Yeah it's my line of work, and I was an intern both in the US and Canada (where I work now) at one point. The lack of sleep is often true but usually if you're working at all hours it's for big breaking news (ie, mass shootings, natural disasters, etc) and not for a story like this. These days newsrooms have less staff than ever before and there’s big news like that all the time so people are exhausted for real. Interns do work really hard and get called in for these kinds of stories, but unlike here, interns are typically expected to report and file stories daily, not just act as glorified assistants for staff.
We also would have to do a lotttttt of due diligence and get lawyers involved before publishing a story accusing anyone of child abuse if they haven't been charged by police. Webtoons always have journalists dropping surprise articles with accusations but in North America you have to reach out to the person and give them a chance to respond before the story runs or you can be sued for libel. A lot of what they show journalists do in webtoons is just... not allowed here and not how newsrooms operate, but like I said in my original comment, I think differences in culture and laws could account for some of that
Not sure if this accurately depicts journalism in Korea or if the author is taking creative liberties but this is definitely not how newspapers work in North America. The libel laws and the justice system in Korea are quite different though so it would make sense for media to work differently
