Tong's father vomits blood in the bathroom toilet. Later, his wife discovers him and his blanket soiled in blood, because of liver failure.

Tong's father is depicted as an alcoholic and chronically consumes alcohol throughout the movie. In several scenes, teenagers consume alcohol in night-time gatherings. The under-age Tong is seen smoking in one scene, and June smokes a cigarette in another scene. June also buys paracetamol gum from a street vendor while Tong unsuccessfully attempts to (because paracetamol purchase is illegal for underage persons).
