A Different Doraemon World

One late afternoon...

"Nobita, let's go home already! It's getting late, and your mom will scold you!" Doraemon said anxiously. He was covered in mud and worriedly tried to persuade Nobita. But the boy, drenched in dirt and looking even filthier than Doraemon, kept digging through the muck and grime under the sewer grate without stopping.

That morning, during a playful scuffle at the empty lot, Nobita accidentally caused the bell from Doraemon's collar to fall into the sewer. Determined to retrieve it, Nobita had pried open the grate and, undeterred by the mess, began searching for the bell. Doraemon had tried to persuade him many times, saying he could just buy a new bell, but Nobita stubbornly insisted on finding the lost one. He had been digging relentlessly from morning until now, hoping to recover it.

"Come on, Nobita, that's enough. Let's go home, okay?" Doraemon urged once more.

At last, Nobita stood up. His face fell, and tears welled in his eyes as he sobbed, "I'm so sorry, Doraemon…"

Hearing this, Doraemon gave a warm smile. "It's okay… Come on, let's go home…" He walked over, picked up Nobita's shoes, and handed them to him.

Nobita put on one shoe, his expression still somber. But suddenly, a jingling sound echoed. Surprised, he noticed something inside the shoe. Quickly taking it off, he dumped out the contents, revealing mud and a small golden bell.

"The bell!" both Doraemon and Nobita exclaimed in astonishment. It turned out that during the digging, Nobita had accidentally flung the mud containing the bell, and it had coincidentally landed in his shoe.

The two of them stared blankly at the bell for a moment before bursting into laughter. They couldn't believe how foolish they had been—the bell had been right there all along! Yet neither of them was angry. They simply found the situation hilariously absurd. Nobita laughed uncontrollably, and Doraemon joined in, their joyous laughter resonating through the beautiful twilight.

Memories Flood Back

Tears began to roll down Doraemon's cheeks. Who would have thought that someone like him, a Përjetësia, would one day cry because of humans? Wiping his tears, he choked out, "Humans aren't entirely without good qualities. There are those who think of others, kind-hearted people who are truly precious. But… because they are so kind, they wouldn't agree to leave their species behind and save only themselves… hic…" Doraemon sobbed and continued, "We couldn't force them to leave either. Making such kind, foolish humans watch their species perish would be too cruel…"

"Doraemon…" Nobita's voice quivered, his eyes brimming with tears.

Silence lingered in the sorrowful, blue-tinged space. Only Doraemon's and Nobita's muffled sobs could be heard. After a long while, Kelly and Karen spoke, their voices softened and tinged with emotion, no longer hostile as before: "So, when have you decided to destroy humanity?"

Wiping his tears, Doraemon replied, "This very morning. We created a special device that would silently and peacefully end all human life without harming other species. Once humanity is gone, we planned to relocate the remaining creatures on Earth.

But yesterday, while using the time machine to check the timeline, I accidentally found you two in the time tunnel. When I realized you were from 500 years in the future, I understood that the Përjetësia's plan had failed. That's why I became so panicked, and then… well, you know the rest…"

"I see…" Kelly and Karen whispered.

"So, the device failed for some reason, and humanity persisted, even thriving 500 years later. That's why you now want to relocate humans from 500 years in the future to a new planet, right?"

"Um, yes… We dislike killing, and if the device failed, the extermination plan was put on hold. Moreover, with this universe's instability, we don't want to change history unnecessarily. Since humanity survives 500 years into the future, moving them to a new planet would have less impact than trying another method to eliminate them in 2005…

Now I understand how crucial the solar system's gravitational balance is to this universe's stability. If possible, I want to save Earth as well, then move humanity to a new planet. After all, this universe is far too unstable. Staying here isn't ideal, but I hope humans will change once they're on the new planet. And if they don't…" Doraemon didn't finish his sentence, only shaking his head.

Kelly stepped forward, holding Doraemon's hands. "I can't guarantee we'll succeed, but I'll try to convince everyone. Please, humanity still has hope. Give us time."

"Yes, 500 years have passed. Humans may rely more on robots now, but we've also learned many hard lessons. Humanity is gradually changing. We'll start fresh on the new planet and become better!" Karen vowed earnestly.

"Yeah…" Doraemon nodded toward them, then turned to Nobita, softly murmuring, "Nobita…"

Nobita hung his head silently. Concerned, Karen stepped forward and placed a hand on his shoulder. "Father… Nobita, are you okay?"

Nobita nodded, then looked at Karen gratefully before walking toward Doraemon. Kelly quickly stepped aside. Staring into Doraemon's eyes for a long time, Nobita finally asked softly, "Our friendship wasn't fake, was it?"

"Not in the slightest!" Doraemon answered firmly.

"That's enough… DORAEMON!" Nobita burst into tears, throwing his arms around Doraemon, who gently embraced him in return. This outcome wasn't bad—perhaps it was the best.

"How wonderful," Karen said with a faint, emotional smile.

"Yes, truly wonderful," Kelly agreed, nodding. The blue hue around them remained, but it no longer carried sorrow. Blue, after all, isn't just the color of sadness—it's also the color of hope.
