Before the controversy happened, the entire Kpop community was discussing Red Velvet's future and many people believed Irene was done with the Kpop life. She doesn't seem very invested compared to the other members and probably wanted to pursue acting. Before the controversy, Reveluvs would have been upset but still supported her and she'd still have a successful career.
But then the scandal happened and people questioned her character. If Irene were to leave now, people wouldn't be supportive, they'd think she's a massive diva, especially if she is the only member who did not re-sign. So in order to keep her career alive, she stuck with the team a little longer.
What do you think of that?
