Vergissmeinnicht (2004)

The film follows two elderly people who unexpectedly connect and begin a loving relationship. An older man invites a woman he heard playing the piano to visit a planetarium, sharing stories of his life during their walks. The woman listens intently, expressing genuine interest in everything he says. However, subtle sadness in her goodbyes hints at a deeper issue: the man is suffering from dementia and will forget their meeting the following day. He restarts their courtship each day, and she bravely continues to play along, until a pivotal moment.
