too much romance is given in the book which is a bad thing about book but nice thing is it teaches us how to handle the parents and ,how the couple specially the boy manages the parents from both side as well as not to loose hope .
Rest the ending is same in a classic chetan bhagat novel style where lover longs for her/his mate and other side refuses and soon the persons's health deteriorates , which leads to lover becoming concious and coming back to the other part,soon their love grows/blossoms again from autumn to spring
