Thunder says his own solo agency has been running at a surplus.

On the February 12 airing of MBC Every1's 'Video Star,' the '91 line including Thunder, Mir, EXID's LE, DinDin, and Jinwoon joined as the guests.

Thunder, who established his own agency after leaving Mystic Entertainment, explained, "I went solo because there's music I want to pursue. In the past, you needed a lot of promotions, but now, people share it on social media if they really like the music and content. Every month, I've been releasing the music I want and having concerts and oversea fanmeetings."

When asked about his earnings, "Thunder said, "I started last September and it's been running at a surplus until December."

The MCs asked if Dara helped him out in establishing the agency. Thunder replied, "Noona is always giving me help. She's my investor."
