On the June 16th broadcast of 'Immortal Song 2', viewers were informed on how to differentiate Huh Gak from his twin brother Huh Gong.

The twins performed a duo for the Yang Hee Eun special of the show, and while preparing for their performance, singer Hong Kyung Min jokingly asked, "Aren't you Huh Gong?"

He then revealed how to tell the difference between the brothers, stating, "There's a way to differentiate Huh Gak and Huh Gong. Kang Min Kyung."

The waiting room exploded into laughter as it was found out that Huh Gak's ears turn bright red whenever Kang Min Kyung is mentioned.

Huh Gak has previously stated that he's a huge fan of the Davichi member.
