History3: Trap and Advance Bravely have a very similar vibe. Trap is pretty much the gay version of Advance Bravely.
The Girl From Nowhere series contains a certain feel and vibe that is present within some of the episodes of On Children. This vibe being a more dark and psychological look on society, using different elements to metaphorically display a person's hidden evil self. It is also similar as in both shows, each episode is set in a different setting.
They are both scripted variety shows. Both are scripted to set up a scene, than the rest is up to the cast.
Both dramas display the same type of humour. While Diary of Tootsies shows gay people. The Boy Next Door is technically not a gay drama. But does portray gay-ish themes.
