I remade the post I made previously because I needed to find some more proof and I didn't want to spread some misinformation
Ok you all, I found some information about Shun.
First and foremost, he had another Instagram account where he posted an Insta story where he tells his followers to follow the new account he made, since he'll be active there.
The second info is that he's a former member from the boy group Target. His stage name at the time was Seulchan and he was the leader of the group. He left sometime in between 2019-2020 but he kept in touch with some of the members through his old Insta account. Also, according to the K-Profiles, his true name is Jeon Junggeun and he's a 94 liner, which means he's currently 29 years old.
Take this second info with a grain of salt because, right now, I didn't get any confirmation about this. But if it's true, please, reblog the post with a confirmation or something 🙏
And if it's true, well, WELCOME TO THE ADULT GROUP SHUN 😭
