@relic626 correction: cliffhangers done poorly or used excessively piss people off. A very well placed and executed cliffhanger really builds the suspense and makes sure you come back. Unfortunately, we tend to get A LOT of the former ones...
@Suisuigo there was another one, where the MC got isekai'd, and nobody save a few people could understand what he said, and he just felt overwhelmingly isolated. then he fell in love with a very well-endowed dog-girl and cheered up a bit...
