Bolbbalgan4 and Henry covered Justin Bieber's hit song "Love Yourself".
The duo and Henry were the featured guests on the latest episode of JTBC's 'Idol Room', and they got together for a mini collaboration with Henry on violin and vocals, Woo Ji Yoon on the acoustic guitar, and Ahn Ji Young on vocals.
Henry also revealed he's a fan of Bolbbalgan4, saying, "I always liked Bolbbalgan4, and I still like them now. I really like their music, including their song 'Galaxy'. Whenever I'm with friends, they always ask me to sing that. I really wanted to meet you," and Ahn Ji Young responded, "He's so good at music and singing. We wanted to meet him too."
When Henry asked Woo Ji Yoon what her favorite guitar chord was, they both agreed the E chord was the best. MC Jung Hyung Don then pushed her to ask him if he has a girlfriend, and Henry responded, "Why are you curious about that?"
