1. The trip happened in 2015, she's an early '97 so that makes her 20
2. Neverland (G-idle's fandom) never said that she was quiet and gentle. They praised her for being a gag character
3. YG didn't restrict male and female idols' interactions because of Miyeon. It was in place before that
4. Miyeon took a qualification exam
5. The reason why she left YG was because her debut was unlikely so she left by herself. She went on the trip afterwards
6. At that time, she didn't join any company, she wasn't a trainee either. She was a student at a vocal academy, that's it
