On the episode of KBS2's talk show and music program "Yoo Hee Yeol's Sketchbook," the Zion T. appeared as a guest and noted the happenings on his life. He also talked about the events that occurred throughout his music career. 

Host Yoo Hee Yeol asked Zion.T what he considers to be the first chapter in his career, and the artist replied, "I think it would be when I launched my first track. I was not part of any agency at that time, but I had to make a release, that's why I contacted a distributor and randomly chose a date of when to reveal my single entitled Click Me."

Zion.T continued saying, "It was when I guested on 'Infinite Challenge' that my single called 'Yanghwa BRDG' began to be more renowned. I think it even returned to the charts about eight or nine months following its release."

The male idol also mentioned that after launching "Yanghwa BRDG," he began to know about mainstream music core. "As soon as I learned about it, I wanted to release more of my mellow music, so I did, including "No Makeup," "Eat," and "Just," which I accomplished with Crush. With those, I discovered that I could also sing gentler tracks."

Zion.T then later explained the title of his most recent single saying, "You may be wondering why I released this piece this month, but it is called "May." It's because three years ago, I was able to complete the first verse and chorus. It turned into an eerie collaborating between my present self and myself from the past."

He also graced the audience with his performance of "May" on "Yoo Hee Yeol's Sketchbook."

Zion.T started his music career in 2011, working with Korean hip hop artists including Dok2, Simon D, Gray, Crucial Star, and Primary. The first song he released was a collaboration with Dok2 entitled "Click Me." Two years later, Zion.T joined his first label Amoeba Culture and had his first studio album called "Red Light" launched. Also in 2013, he was featured in several tracks of idols such as Infinite H, G-Dragon, Dynamic Duo, and Swings.

Aside from issuing his own songs, Zion.T also participated in recording the original soundtrack titled "Kiss Me" for the television drama "Pinocchio." In 2016, he parted ways with his three-year company Amoeba Culture and signed an exclusive contract with The Black Label, one of the subsidiaries of YG Entertainment. He released his first extended play under The Black Label in February 2017, titled "OO."
