RM is famously known as the leader of BTS. But when he was a student, he was mostly known for his intelligence. In fact, the “Persona” rapper was ranked in the top 1.3 percent of students in South Korea on his freshman high school exams.

With an IQ of 148, RM is practically a genius. However, despite this fact, the BTS star revealed that he wasn’t happy as a student.

But RM’s unhappiness didn’t have to do with his performance in school. The BTS leader revealed in a past interview that he wasn’t happy around that time because he didn’t have a “clear goal.”

“Until the first grade of high school, I didn’t have a clear goal, and as a hobby, I used to rap… I just studied because I thought, even if I find a dream, I wouldn’t be able to achieve my dream if my grades are bad. So honestly, I wasn’t happy while I was studying,” he said.

But RM then shared that once he came out to the real world, he was thankful that he studied hard. He said that he encountered many moments where he had to be smart, and the things that he learned in school came in handy.

But RM is not only academically intelligent as he’s also very smart when it comes to music, the entertainment industry, and a lot more. With this kind of intelligence, many are probably very curious as to how the BTS star’s brain works. Surprisingly, fans can now feed this curiosity through the contents of his wallet.

RM once revealed the contents of his wallet so an expert would evaluate what kind of brain he had, left or right-sided. Despite his genius status, the BTS star is clumsy and loses things quite often. With that said, RM showed an empty wallet during the interview, explaining that he lost his original wallet and had to buy a new one.

Since he didn’t have enough time to put all his stuff inside the new wallet, RM only had two cards inside. The BTS leader even lost his identification card.

After seeing the contents of his wallet, RM was informed that he was right-sided, based on the way he organized the items inside. Shockingly, despite his wallet being bare, the result fits the 26-year-old rapper, songwriter, and record producer perfectly.

“Right-brained people, on the other hand, exceed in creativity, colors, music, drawing — those kinds of arts. Music and physical education,” the expert said.
