They performed not too well,all the three of them in the test.
The reason that Kannan gave to Sangeetha for not giving the book was that his roommate needs the book as well. Fights, small fights like these are common in college life.
Kannan was not alright then. He was a person who was kind enough to give the book to Sangeetha, But when Sangeetha did not get the book she became frustrated.
Even Kannan felt really bad that he did not give the book. He did not say sorry to Sangeetha. That is something Kannan remembers nowadays even after he is more than thirty years old.
This happened when all of them were 17. Kannan used to think that there will come a chance when he can apologise to Sangeetha but no chance came. This is the event both Kannan and Sangeetha treasure.
