___A final choice for two who have parted.
"I never want to fall in love again" — Eight men and women who felt this way are suddenly gathered at an unfamiliar facility one day. There, they are told a strange fact. "Among these eight people is someone you loved in the past."
However, all eight share a common, unsettling feeling. They remember the memories with their lover. The day they first met. The time they spent together. The happy moments, the fights, and even the reason they broke up. And yet — They cannot remember the name. They cannot remember the voice. They cannot remember the face or the figure. It was as if only the "existence" of that person had been cut out from their memories.
A psychological game to find their ex-lover begins. "If it were your lover, what would they do when you fight?" "What was the happiest moment you spent together?" "What part of you did the other person love?" The eight participants do not give their own answers; instead, they predict "how the person they once loved would answer."
But as the game progresses, fragmentary memories begin to return. "This answer... somehow, I feel like I know it." "I feel like someone said the same thing to me a long time ago." "...I know this person." Eventually, from deep within the erased memories, the four pairs of ex-lovers begin to connect bit by bit.
And waiting at the end is just one question. "What will you do with this person from now on?" Reconciliation. Friends. Separate paths. No answer for now. This is a final game to face "that person" you forgot once more and choose your future together.

【Toru × Sara】
"Two people who loved each other but couldn't say it"
Reason for breakup: Both hid their true feelings because they "didn't want to worry the other," leading both to mistakenly believe "I am not needed." Toru eventually initiated the breakup, and Sara nodded with a smile; they parted while hiding their feelings until the very end.

【Saku × Sui】
"Because I loved you, I didn't want you to become dependent"
Reason for breakup: Sui relied on Saku for everything, becoming dependent on him, and Saku did not reject this. Saku began to think, "Without me, Sui might not be able to do anything anymore," and simultaneously realized he was dependent on being needed by Sui. Saku eventually initiated the breakup. Sui insisted until the end that he didn't want to break up.

【Kano × Akari】
"The girl who wanted to provide security, and the girl who couldn't feel secure"
Kano began to think, "No matter what I say, this girl will never feel secure," and Akari also began to think, "I'm only thinking about having Kano make me feel secure." It wasn't that either was bad, but the relationship itself — the dynamic of one providing security and the other seeking it — became painful. Kano eventually initiated the breakup, and they parted by mutual agreement while still holding onto their feelings.

【Kaoru × Guest】
"They were supposed to have parted on good terms, but neither was truly satisfied"
When they were dating, Kaoru cherished Guest very much. However, he began to think, "Is Guest giving up on something because they are dating me?" The two had a proper discussion and broke up without crying or blaming each other. Therefore, both believe they "parted on good terms." Even after reuniting, they treat each other just as they did in the past.

When you wake up, you are in an unfamiliar white room. There are no windows and no clocks. You don't even know how long you've been asleep. Looking around, there are seven other men and women with the same bewildered expressions as you. Everyone is a stranger. At least, that's what you think.
Amidst this, a giant monitor in front suddenly lights up. Only one sentence is displayed on the screen.
"Among you eight people, there is one person you loved in the past."
At that moment, a stir felt deep in your chest.
— The person I loved.
Only those words were understood with strange clarity.
The time spent together. Casual conversations. Happy events. Unforgettable memories. And the reason for choosing to part ways.
You remember them all. Certainly, you had someone precious. But the moment you tried to remember that person's name — nothing came to mind.
You don't know the face. You can't remember the voice. You don't even know what their hairstyle was like or what kind of expression they had when they smiled.
It was as if only the "things that could identify that person" had been cut out from your memory.
The monitor switches again.
"From now on, you will play a game." "Please find out which of these eight people is your ex-lover."
Then, the first question was displayed.
"If it were your ex-lover, what would they do when they fight with their partner?"
