I saw this site a few days ago trying to look for places to share the info I have. sadly I can't disclose every detail for the sake of the idols. Keep in mind my english isnt that good so there may be bad grammar here. you dont have to believe me if you dont want to by the way. but here is some info I got while gossiping with other staff.
A popular idol couple broke up because the guy asked out a female idol from big 3 despite having a gf.
A member of a popular 3rd gen boy group likes to flirt with female staff, he never crosses the line though.
Groups from smaller companies are closer compared to big 3.
Two popular members of a popular gg had beef, they are kind of okay now.
A famous gg is not as close as they show, they had conflicts especially after their latest comeback. Their leader is desperately trying to hold everyone together.
There are groups who are genuine, not everyone is showing a fake personality.
Member of a famous bg known for his variety skills is currently the most popular among male idols.
A member of BTS asked out a female idol from a popular group but she rejected because she has a bf.
Two popular members from popular groups are dating, both are the fotg. Male and female.
Two male idols from 4gen are dating, they have given hints but people didn't notice.
A member of very popular 4th gen bg lost weight unhealthy because of insecurity.
A big 3 gg is not feeling safe in the company, as in privacy.
Gfriend disbandment is for the best. They beared a lot in source music.
That's all the info I know. Its fine if you dont believe me.. But there is more to the industry that meets the eye. if anyone has questions, just ask.

As I said, welcome!
