In Rainbow Song, the story begins with the heroine’s death, which immediately reverses the usual romance structure. Instead of watching two people fall in love, we watch the main character recall a relationship that never fully became one. What made it work was the gradual deepening of emotional closeness without confession, combined with the audience’s knowledge that she is already gone. The more intimate the memories become, the more painful the regret feels, both for him and for us. It stayed with me because the film makes us realize, too late, that she may have been a better partner than the one he chose in the present.
