You just hated someone cuz the man you like doted on her more and dedicated to working songs just for his sister. They're siblings which means they're family. Of course MC will prioritize his family since he couldn't do that before. For her to be insecure just cuz she's seeing how he's been doting on his sister screams insecurity. At least sister tried to grow more when she felt insecure towards her. But her? Totally opposite.
