Article] SS501's Kim Hyung Jun, Heo Young Saeng - K-pop Idols with Blood Type O]

The best thing is that SS501 is still MENTIONED before their names  ^^

Totally true about our IDOLS

People with blood type O are usually ambitious, confident, kind, extroverted, a leader, and honest. They make friends wherever they go and are amiable, gregarious, and fun to be around. They enjoy dipping their toes into lots of different things but find they get bored quite easily. Because of their various interests and their ability to get bored, they can make colossal mistakes due to their haphazardly characteristics. They also straddle the arrogant/vain line because of their strong personalities.

In terms of male idols, U-KISS's Kevin and Eli are blood type O, SS501's Hyung Jun and Young Saeng, JYJ's Jaejoong and Yoochun, Super Junior's Kangin, Shindong, Eunhyuk, and Ryeowook, SHINee's Onew, 2PM's Nichkhun, Infinite's Myungsoo, Shinhwa's Dongwon and Andy, B2ST's Junhyung, CNBLUE's Jonghyun and FTISLAND's Seunghyun.

In regards to female idols with blood type O, 2NE1's Minzy, SNSD Taeyeon's fellow group members Sooyoung and Tiffany fall into the blood type O category, along with f(x)'s Sulli, Brown Eyed Girls's Jea, Secret's Jieun, Davichi's Minkyung, Miss A's Jia, Wonder Girls' Yubin and Lim, T-ara's Hyomin, Eunjung, and Hwayoung.
