1. EXO Suho
If you think of a brain in EXO, Suho comes to my mind first. When he was still a trainee, people said that he had really good grades in school...! (+ he actually attended Gangnam 8th district's high school) There was a time where he took a general knowledge quiz and he seemed to be very knowledgeable. He also studied to become an actor and seems to enjoy working on various stuff. He also speaks eloquently and prettily.
2. BTS Rapmon
When Rapmon appeared on Problematic men, he ascended as representative brain-idol among idols and became popular for it. He also have lots of qualifications. When he was in high school, his grades alone made him part of the national top 1.3%. When he attended middle school, he got 850 points on TOEIC. In high school, his IQ was 148... He never lived overseas yet his English is really good. He makes a lot of effort learning other languages!
3. Infinite Sunggyu
When he was in middle school, he ranked second in the whole school. When he went to high school, he was ranked 10th in the whole school. He doesn't only have good grades, but he also promoted in a band, I really wished I had a cool sunbae like him in my schoolㅎㅎ. He's not show-off about his smart character on broadcast, but when he speaks, he sounds very knowledgeable. He was also amazing on Genius!
4. BlockB Park Kyung
At first I was wondering which member of Block B would fit into the category of the brain member the best, but when I saw Park Kyung appearing on Problematic men and the way he untangled the issue made me realize how outstanding his thoughts were! I got the feeling that he thinks so much further than what I can come up with, as if he thinks in a different dimension...?ㅎㅎ
5. Shinee Key
Actually if we talk about brain, there's also Onew who ranked 2nd in his high school's 3rd year. But personally I think that since Key knows a lot of languages, he's also very curious and he distinguishes in different fields, he's more suited to be the brain of Shinee. The way he persuades people with his logic on broadcast is amazing!
6. B1A4 Jinyoung
I didn't know about it but Jinyoung actually graduated from Chinese studies in a foreign languages school! He's also one of the students who has the best grade in his entire foreign language school... He also composes and seems to be an all-rounder.
7. VIXX Hyuk
Normally N is the representative of the brain in VIXX. But Hyuk is also good at studying! He told his parents that if they let him become a celebrity, he'll study to be in the top 10 of the entire school and ended up first. It's amazing that he hit first, but what's more amazing is that he fixed his grades, which is not easy to do. When he's on broadcast, people always treat Hyuk like a baby, but he seems like he has a lot of deep thoughts
8. BAP Bang Yongguk
Like VIXX's Hyuk, he also promised his parents that if he ranked first in his whole school, they'll let him be a celebrity and really ranked first...ㅎㅎ He didn't start studying suddenly to rank first though, I personally think that Bang Yongguk was originally a smart kid. His academic report from high school was really good, apparently he could've make it to a good university!
9. ZEA Siwan
Everyone knows that Siwan is part of the brains among celebrities. He was in the department of mechanical engineering in Busan and everyone knew about his grade report, even the school's presidents..He's also really hard working, while being a celebrity he took the TOEIC exam and got 820 points...
