Comparison at a glance.
First we had China making an animated series based off several popular series in Japan, and now we might just have Taiwan doing the same thing, except it’s used for a variety show called “Wo Ai Hei Se Bang Bang Tang“.
According to the chinese bloggers and forums users that had accused the variety program of plagiarism, the opening sequence of the show had taken the BGM from K-ON! while the animation sequence was taken directly from Sayonara Zetsubo Sensei.
Nico Nico has also a video to highlight the comparisons between the original animes, as well as the supposed plagiarized opening sequence for the variety show. You can check it out at this link. Do note that you’ll need to have a Nico Nico account in order to view the video.
However, in the event that you don’t have one, a YouTube video is also available, but it includes all the other unnecessary details of the variety show in it. What you should pay attention is to the opening sequence of the video and you’ll more or less see what’s the similarities to K-ON! and Sayonara Zetsubo Sensei.
