Tôi Koe, Shizuka na Kurashi (1988)

Siblings Maisie and Tony, along with their mother, gather for their sister Eileen's wedding. It is a joyous occasion, but through flashbacks, it becomes clear that the family was not always happy. Their father was physically abusive to his wife and left the children emotionally traumatized. As a result, the children have grown into unhappy adults, looking for love they didn't receive when they were young.
