Billy members Moon Sua and Si Yoon performed a congratulatory show at the '2025 KBO League' game between the Kiwoom Heroes and Doosan Bears held at Seoul's Gocheok Sky Dome on the 23rd.

The two members not only threw the first pitch and hit but also held a congratulatory performance during cleaning time, adding their unique powerful energy to invigorate the game that day.

Moon Sua said, “I’m very honored and thankful to share the first hit with Kiwoom. I wish all players participating in the game safety and hope they can showcase their skills beautifully with sincere support,” and Si Yoon noted, “I really wanted to throw the first pitch, and I’m delighted and excited to have this precious opportunity. Since it’s a special experience, I think I will remember it for a long time. I will wholeheartedly support to ensure it’s a great game.”
