A daughter named Natalie was born to a family in France in 1944. On the same day, they also adopted a son named Francis. The siblings grew up joyfully and eventually fell in love during their teenage years. Sadly, Natalie's parents passed away before granting their approval, and their aunt who became Natalie's guardian strongly opposed their relationship. Desperate and hopeless, the two fled and attempted suicide. However, they both survived and tragically lost track of each other.
Many years later, Natalie discovered the shocking truth about Francis's life, including his marriage and child. Despite enduring immense difficulties, she resolved to care for his son. She's inundated with memories of her past love, and even more so as the child bears an eerie resemblance to him.
