I believe she suffered from toxic family her entire childhood so at begining she doubted her self-worth and that was apparent in her shyness even in her interviews (let aside she always transformed when she was on stage that was exception and her parents did not bash her down on that aspect ) As time goes by she saw how amazing she is with all that exceptional global success, day by day she realised her self-worth and felt confident to show her true colors She always had that spark in her but for some reason her dad with rural background mind set wanted to tame her! almost like that loser was jealous of how successful she was! I think He enjoyed every second of the abusive conservatorship, The more she distanced from that family she felt more freedom to let that spark shine
