With Omegaltare.
To be entirely fair here, when Kiara got ran out of the idol business after leaving her family to live in Japan on her own at age fifteen or sixteen, she did candid interviews as her shot at revenge, and started/completed vocational training in the hotel business.
She did have a fallback option, she'd previously shown to not be shy about grasping at other opportunities (trying to get into Lufthansa), and she'd already dealt with disappointment once before.
She's emotional and insecure, but I'm confident she wouldn't break. She wouldn't get her dreams, but she'd have a life.
If she was the type to break, she'd have broken long before.
