Confused Character of Shivay?

But i m really confused. He seems arrogant and money-grubbing. These types of people only care about themselves. On the contrary, Shivay loves his family and is ready to make sacrifices for his brothers. He shows his rude behavior against Anika but with soumya he behaved v mannerly. She also belonged to middle class family as her mother is nurse. It really shocked me. He has variety of shades😊

I also want solid reason for his behavior

Might be his heart condition🤣

Doctor bola beta apne heart ko sakht kar lo tabhi tum jee sakte ho🤣 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

But, i also want a reasoning behind his behaviour hahaha
