On May 20, he was revealed as a contestant for SBS's audition show LOUD. During the tenth episode, which was aired on August 7, he received the casting offer from both P Nation and JYP Entertainment, but ended up accepting the casting offer from JYP Entertainment. In the final round he and the 4 members of Team JYP won the online vote, thus automatically being announced as part of the group.
He used to be a YG Japan trainee and trained with Treasure’s Japanese members. A clip of him dancing with the other YG Japan trainees was shown on YG Treasure Box.
His mom is a 2PM fan, his pictures as a child attending 2PM concerts in Japan were shown on Loud.
His TMI is that he freezes/forgets after walking 3 steps. It is a Japanese proverb pertaining to people who are forgetful since chickens forget after 3 steps. It also fits him since he was born in the year of the chicken.
