To his dismay, his maternal grandfather has died but no one in the family, including his mother (Crystal LEE), is willing to talk about it or their feelings.

The family of four will soon move to a new place, but a shadow of estrangement looms above them. Getting drenched in sweat, sometimes by rain, Cheng discovers a melancholy reality, both old and new, in a city he calls home.
