Love Letter

Hiroko Watanabe, living in Kobe, loses her fiancé Itsuki Fujii in a mountain climbing accident. The tragedy shatters her, leaving a deep ache that colors her memories of their time together. Kobe and Itsuki's death become the opening wound of the story.

Two years after the accident, on Itsuki's memorial day, Hiroko browses his high school yearbook and finds an address tucked under his name. She writes a letter to the address, hoping for a sign or closure. Soon she receives a reply from a woman named Itsuki Fujii who bears a striking resemblance to her.

The film toggles between Hiroko's letters and the responses she receives from Itsuki Fujii, a woman who looks almost the same as Hiroko. The correspondence feels miraculous, as if the two Itsukis are connected across memory and fate.

Female Itsuki works at the public library and endures a persistent cold she refuses to treat. Her father died of pneumonia during high school, a memory that shadows her health and choices.

Hiroko shows the letter to Akiba, a friend who then reveals his own feelings for Hiroko. He urges her to move on from Itsuki and suggests the letters might be a sign from beyond, not a miraculous message.

Hiroko and Akiba decide to travel to Otaru, Female Itsuki's hometown, hoping to uncover the truth behind the mysterious correspondence. The plan is framed as a chance to confirm identity and help Hiroko move on.

Before they can meet, Female Itsuki is tricked into going to the hospital, where she falls asleep and dreams of her father's death. The deception sets off a sequence that distances them from a direct confrontation.

Hiroko and Akiba wait outside Female Itsuki's home and leave a letter for her instead of meeting face to face. They catch a fleeting glimpse of each other before parting ways, maintaining the distance between them and the truth.

Back in Kobe, Hiroko realizes there are two Itsuki Fujiis in the yearbook and wonders if her similarity to Female Itsuki is why Itsuki fell for her. She asks Female Itsuki to share high school memories that might explain their inexplicable connection.

Flashbacks reveal Male Itsuki as a shy, peculiar boy who was often paired with Female Itsuki by classmates. The two navigate awkward teenage romance, with a key book exchange that becomes the last memory before his transfer.

Female Itsuki learns that Male Itsuki died in the mountain accident two years earlier. The revelation ties the two Itsukis together in a haunting way and reframes Hiroko's quest for truth.

Hiroko and Akiba visit the mountain where Itsuki died, sharing memories of him as the dawn greets a distant peak. Akiba nudges Hiroko to look toward the sunrise and she calls out Itsuki's name in a mirrored moment.

Meanwhile, Female Itsuki collapses from a fever; the neglected cold has turned into pneumonia, echoing her father's fate. Her mother and grandfather brave a snowstorm to get her to the hospital just in time.

Volunteer girls from Female Itsuki's former high school library visit and bring the book that Male Itsuki gave her to return. They discover his name on the checkout card and a sketch he made of Female Itsuki, but she decides not to send any letter about it.
