So the days of their 11th class started. By chance because of more students in maths batch some of them were shifted to biology batch as they had mostly same subjects as physics, chemistry and comp only difference was the main subject maths and biology so at that time students were adjusted. It was Karan's luck as he thought the same because he wanted to be in her class. Now they shared same class, same tuition, same way. Other than Karan there was one more person in Sonal's life. She was her best friend Riya. Sonal's life was just revolving around Karan and Riya. She loved them both but Riya was in the maths Batch and her class was not shiftef so Karan and Sonal were only feeling her absence but when they both were together it was difficult for both of them to concentrate on someone else , they were enough for each other. They three had the best trio in school. One the naughtiest but most caring and understanding : Karan, second was the pure soul, best personality: Riya and the last but not least a little mad but for both of them, and was life of Karan and Riya: Sonal . Everyone in the school was jealous of their bond. On one side everyone wanted Karan, every fourth girl in the school dream for a boy like Karan. But he was only Sonal's. They both were not only brother sister but best friends, parents for each other and everything.
