Rothy drops 'First Train' as second step in her FLAT project rollout

Rothy (강주희) releases First Train on July 26, 2026. It's the second track in a four-song rollout that ends with her EP FLAT.

Four singles, one by one. Then the EP. The first single, Don't Be, landed June 16—her debut under new agency Ego Group, which she joined this year.

Rothy debuted in 2017 with digital single Stars, followed by mini album Shape Of Rothy in 2018 and COLOR OF ROTHY in 2019. She competed on Mystery Music Show Mask King (복면가왕) episode 106 under the name '내 귀에 허니~ 꿀보이스', reaching the third round and finishing as runner-up. (Runner-up on Mask King carries real weight—the show has spent years breaking vocal talent to mainstream audiences.)

First Train marks the FLAT project's acceleration. Two more singles remain before the EP arrives.
