"I feel, I had enough here. Many dreams have been achieved." = I can't see I'll get interesting job offers from outside. There is nothing new left for me to do. "If there is a chance to join JKT48 Operational Team (JOT), I will support JKT48 from behind." = Incomes of me and staffers aren't much different/ not any better. You won't want to quit being a singer to be a staffer if your income is significantly higher. You need not to quit being the front girl to help the behind the scene team. Some AKB's members have done so.
