Jimin, Jimin—JUST B’s leader Lim Jimin~
You said you’d only date after your contract ends~
How long are you going to keep showing off with your girlfriend, a female staff member?
You even made a full-on lovestagram—how long are you going to blatantly lie to fans!!— Post




The account also shared another clip, seeming to imply the person seen behind Lim Jimin in the clip is his alleged staff member girlfriend.
백스테이지. 남친 투샷 찍을때. 공연중.
팬 옆자리까지 항상 빠짐없이 챙기시던데
헤메 맞죠??
일보다 팬 구경이 더 중요해 보이셔서요 https://t.co/6j49f6P3JT pic.twitter.com/7aTMhp6eXU— h dk a bk f (@hdkabkf156820) January 4, 2026
Backstage. Taking couple shots with your boyfriend. During the show.
You always made sure to look after her, even down to the seats next to fans—without fail.
That’s hair and makeup staff, right??
It honestly looks like paying attention to fans matters more to you than doing your actual work.— Post
While the post did get some negative reactions, international netizens heavily defended the idol’s right to date, stating that it did not affect the 24-year-old doing his job.
Y’all are so weird for this. Being an idol is his job. He doesn’t owe you anything, he can do anything he wants,when he’s not working including dating. Why is that the end of the world? We’re in this their for music, not to get boyfriends? Stop being parasocial and let them live https://t.co/WMajK0YIr0
