As the family members of some of the biggest stars in the entertainment industry, BTS’s siblings naturally can’t avoid becoming subjects of public curiosity and attention. ARMYs are well aware that the BTS members all have brothers and sisters, yet there isn’t much information or many photos of them, since most of them do not work in the entertainment industry — with the exception of j-hope’s older sister, a well-known KOL (key opinion leader) and social media influencer.

On the other hand, over the years, the BTS members have been extremely careful about protecting their family members’ privacy, as they understand all too well the dark side of fame. As a result, they rarely mention their siblings or share photos of them. Rarely — but not never! Fortunately, there are still moments when they feel safe enough to tell fans stories about their siblings or post a few family photos.

RM is considered one of the most open members in this regard. Last November, he even shared, for the first time ever, a series of clear portrait photos of the Kim family. RM and his father wore identical suits, perfectly embodying the image of reliable pillars of the family, while his mother and younger sister looked radiant and beautiful, clearly reflecting their place as the most beloved women in the household.

In particular, fans paid close attention to RM’s younger sister, Kim Kyung Min. Many commented that Kyung Min looked sweet and innocent, with facial features that strongly resembled her older brother’s. She is the same age as Jungkook, born in 1997, and she currently runs a café called “Cafe Far Ben” in central Seoul. On the café’s opening day, Jimin’s father and RM’s father reportedly sent congratulatory flower wreaths, while j-hope’s sister even visited in person to show her support.

Because the age gap between them is not very large, RM once shared that he and Kyung Min used to argue and compete constantly when they were young, just like any other siblings. He even once “got back at” her by taking every umbrella in the house on a rainy day, leaving her without one when she went out to play.

But of course, as they grew older, their sibling relationship became so warm that fans couldn’t help but admire it. One unforgettable memory for ARMYs regarding the Kim siblings was when the K-pop star proudly shared Kyung Min’s academic achievement on Twitter — the moment she found out she had scored the highest in English on an exam.

She immediately texted her brother, who was working far from home: "Lulu lulu~~~ I got first tier for English!!!! I’m oppa’s sister that you can be proud of. You can brag about me now." RM was surprised and kept praising her hard work. He replied, "Oh, yah, how did that happen? I’m proud of you. It was worth calling you yesterday. Guess you’re pretty for the first time in a while?". Kyung Min then thanked him for the compliments.

And just as Kyung Min had said, her brother was so proud that he immediately shared the news with millions of fans around the world. What was funny was that RM soon had to delete the post, along with a short explanation: "I will erase it, just in case, for my sister’s image. All the test takers, you’ve worked hard. It’s cold out so be sure to dress warm."

Although it was only an ordinary conversation between the two siblings, RM’s reaction — and the way he quickly shared his sister’s achievement with fans on social media — was more than enough to show just how much he loves and cares for her. Many fans admitted they felt jealous of Kyung Min for having a world-famous older brother who is so gentle and thoughtful. Some even gave RM the nickname “the nation’s eldest brother”!

As a celebrity, it is understandable that RM has many concerns about sharing his family with the public. However, looking at the journey — from sharing the siblings’ text messages and quickly deleting them, to posting family photos taken from behind or with half their faces covered during past trips, and now finally revealing clear family portraits — it is evident how much more trust he has gradually placed in ARMYs.

At the same time, thinking about those moments when RM couldn’t hold back and wanted to share the Kim family’s happiness with the fandom makes fans deeply emotional. These moments allow fans to gain a deeper understanding of his personality and everyday relationships. They also serve as a reminder that fans must respect artists’ privacy. The restraint shown by fans today is precisely what will allow RM — and more broadly, BTS — to feel more comfortable sharing personal joys in the future.
