Imagine this: you have found a new series and the desciption sounded very nice. Then you began to read it and you loved it. You turn the page and ... see something that doesn't really please you.

So what would it be, that can make you drop a manga/manhwa/manhua? (but I mean things that aren't so predictable and that catch you off guard...)

I must say luckyly this hasn't happened to me that often. If I dropped a series I was mostly not so keen about it, anyway.
However, what really makes me annoyed in a manga is, when a character is supposed to sound cool and suddenly spouts some over-dramatic words... (you can find this in maaaaany shoujos 😐 )

There's nothing to see here. Proceed with what you were doing or throw rainbows at random pedestrians.

When it became ridiculously long for the same reason.

(e.g: Futari Ecchi)

Repeat.
What turns you off... about a manga.
Fickle Readers?

oh ... sorry 😔 haven't noticed that
