He left the group previously.
Former DAY6‘s Jae, now known as eaJ Park, recently left a comment on a TikTok that gained traction. The original creator of the video had gotten emotional, talking about the so-called “least popular” member in any K-Pop group. eaJ left a comment claiming that he greatly related to her scenario, admitting that he had been the one in that position when he was in the band.

I was that person in Korea. It was painful to attend fan-related events. During our second comeback, the producers told me not to give speeches. At every fan event, I somewhat felt like I didn’t belong there. It took some time to get used to it, but I eventually did. Of course, I received love from overseas, and even from a few Korean fans, and I will forever be grateful to those people. I still remember the short conversations we had over those years. So when you meet a group you like, show love to everyone.

Jae had claimed that attending fan events had been painful for him as such. He had previously even been told by producers to refrain from participating in public speeches the group had to give. He found comfort in the few that supported him, resulting in his gratitude. His takeaway was that whenever you meet a group, even if there is a member you do not particularly like, you should show love to all members.
Netizens did not agree with eaJ, not for what he had adviced, but because they felt that DAY6 did not have severe popularity disparities in the first place. They felt that since he had already left the group, he should not speak on them.

- DAY6 didn’t have severe popularity disparities, to the point where there was no unpopular member. Even if you had a bias, you’d be fans of everyone.
- No, but why does he keep running his mouth?
- He’s starting again.
- He’s at it again… If he just stayed still, he’d be lauded for his good vocal color. Why is he like that?
- Didn’t he leave before they got popular?
- Why is he like that?
eaJ was once an integral part of the group. As he had been on K-Pop Star before debuting, he had already amassed many fans. Later, he left the group after struggling with various controversies and health issues. You can read more about it below.
