People are allowed to criticise and will continue to criticise the manhwa they read. If you don’t like reading the criticism then don’t read the comments.
They are allowed to but it's stupid? Reading something they don't like? But maybe secretly they do and they can't cope so they have to say something to clarify they don't like it and delude themselves that their on some moral ethical shit
The only people outwardly claiming they don’t like this manhwa follow up by saying they’re dropping it so they obviously aren’t reading. Also most comments are clearly commenting on characters actions rather than the entire manhwa. Also people are excited for the 2 other side couples so they’d keep reading for them to show up. Not everyone feels the need to virtue signal it’s an anonymous site.
If you don’t like it, stop reading it, it’s not that hard you know ╮(￣▽￣)╭
