Over the past 10 years, fans have known that BTS members rarely share pictures of their siblings and they do a really good job of protecting their family's privacy. But as top stars in the entertainment industry, BTS's siblings cannot avoid becoming a topic of interest.

Therefore, on rare occasions, members may mention some information related to their siblings or share a memorable story about them. Especially RM, who couldn't hide his pride when talking about his sister's achievements with ARMYs, and that was the first time fans saw him unable to contain his joy to show off his little sister.

Even though they deleted it after considering some surrounding issues, ARMY still feels very admired for their wonderful brotherly love:

Most ARMYs know that in addition to the members, each BTS member also has their own brothers and sisters. Most of them do not work related to the entertainment industry, but they receive a lot of public attention because they are the families of the world's top superstars.

But of course, BTS always tries to carefully protect their identities to avoid negative effects on their loved ones. Therefore, there is very little information that we can know about their family or siblings. However, fortunately, in some cases, the members can be generous in telling a little interesting story about their brotherhood.

One of them is RM and interesting stories related to his only sister. RM's younger sister is the person whose identity he fiercely protected from the moment she debuted until she became the world's top artist. Almost no information or images about her have been revealed, but ARMY is sure that she also possesses a lovely, lovely beauty as some leaked photos since RM's debut.

RM's younger sister is named Kim Kyung Min, the same age as Jungkook when he was born in 1997. Because the age gap is not far apart, like any other pair of siblings, when they were teenagers, they both fought a lot. One time, RM even "revenged" his sister by taking all the umbrellas in the house on a rainy day so that his sister wouldn't have an umbrella while hanging out. 

But later, their brotherhood is soмєтнing that fans admire more than ever. In particular, it was shown through one time RM personally shared a conversation between him and his sister on Twitter because he couldn't hide his pride for her.

Specifically, that was when he received notice from his sister that she had achieved the highest score in English in an exam. When Kyung Min knew the results, she immediately sent a text message to her brother who was working far away because she wanted him to be proud of his sister for achieving such good results.

In the message, RM's sister wrote: "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."

Of course, RM was surprised by her achievements and continuously praised her hard work. He texted back: "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?" and Kyung Min thanked him afterwards.

And just like how Kyung Min wanted his brother to be proud, RM posted a chat and shared about his sister's good achievements. But the funny thing is that RM quickly deleted the chat messages after a while. In a tweet, he explained that he deleted it because he was concerned about how the negative comments might affect her.

He wrote: "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."

Even though RM only shared a few rare minutes about his sister, you can see how much love and pride he has for her. In the end, he always considered protecting her privacy but did not forget to express his joy because his sister worked hard and did well in an exam.

Perhaps, at this time, RM's sister has had a successful life and makes RM continue to be as proud of her as ever!
