[1] It premiered in Japan on February 4, 2017, and was also released in other territories including China and South Korea.

The film begins with a young Aoi Hinata sitting on a bench, upset about the broken record in her hands.

Immediately it's the present day and university student Aoi Hinata (Miwa) drops the book she's holding and jerks awake, disrupting the class.

Practice goes smoothly after that and Riku quickly announces that he has other things to do, to the confusion and bewilderment of his band members.

In preparation for their concert on Sunday, July 31, the crew put up flyers and paint signs.

Once the band's all packed and ready, Naoya pulls Riku aside and tells him he plans to confess to Aoi at the shrines.

Crying and walking, she pulls out her handkerchief to wipe her tears, but lets a piece of the song lyrics fall out.

Later on, the two sit in front of a sunset, where Riku reveals that he knows how Aoi died that day.

He reveals his secret: he's been cheating with his record player of life, which gives him the ability to go back in time.

She had broken her late father's record and went to Riku's uncle's shop to ask if he could fix.

From then on, he asks his uncle to teach guitar, turning back time until he's able to play the song on the record for Aoi.

The day before the concert rolls around and Riku is visibly unsettled and concerned, while Aoi assumes he's upset about her leaving for London.

Later that night, while the two are writing the new song, Aoi doesn't recognizes some of the lyrics and realizes that Riku has time skipped.

After consistently skipping practice, Riku gets into a fight with the rest of the band members and walks away.

Aoi overhears their conversation and realizes the reason she could remember the one time she died was because Riku had sacrificed his life for hers.

As Riku is about to time travel, Aoi remembers their vibrant summer together and takes the record of life and snaps it in half.

While Aoi takes time to fully accept that her final day is approaching, Riku's uncle pauses by his door to tell his story: his wife had been diagnosed with cancer and had felt that her husband had been distant lately, fully unaware that he was time traveling.

Moved, Riku apologizes to Naoya and Tetta for lashing out at them and begs them to learn Aoi's new song.

Riku draws her close and reassures that he will be there for her always and that he wants to spend his time living life with Aoi.

When the song ends, the fireworks that Aoi had mused about a long time ago go off and she admires how pretty they are.

Facing the ocean, the crew, dress in all-black, stand along the edge, an empty space indicating that Aoi has passed away.

She comforts Riku and encourages him to be strong and move forward, to live a vibrant life.

She exclaims that this is his 100th birthday present and plays her last song to him, thanking him for loving her and for their precious memories.

As Aoi's song continues to play in the background, Riku begins to move on with his life.
