Facing challenges solo: 'It was no walk in the park'

Yeonjun's first solo project tested his mettle.

"Honestly speaking, I thought I was ready for this, but then I realized after working on it, that it was no walk in the park," he shares.

"It was really difficult. It was very challenging to do the vocals, the rap and the dance all at once. I tried doing everything at the same time. It's very tiring. So while working on the choreo and the song, I came to really respect solo artists," Yeonjun adds.

But Yeonjun's experiences with a group helped him along the way. "I think only because I am part of Tomorrow X Together – and I've been through so much together with them – that's why I could try this. I could take on this challenge," he says.

"If I weren't in the team, I don't think this would have been possible," Yeonjun adds.

"I did feel a lot of stress, a lot of pressure, sometimes to the point that it almost scared me. Whenever I was met with those emotions, the bandmates would come to me, they would give me a lot of words of encouragement and boost my self-confidence and self-assurance," he says. "Thanks to them, I could pull it off and finish this journey."
