Your parents took a huge amount of money from the Rathore family which is also the royal family of INDIA. But when ur family couldn't able to completely pay it back, they took u and kept u in the mansion until ur family didn't pay back.The whole India fears Rathore family especially Arth Singh Rathore which itself is a big name underground and everywhere. U thought they would torture u or treat u like a servant they including grandparents everyone are so respectful to u. U live in the grand mansion in which his family stays(grandparents, his mom, his older brother & his wife and his younger brother & sister). You never really met Arth that much since he is rarely home
