Because he enrolled in an international school and lived abroad for years, Jaeyun is fluent in English. He even watched Inside Out, the Disney movie, in English and had no problem with it.

Before Jaeyun officially moved back to Korea, when he was in middle school, he watched School 2013. It is a Korean drama about the hard work of students in high school, along with the problems around them. Because of that, Jaeyun was scared of the schools in Korea. Then he started taking Jiu-Jitsu classes. This made him good at Jiu-Jitsu and even ranked first in a competition that he joined.

When Jaeyun was in middle school, he met Beomgyu from TXT and other schoolmates. Jaeyun and Beomgyu were attending the same middle school in Daegu and formed a band. Beomgyu was the guitarist of the band, while Jaeyun was the vocalist. There’s a video of them performing.

Jaeyun started to set his goal clear. He wanted to be a singer, but he also had a backup plan too, which was to be a hotelier. However, he first had to take an audition. And to prepare for that, he applied for performing arts when he was about to enroll in high school. He was accepted into Hanlim Multi Arts High School. However, Jaeyun’s parents were against it. So, Jaeyun had to delay his dream and attended a high school in Daegu.

But he didn’t give up easily. Jaeyun went to a dance club when he was in high school, so he could learn to dance and sing better. So, when he was ready to join an audition next time, he could prepare for the best.

After that, Jaeyun joined an audition for a K-pop agency called Maroo Entertainment. It’s the agency overseeing Park Jihoon, Bonusbaby, Ghost9, etc. Jaeyun passed the audition and became a trainee there.

TO1’s Jaeyun in World Klass

Even though Jaeyun was a trainee of Maroo Entertainment, it would seem that his path to be an idol didn’t belong there. Jaeyun left the company and joined a survival show titled World Klass, which aired on Mnet. There were 20 global trainees that later on competed against each other to be part of the 10-member boy group called TO1.

Just like the title, World Klass, the show had a concept in which the participants were from various countries. The show was also filmed in several countries. Lil Pump the rapper was at one point a judge in one of the episodes too. During the show, the participants were told to team up and show their best performance.

Just like some other survival shows from Mnet, World Klass was a survival show based on voting from juries. Since Mnet had an issue with manipulating votes in their previous shows, they assured the fans that World Klass is not rigged. So, the top 10 final ranks will be debuting as TO1 after the show ends.

Let’s see Jaeyun’s performances in World Klass!

Even though Jaeyun showed his best, he only managed to rank 11th, making him unable to join the line-up of TO1. Jaeyun probably was sad at that time, but seems like it was his fate to join TO1 no matter what. One of the participants who ranked 3rd, Hanjun, was eliminated due to some scandals. A few days after the final line-up was revealed, Jaeyun was chosen to replace Hanjun, since he was the participant with the most votes beside the other 10.

Woah, it’s really good for Jaeyun since that means he’s able to debut as an idol. He finally can reach his dream. Good job, Jaeyun!
