For the past five years, Lin has been looking after the son (Yo-yu) and the elderly mother (Mrs. Chou) of his deceased boyfriend (Li-wei). They live together like a family, and it is Lin's way of remembering Li-wei: by continuing to be in the life he once had and loving the people he once loved. But when Mrs. Chou passes away, her other son (Li-gang) returns from overseas and discovers that Mrs. Chou's property has been passed down to Yo-yu, whom Lin has legally adopted. Li-gang contacts the police, accusing Lin of killing his mother for attempting to own the property. As the ensuing investigation continues, more and more evidence mounts against Lin.
A boy lives with his Grandma and Mr. Lin, the tenant who looks after him and Grandma. But when Grandma passes away, the boy's uncle returns to Taiwan and discovers that ownership of the apartment was transferred to other people.
