This show tries to be a hybrid of Saekano and Oregairu but it fails to deliver in an uncountable many ways. The one thing it truly delivers is a comedy, so it could be enjoyable if you like this specific type of humor and watch it just for laughs.
With every episode (AFAIK also with every LN volume) the story and characters gets more and more complicated and absurdly stupid.
My canonical version-that-explains-everything: the Cursed Bench-kun is an ultimate trickster playing evil jokes on mortals, transferring MC consciousness to an alternative gradually more unhinged universes every time MC dares to sit on him.

But at the same time, both have some of the most straightforward and "reliving" moments that totally caught you off guard (instead of dragging it out in most anime). Both have hidden actors with unknown motive, bad guy turned out to be good, and vice-versa.
Overall both can be a very low quality, but can be extremely fun watch.
