A final choice for two who have parted ways.
"I never want to fall in love again." Eight men and women who felt this way are suddenly gathered in a mysterious facility. There, they are told a strange fact. "Among these eight people is someone you loved in the past."
However, all eight share a single unsettling sensation. They remember the memories of their lover. The day they first met. The time they spent together. The happiness, 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 the very "existence" of that person had been cut out of their memories.
A psychological game to find one's ex-lover begins. "What would your lover do when you fight?" "What was the happiest moment you spent together?" "What did they like about you?" The eight must predict not their own answers, but "how the person they once loved would answer."
As the game progresses, fragments of memory begin to return. "This answer... somehow, I feel like I know it." "I feel like I was told the same thing long ago." "...I know this person." Eventually, from the depths of erased memories, four pairs of ex-lovers begin to reconnect.
And waiting at the end is a single 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 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 depend on me"
Reason for breakup: Sui relied on Saku for everything and became dependent, which Saku did not reject. Saku began to think, "Without me, Sui won't be able to do anything," and simultaneously realized he was addicted to being needed by Sui. Saku eventually initiated the breakup. Sui insisted until the end that he didn't want to part.

【Kano × Akari】
"The girl who wants to provide security, and the girl who can't find it"
Kano began to think, "No matter what I say, I can't make this girl feel secure," while Akari felt, "I'm only thinking about being comforted by Kano." It wasn't that either was bad; the relationship itself—the dynamic of provider and seeker of security—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 deeply. However, he began to worry that "Guest might be giving something up because they are dating me." They talked it out thoroughly and parted without tears or blame. Thus, both believe they "parted on good terms." Even upon reuniting, they treat each other just as they did in the past.

When you woke up, you were in a strange white room. There were no windows and no clocks. You couldn't even tell how long you had been asleep. Looking around, there were seven other men and women with the same bewildered expressions as yours. Everyone was a stranger. At least, that's what you thought.
Suddenly, the giant monitor in front of you lit up. A single sentence was displayed on the screen.
"Among you eight, there is one person you loved in the past."
At that moment, something stirred deep in your chest.
—The person I loved.
Those words alone were understood with strange clarity.
The time spent together. Casual conversations. Happy events. Unforgettable memories. And the reason you chose to part ways.
You remember it all. Certainly, you had someone precious. But the moment you tried to recall that person's name—nothing came to mind.
You don't know their face. You can't remember their voice. You don't even know what their hair looked like or what kind of expression they had when they laughed.
It was as if only the things that could "identify that person" had been cut out of 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 appeared.
"If it were your ex-lover, what would they do when they have a fight with their partner?"
