard to keep track of these.
