LUN8's JUNWOO Releases 'User Manual' for His Birthday… From MBTI Changes to Anonymous Member Reviews

LUN8 member JUNWOO met with fans through a 'User Manual V.26' video summarizing his characteristics to celebrate his birthday on September 21, 2026. In the released video, JUNWOO explained his personality, habits, and recent changes in detail, divided into 10 items.

"MBTI changed from ESTJ to ENFJ"... 10 Core Functions revealed by JUNWOO

At the beginning of the video, JUNWOO introduced his profile and mentioned a change in his personality type (MBTI). He stated that he was previously an ESTJ, but recently he has been hearing from those around him that he seems to have changed to an ENFJ. He explained that this is due to his habit of practicing and contemplating "what if" questions frequently, and that his tendency toward the F (Feeling) type has emerged recently as his way of speaking has become more empathetic.

JUNWOO presented three core functions that define him. The first is energy, meaning the 'infinite stamina' required for stage activities; the second is a 'melting smile' that receives feedback like "it feels like watching a youth drama"; and the third is 'consideration' based on his mother's teachings. In particular, he emphasized his character of valuing politeness, adding that these three are essential for a singer.

Additionally, JUNWOO cited Chinese language learning as a recently added function, and the habit of wearing a hat pulled down because he disliked looking in the mirror during his high school years as a disappeared function. He shared the change of now having the habit of looking in the mirror for choreography practice, stating, "Growth is possible only when you face things rather than avoid them." Meanwhile, he also shared human aspects, such as moments when his brain momentarily stops due to an 'error' or mistakes like taking the subway in the opposite direction.

Anonymous reviews from members, "A cool person who pursues perfection and a cutie"

JUNWOO then had time to guess the true feelings of his members by checking anonymous reviews written by the LUN8 members. The members left messages in different styles.

According to the subtitles in the video and JUNWOO's confirmation, the person who left the message 'Let's apply sunscreen' was revealed to be Kim Nam-gil. The author of the review who used the term 'pectoralis major' and described JUNWOO as 'a cool person who pursues perfection and a cutie' was Park Jin-su. Furthermore, the person who introduced themselves as a 'complete opposite mate' and mentioned having a different MBTI and tastes from JUNWOO was confirmed to be TAKUMA.

JUNWOO inferred the personalities of the members as he read their messages one by one. In particular, he showed intimacy with the members while checking the messages from Kairi, who left 'Let me use the computer,' and Yuma, who left 'Let's eat.' After finishing the reviews, JUNWOO expressed his feelings, saying, "It was fun to find out what the members think of me."

"Quickly recharged by compliments"... Gratitude toward fans

Finally, JUNWOO shared his methods and tips for recharging himself. He said his relaxation style has changed from his past way of relieving stress by playing games with the air conditioner on on rainy days to his recent way of going on trips to find nature. He also revealed that he gains the energy to perform even harder on stage when fans compliment him by saying, "You are truly cool."

JUNWOO expressed his affection for the fans, saying, "Without LUV8, this birthday would have been meaningless as well." He concluded the video with a determination to continue being a singer who shows great performances in the future.
