The BTS Universe or Bangtan Universe (often shortened to BU) was initially know as "The Most Beautiful Moment in Life series", "Hwa Yang Yeon Hwa series" or "HYYH series" until the official name and logo were first used in 2017, is a South Korean media franchise and shared fictional universe that is centered on a series of music videos and short films, independently produced by Big Hit Entertainment and based on characters inspired by the members of BTS. The franchise has expanded to include short stories, books and a webtoon. In the future is planned to release a drama and a game of the franchise.
On April 29, 2015, BTS began their second era with a mini album and "I Need U" serving as the album's title track. The music video for this track shows a story of the seven members in an alternate reality, depicting their anxieties and uncertainties as they confront their futures. Following this music video, multiple pieces of content were released in this era and in their third era. Due to the popularity of the fictional universe, Big Hit Entertainment named it the "BU", or "BTS Universe".
On June 29, 2017, the BTS Wings Concept Book, the first piece of BU content with the official BTS Universe logo, was released. In an interview from July 2017, RM explains the origin of their "I Need U" and "Run" music videos by saying: "Stars Wars came out tens of years ago, but a dad and his son still go to a theater to see it. It’s not just like a five-year or a ten-year thing, you know what I mean? Our company knew that and they always told us about how important it is to make a universe similar to the Star Wars Universe or the Marvel Cinematic Universe." In August 2017, at the start of their fourth era, posters of the fictional characters were released. At the same time, the phrase "BU content certified by Big Hit Entertainment" was added to all music videos and short films that were part of the BU.
"Seven boys. Best friends. Their fates intertwined through the good times together, but also the tough times, as they have gone their separate ways and suffered greatly as a result. When all is almost lost for these boys, one is given a special chance to go back in time and help his friends fix the mistakes that led them down this path. He’ll do anything to save them, but can he? Or is he too late?" – Plot summary of the 花樣年華 Pt.0 <SAVE ME> webtoon.

On August 9, 2017, Jin posted on Twitter a selca featuring a bouquet of flowers and the word "Smeraldo", which is not an actual flower. However, the fans found Testesso, a fictional florist who is planning on opening a shop called "Smeraldo Flower Shop".
Testesso has a Naver Blog about the Smeraldo Flower and his shop, with different stories about the origin of the flower and his experiences with it. These stories were deleted and the BU logo was added to the blog on July 4, 2018. A few days later, the blog started to post the same stories as last year, but the eighth story changed and Seok-jin didn't pre-order the Smeraldo Flowers for the girl because he turned back the time.
Also, the Instagram account associated with the blog was deleted and re-opened on July 20, 2018, with content alike to previously uploaded and the Twitter account was private since August 2017, until the content was deleted and reupdated on July 2018.
As of July 6, 2020, all the content of the blog was deleted for the second time with posts slowly being reuploaded again on the same dates. However, the third story changes and gets uploaded on July 15, 2020 instead of July 17, 2020. In the previous versions, Testesso talks about how the flower was first discovered in real life. On the 2020 version, he talks about seeing a man with an umbrella stopping in front of the shop during the typhoon.
*Don't confuse Jin, the vocalist of BTS with Seok-jin, the fictional character.

The sheet caught fire and instantly flared up. My last sight of this world was this dirty, isolated room, the red-hot flames and rolling heat, and JungKook's twisted face. – Yoon-gi, 2 May Year 22.
My narcolepsy occurred anytime, anywhere. I always ended up having dreams about Mom when I blacked out. The dreams were all alike. I was heading somewhere with Mom on a bus. – Ho-seok, 10 May Year 22.
Several days ago, l'd been here and seen some graffit. I'd automatically looked around, but TaeHyung had been nowhere in sight. I stared at the graffiti painted all over the wall for a while. – Nam-joon, 13 July Year 22.
