Lee Jin-woo, Lee Tae-seung and Lee Woo-jin will release their mini-album "VERY, ON TOP" on various music sites on Sept. 18 at 6 p.m. under the name "TEEN TEEN."

"VERY, ON TOP" is TEEN TEEN's album that gives off fresh emotion and bright energy. It contains TEEN TEEN's honest and bold challenge to move toward higher ground as it cited " VERY, on Top," an English expression meaning "adds the best in the last."

The album consists of "On Top," an intro song with poetic lyrics on top of a sophisticated beat, the title song "Take Responsibility," which expresses the boys' courage to love, the song "Be My Girl," a sensuous confession song for lovers, and the song "With Me," which portrays the heart that has grown more affectionately while missing someone.

Lee Jin-woo, Lee Tae-seung and Lee Woo-jin, who are sixteen and a half years old on average, captured viewers with their young fresh image when they appeared on Mnet's survival program "Produce X101," which ended in July. The three members, who have been continuously loved since then, have formed a unit group for fans who have been looking forward to their debut.

Unit group name TEEN TEEN starts from TEEN, which means teenagers, and pop music TEEN POP, which means "teenagers who play pop music with teenage tastes."

Meanwhile, TEEN TEEN will release its mini album "VERY, ON TOP" on Sept. 18 and hold a showcase to mark the album's release at 7 p.m. on the same day.
