BTOB's Minhyuk brought up his 'heyday' during the group's debut period when he was apparently more popular than Sungjae, particularly among older female idols.�

On the November 11 edition of 'Radio Star', MC Kyuhyun had remarked at him, "After your appearance on 'Idol Star Athletics Championship (ISAC),' we heard that you were approached by a lot of girl group members?" Minhyuk replied, "It's not because of ISAC, but after our debut, older girl group members just told me that we should maintain a friendly relationship..."�

Upon hearing this, Kim Gu Ra asked what may be a slightly sensitive question. He said, "Were you more popular than Sungjae at the time?" However, Minhyuk answered without hesitation, "Yes," drawing laughter. �The idol explained, "I was more popular than Sungjae [during our debut period]. At the time, Sungjae was in high school."�
