Gakko ja Oshierarenai! (2008)

Though quite different, as Gakko ja Oshierarenai! handles with various problems Tumbling does to but quite different ones. They feel very alike as both tell the story of teenagers of whom people have low expectations or who are outsiders try their best is their club activities and eventually prove that hard work pays off. Both are typical Japanese "Gambarou!" series.

Both shows are about a male student who has feelings for his male best friend and has trouble confessing to him. Gakko ja Oshierarenai is very focused on straight couples yet has a satisfying conclusion to the confession plot before the final episodes and a kiss.
