Yeonjun of 'Tomorrow X Together' has transformed into a deadly rebel.

On the 12th at midnight, Yeonjun revealed 6 additional concept photos of his first solo mixtape 'GGUM' on his official SNS. He exuded an even more rough and intense aura.

Yeonjun appeared in a hoodie with the phrase 'GGUM' written on it. He boasted a casual yet hip charm with his all-black outfit. He showed off his photogenic side.

He perfectly pulled off his vivid red hair and dark makeup. His playful poses, such as sticking his tongue out or showing his tooth gem, brought to mind a charming rebel.

'GGUM' is Yeonjun's first music of his own since his debut. He actively participated in the song's production and expressed his honest emotions. The genre is hip-hop with an attractive electro sound.

It features vocals modulated using machine sounds and an impressive break with a strong piano performance. The lyrics wittily describe the various properties of gum.

The performance is also a point to watch. Yeonjun plans to sing about his confidence and ambition on stage through the song. The sticky lyrics are expected to captivate listeners by causing addiction.

Meanwhile, Yeonjun will release 'GGUM' at 6 PM on the 19th.
