One can not keep everything as they are. Our life is too long to settle in one thing. Even with your strong feelings and determination, you can not help but say your wish and goodbye. The state of bittersweet.
Hope- to wait something(preferably good) to happen
well this story is about the cycle of life where life gives her happiness and again becomes cruel followed by a heartwarming bittersweet ending....wait till the end to cry :(
