Regret.

Shinomiya Kaguya is contemplating what is going on, but before she can continue, Fujiwara Chika approaches her.

"Hey, Kaguya, Yu has been waiting for you in your office. I understand you're still upset over the past, but I hope you'll listen to him."

Fujiwara Chika spoke in a pleading tone.

She walks by her and out of the corridor after telling her that.

Shinomiya Kaguya, on the other hand, couldn't believe it just now.

It's been fifteen years!

This defies logic, no matter what she thought.

She remembered being in the student council room earlier, but no matter how hard she smacked herself, she couldn't shake this dream-like sensation.

This made her realize that what she was witnessing was true.

She is now fifteen years in the future.

Despite this, she continued to look for evidence that she was only dreaming; but, no matter what she tried, she couldn't uncover anything.

Finally, she embraces this fact wholeheartedly.

Unconsciously, she enters the room from where Fujiwara Chika emerged earlier.

She entered and noticed how lovely the space was.

Looking at the designs and furniture, it is clear that they are all her style.

However, this room is her office, which Fujiwara Chika mentioned previously.

She observed a black-haired man wearing red eyeglasses while glancing around the room.

The man is currently seated on the couch, reading a book.

She couldn't help but gulp when she saw the man.

It is none other than Ishigami Yu.

However, after fifteen years, Ishigami Yu appears older and more attractive than she could have imagined.

She couldn't help but fall in love with him again, no matter how she looked at him.

"Oh? What brings you here? "

Shinomiya Kaguya's lips suddenly speak on their own.

Her tone suggests that she doesn't want to see him at all.

Ishigami Yu stops reading when she appears.

He looked at her and said, "I want to say something."

"Just say whatever it is. I don't have as much free time as you do."

Shinomiya Kaguya shouted it vehemently.

Despite her tone and expression, she seems astonished and perplexed by her emotions.

Her emotions are very paradoxical right now.

She really, really, really, really, really, really, really loves him, but she also hates him, really, really, really, really, really, really hates him.

(A/N: If you know the reference, then you know the reference.)

She has no idea where these sentiments came from because she is definitely in love with Ishigami Yu, but her current feelings, despite knowing that they are her feelings, feel weird, as if they did not originate directly from her heart.

In addition, as time passes, the hatred fades.

Ishigami Yu continues to speak while she thinks.

"I'd like you to accompany me. It may be selfish, but I require your strength."

"You're way too selfish—truly selfish. But I respect your bravery. Regrettably, I decline for the third time."

"I see. Please accept my apologies for the inconvenience. This time, I'm going to respect you and never bother you again."

Ishigami Yu then left the room.

Suddenly, the room becomes black, and the scene shifts.

She is currently standing atop someone's tomb in a cemetery.

Her tears fall as she reads the name on the tombstone.

"Ishigami Yu. No way, no how, no, no, NO! "

As the rain falls, she shouts.

She returns to the dark space as the surroundings darken again.

She can feel the guilt she feels for not agreeing to aid him.

Despite her hatred for him, she still loves him.

'What exactly are these memories and emotions? '

She is still perplexed as to where these originated from.

She abruptly returned to the student council room.

But there's something different.

On the sofa sits a woman who resembles her.

"It seems you don't feel good, myself."

"You are?"

"As you can see, I'm you."

"B-but—"

"How, though? That is something we will address in the future. For the time being, we shall discuss your decision. My biggest regret is the one I'm showing you. But first, I let Ishigami decide whether I or the other girls would go, and he obviously chose them over me. This is why I despise him so much and refuse to see him because I believed I would forget my love for him, but I was mistaken. Even though it has been fifteen years, he remains in my heart."

She stood up and followed Shinomiya Kaguya.

"A new timeline has emerged. They say you're a genius, Shinomiya Kaguya, but sometimes you have to swallow your pride because you might regret it later. Being their sister is also not all horrible. I investigate them almost every day, so—anyway, I realize there's no credit to my comments, but I hope you reconsider your decision. I also hope that you will become more powerful than I am. That's all there is to it. I don't have much time, so I'll say good-bye."

"WAIT!"

However, the image darkens again, and when she opens her eyes, she sees Kasumigaoka Utaha sitting in front of her.

When she saw her, she assumed she had already returned.
