The music video teaser for Jeon So mi's debut song and title track "Birthday," which turns into a solo artist, has been released for the first time.

On June 12, the agency's The Black label released a teaser video for the music video of Jeon So-mi's debut single title track "BIRTHDAY" through their official SNS account.

In the video, which is as colorful and colorful as expected, Jeon So mi focuses her attention on her image as a cute girl who enjoys birthday parties and uses various costumes.

As much as flashy videos, the pop-up music sound of "Birthday" comes as impressive as it is enough to foretell a hit song at once.

"Birthday" is the work of hit-maker Teddy and a song co-composed by Jeon So mi, which is expected even more in that it marks the beginning of Jeon So mi's solo debut as well as the synergy effect that will be created by Jwon So mi and Teddy in the future.

Jeon So mi's title track "Birthday" and Jeon So mi's participation in songwriting and composing the title ‘Outta My Head’, just one day before her solo debut, was unveiled in a surprise move at 6 p.m. on June 12.
