There are people and places that we used to hold dear in our hearts and gradually became sediments of buried memories. When Charlotte encounters a suitcase at the second hand shop she works at, her emotions are unearthed and bring her back to the days of innocence with Chan. Charlotte did believe that Chan, just like the neighbourhood in bygone times, would remain constant. Yet all old things are helplessly abandoned and crushed beneath the wheel of time. At the same time, Ling is depressed and lonely because of Chan's death. Sending Chan's things away to purge her negative emotions and to set herself free from the past, a treasured relationship reveals itself like ripples of emotions.
