We mentioned that ONF debuted with 7 members who are Hyojin, E-Tion, J-Us, Wyatt, MK, Laun, and U. However, Laun had to depart from the group in 2019, leaving the group with only 6 members.

Laun was the maknae of the group. He was born in 1999 and went to the Seoul of Performing Arts High School. He was in the same class as the maknae of Oh My Girl, Arin, who came from WM Entertainment too. Laun was also the main dancer and sub-vocalist of the group.

However, on August 23rd, 2019, WM Entertainment announced the departure of Laun. They revealed that Laun has terminated the contract with them. Even so, they didn’t reveal the further reason for Laun’s settlement. In fact, they only said that Laun’s departure from the group was due to personal reasons.

What made fans feel suspicious about this was ONF’s member did a V-live eating ramen hours before the announcement of Laun’s departure. It is normal for idols to do a V-live no matter what they do there, including eating ramen. But usually, when there is a member who is about to leave the group, the other members have to postpone their activities first. As for J-Us, it seems like he wasn’t aware of Laun’s departure.

What do you think about this issue? Do you think that Laun’s departure was actually due to “personal reasons”? You can share your opinion in the comment section!
