In the movie "Orange"(When the oranges are ripe), the male lead held an ice bucket to cool down the female lead. When the female protagonist's mother saw the male protagonist and the female protagonist meeting in the Motel, she was very angry and uneasy because the female protagonist's mother thought that the relationship between the male protagonist and the female protagonist was unusual. Therefore, the male protagonist took an ice bucket and waited outside the female protagonist's room for a while, waiting for the female protagonist to calm down before going in to talk to her. This way, the male lead could explain his relationship with the female lead and avoid the female lead's mother misunderstanding their relationship.
