I usually can read something with 60-50 chapters in half a day or so. My friends take longer. Usually I don't have anything to do after I come home from college and do my assignments, so I just read some and watch K-drama with my boyfriend.
If you're the talkin about novels then if the story really captures me, I can finish it within one day. If not, then I can finish it in 4 days. If you're talking about webtoons, then I can finish it in one day if it's totally completed. reply
Usually, when a webtoon/manga is so good i like to read it slowly to savour the moment so it takes me like a day to read 40-50 chapters but if it's just reading to waste time and i dont really care if it ends it'll take me a few hours to read 60 chapters reply
For a short manga, like 5 chapters it takes my like an hour. For a longer manga, like 50 chapters, it can take anywhere between 5 hours to 2 days. And for a really long manga, like 100 - 200 chapters, I can finish it in a week or so. I take so long 'cause I read slow and sometimes I got things to do. reply
It depends on what I'm reading because when I read Jinx and The third ending I really had to hold myself back from reading all of it/catch up, so I mean if it's REALLY good probably 2-3 hours but if it's not amazing but still pretty good probably a few days maybe a week reply
