There is not much confirmed information about Jimin's past love story. Most of what circulates are just rumors. In the world of K - pop, idols' personal lives, especially their love lives, are often the subject of speculation. It's important to take such stories with a grain of salt until there is official confirmation.
Well, there are some so - called 'insider' stories that pop up from time to time about Jimin's past love. However, these are usually not reliable. BTS as a whole has been extremely busy over the years. Jimin has been constantly working on his dancing, singing, and stage presence. It's very possible that his focus has been mainly on his career and not on romantic relationships. There's no solid evidence to suggest any significant past love story at this point.
Once upon a time, Reader was at a BTS concert. Jimin noticed Reader in the crowd and their eyes met. After the concert, by some lucky chance, Reader found Jimin outside the venue. They started talking, and there was an instant connection. Jimin was charmed by Reader's smile and Reader was in awe of Jimin's kindness. They exchanged numbers and from that day on, their love story began to unfold as they got to know each other better through texts and secret meet - ups.
Well, not much is known publicly about Jimin's love story. He's been very focused on his career in BTS. He has shown great love for his fans, which could be considered a kind of love story in the sense of the deep connection he has with them.
It's most likely just a rumor. There's no solid evidence to prove that they are in a love relationship. They are both popular in the K - pop industry, and fans might be shipping them together, but that doesn't mean there's an actual love story.
Another theme is the struggle with fame. In these fanfics, Jimin's stardom can be a hindrance to the relationship. The couple has to deal with the lack of privacy, media attention, and the jealousy of other fans. For example, in many stories, they have to find ways to have private dates without being caught by the paparazzi.
The rumor probably started from fans' fantasies. Since both Jimin and Rose are very popular and attractive, fans might have just imagined them as a couple and then the rumor spread.
There isn't a lot of publicly disclosed detailed 'first love story' in a very specific sense for Jimin. But he has mentioned in some interviews about his feelings towards love in general. He seems to value deep emotional connections. Maybe his first love, like for many people, was a pure and innocent feeling during his youth, perhaps a crush on someone in school, but this is just speculation.
Maybe Reader is an artist and Jimin discovers Reader's work. He is so impressed that he wants to collaborate. As they work together on a project, they start to see the beauty in each other not just in art but as people. Late - night studio sessions turn into deep conversations and shared secrets. They find themselves falling for each other as their creative energies merge.
It's mostly a fan - made concept. While Jungkook and Jimin are very close friends within BTS, there's no evidence to suggest a romantic love story. They share a deep bond of friendship which is often misinterpreted by some fans as something more romantic.
