But Yuk's hopes are dashed on finding his dad has a new family and considers him a burden. Alone and homeless, Yuk is taken in by Auntie Fen, a middle-aged recluse who leads a solitary existence. At first, their different habits and personalities lead to numerous squabbles, intensified by Yuk's self-centeredness and Fen's odd temperament. As time goes on, Yuk learns Fen is in the early stages of Alzheimer's. The discovery unexpectedly serves as a catalyst for the young man's growth as a caring friend. For the first time in her life, Fen feels truly blessed. But it is a situation rife with irony due to the nature of her disease and the accelerating elusiveness of feelings and memories.
