I rememeber when BB was the undisputed GOAT in mid 2016 and BTS suddenly blew up by the end of the year.
Eh, I'm pretty sure they didn't suddenly blew up. It's a gradual climb since debut (more noticably since 2015), esp with I Need U (in Korea) and when Dope went semi viral on Youtube for international audience.
What was that like to witness? I wasn't here until early 2017.
Speaking as a fan, 2015-2016 was really ugly in term of fanwars imo, esp 2015 (nothing can top those years for me). Seriously, so many useless BS happened throughout the year. So many plagiarism accusation thrown at BTS, sajaengi accusation (to the point where Bighit went to the court to prove their innocence), RM+BTS got mocked and laughed at by the entire Kpop community when he said he wants to win ONE Daesang in his entire career, the old narrative "BTS need a hit song to be called a Top Group", etc. Oh, I also remember the petition to the Blue House, when BTS won their first Daesang bcs some ppl thought it's very undeserved, man thats so absurd. Sorry for chiming in lol.
