It is a story of a small boy called Oliver, who had a friend which no other companion of his rivalled to the extent that it shared his laughter, tears, and dreams. Yet with every passing year and every changing season, the old friends' memories of him would fade much more and he just became a fragment of the busy adult life.

The duo of Oliver and Lily depends on imagination and creativity shared. They have a world of amazing adventures in which ordinary moments are like extraordinary solutions. Oliver, an endless seeker of knowledge, and Lily, who has unbridled spirit, would find peace in one another's acceptance and cheer.

Due to his manner of speaking, one can say that Heidegger’s style is nonconformist, but very thoughtful. Through a silent language of signs and gestures, they go together in search of their imaginary worlds where they share stories and dreams that no one can understand but them. This unique tongue is going to be a common heritage where they can express themselves out without any fear and self-inhibition.

A girl, Lily, walked into a small shop one rainy afternoon. As the sunlight from the golden sky shone on the old boards, she crossed paths with a book. Inside of the title his fingers traced over her cruel cut hair, touching the ancient secrets of lost tales.

As Lily flips the pages, she comes across a story of sweet sour friendship stolen and rediscovered – of how these memories, voices of gone friends, keep on lingering longing to be revived again.

So when she slips the book back on the shelf, Lily hardly can ever forget the bond of friendship, the memories of these people as well as all that she has learned from her "forgotten friend".
