Mostly 10 chapters long (main story). Some not done yet though. Mixed bag but I don't think there's a lot of angst there.
Oh. Note of warning. A lot have nonsensical plot. Brave them if you will
Also you gotta skim the list coz it's a mix of manhwa and mangas
Sorry for bombarding you but if manga is really what you prefer, maybe check these out? Majority of them are mangas and a lot of them, if not most of them, are already completed.
