This show is about memory, and the repetitions the show allows, with the flashbacks being not for us but for them, they are remembering, and even then in the end we get deeper memories pulled out. It's a beautiful show, well acted, beautifully filmed. Short, but just on top of its story, beginning breakup to end 2nd chance.

It starts with Fumiya breaking up with Ritsu, who runs out has an accident and loses memory. Fumiya then decides to let them fall back in love again, rather than explain the relationship and breakup. Ritsu is suspicious of the attention, but Fumiya clearly is falling back in love, and having trouble with the setup he set up. He's seeing original Ritsu when they first got together again and is having trouble not being with him. First Fumiya's flashbacks give him a chance not just to remember the good times, but to regret what has been lost, to feel like the new situation isn't quite right at all.

And we end with Ristu getting his memories back, including the earliest one of Fumiya, before their official first meeting.

Great use of flashbacks to really show how memory is part of love.
