they're so good friends. Gyuri mentioned that when yoobin joined WG she sent her a msg about it.
And I think they also mentioned each other on their thanks on their album. That's really nice. They're still best friends and all after those years.
she's probably working up to the university entry this year to satisfy her father.
after that all we could do is to sign the petition to bring her back. like she said as long as people wants her to come back, she would!
