Moon's Profit and Loss

This film tells the love story of Ken Koyamauchi (played by Hiroshi Oizumi), a man who lost his wife (played by Yuki Shibasaki) and his daughter at the same time due to an accident. One day, a man who calls himself Tetsuhiko Miguro (played by Ren Meguro) comes to Koyamauchi Ken who is in grief and tells Koyamauchi that his daughter wanted to come to see him who he had never met on the day of the accident, and the story between him and another woman he once loved deeply, Ruri (played by Arimura Kasumi). Taking this as an opportunity, seemingly unrelated couples and former lovers are connected, weaving a tortuous and grand love trajectory. Why are you born in this world? Who do you love in this life? Is the mysterious woman his dead daughter? Or is it his dead lover? They are so different from each other, yet so similar...
