Two idol siblings have come together for an epic AKMU cover!

On February 6 KST, former Co-Ed School/SPEED idol Sungmin took to his YouTube variety channel SINGOSIK to release a performance video of him and his younger sister, IZ*ONE's Choi Ye Na, singing a cover of AKMU's 2021 single "NAKKA" featuring IU.

In the clip, the siblings go by the team name of 'Hakdong Musician,' a play on words that combines AKMU's name with their neighborhood in Seoul's Hakdong area. They also wear matching suits and sunglasses while they sing, showing not only their performance chemistry but similarly playful personalities.

Meanwhile, Sungmin is currently active as an actor while Choi Ye Na made her solo debut last month.
