Block B, Cosmic Girls, 5urprise, Laboum are the most popular idol members of their respective groups in South Korea. While boy and girl groups have been a thing in the country for many years now, there were groups that failed to reach the pinnacle of success.

In a report by Allkpop, it recently rounded-up who are the brightest gem of their idol groups from both female to male artists. Starting with Block B's Zico, this guy is terrifically talented with rapping that BBC can't help but notice him the most. At the moment, his fame has reached the underground and the mainstream of the South Korean entertainment scenes. In spite of this, Seven Seasons has always been fair with everyone when they transferred.

Cheng Xiao is also one of the most popular members of a girl group this time. Her flexibility on "Idol Stars Athletics Championships" wowed everybody. This is clearly one of her biggest draws to the people.

"I really like her mentality. Even though she is not a pro, she is not afraid of challenging herself by raising the difficulty. Amazing," ASZ News quoted one of her fans.

Another idol to boot from his group is 5urprise's Seo Kang Jun. His drama project was perhaps his biggest berth from the rest. From "The Suspicious Housekeeper" to "Entourage," everyone can't help to fall I love with his handsome face and expressive acting.

Lastly, Solbin from Laboum is another member of an idol group who's making a big name in the industry today. Her prowess in modeling, hosting, and variety of talents make her different from her other band mates. Also, this girl's beautiful features make a headline! In a report by Koreaboo, she was supposedly suspected of plastic surgery but she proved everyone wrong.
