Among all her brother's there was one was not at all common to her like others. He was someone whom she trust the most, who was her life , her world, her happiness and everything. He was Karan. She was not open to her parents. She never had courage to talk about her classmate boys in front of her parents. But Karan case was different. She was ready to face anything for him . She told her parents that he is her brother and she can do anything for him. And to her surprise her parents didn't even question her about him. They had trust on Karan. Karan was also in class 11th but he had maths as his subject and Sonal had biology. But they had common subject as physics chemistry and computer. They went 2 tuition classes after school that were common. Sonal's tuition schedule was set as biology from 4:30-5:30, physics from 6-7 and chemistry from 7:30-8:30. It was 9pm when she was going to come home. Karan also had same chemistry and physics tuition. For a girl to return at 9pm in India was not acceptable, but her parents did understand her and asked her to talk to Karan and he will drop her daily as her home was in the same way from where he had to go to his home.
