An editor’s job is to condense long footage and make it not only entertaining, but also suitable to the target audience. For BTS (both domestic and foreign audiences), Bighit has decided to censor the staff’s faces, curse words, smoking, etc. That being said…
a) Of course there were missing parts, but the truth of the matter is that these Bangtan Bombs are glorified highlight reels. Nothing that I’ve seen in that video implicates an intentional attempt by the company to either edit out or hide something. Without seeing the entire footage, there is simply no way to say one thing or the other with clear certainty.
b) Yes, there have been incorrect subs from official sources. It’s nothing malicious however; I honestly think it’s human error. And there are always background conversations that are difficult to sub - that’s why they’re often left unsubbed (or maybe they thought it’s not important to the conversation so they didn’t bother to do it).
Are you saying that Jimin got those presents for JK as a graduation gift? Because if so, this is the first time I’m hearing this and I haven’t seen any other Korean fans mentioning it either… and we’re usually on top of our shit.
Finally, I just want to remind you and everybody else of this: When I translate background conversations or bring up things that international fans may have missed, I’m not suggesting that these were intentionally hidden or not supposed to be found out by the fans. As a shipper, I’m just sharing stuff that I and other Korean fans may have found interesting. That’s it. Ultimately, how you interpret that information is up to you, but I hope people do so within reasonable limits.
