The time leading up to Independence Day passed quietly and at the normal pace in the steam city. On the one hand, things at school were monotonously routine, for Nobita and Doraemon they were days of going to the practice room to prepare for the mission, the boy continued practicing to improve his mechanic skill consciously under the tutelage of Mia, the main mechanic of Suchimu Corp. Although it wasn't going as he wanted, it was the skill that was difficult for him to handle at 100%, it improved a little but was still somewhat slow.

After having patched things up with his school friends, he spent the 2 months without having attacks in a row, plus the nightmare that had changed drastically had returned to its original version, although he couldn't get rid of it yet, it wasn't as intense anymore.

But while in Sutirushiti things were happening calmly and without major problems, two nights before Independence Day where the fate of the city would be defined, precisely in the underground part of the city where the territory of Baron Kurai was located, the large sinister black building that emanated a large amount of smog from the machinery and the work of the villain's henchmen, he was having a meeting with his right hand woman Katami and a captain of the soldiers who was going to be in command for the ultimately day, they were in his office on the sixth floor.

"The soldiers are ready with their protections and the modified robots are in condition, the airships are checked, loaded with equipment and fuel; and the explosives are in their positions." The captain of the dark soldiers who wore a costume similar to the soldiers of the Second World War but with decorations of red gears and with a gas mask to avoid being identified gave his final report.

Baron Kurai was without the samurai helmet on showing his face, but he gave a satisfied smile. Katami was polishing a modified long-barreled ray gun on the cabinet near his boss's desk. "Very well captain. As for the inventors and mechanics that we have been using on a (voluntary) basis, proceed to do that" The captain obeys with a bow and leaves the baron's office. "It's not long now, Katami, soon we will take over Sutirushiti and its inhabitants will bow at our feet, but it is only the beginning. Once the city falls into my hands, we will proceed to extend our rule in the following cities to Sutirushiti, little by little ALL the territory will be ours, then the region and in the end...The world will belong to the strong and the weak will have to prostrate themselves in front of us!"

"Thank goodness we were able to steal their action plan, since Suchimu Corp is allied with the Special Forces, they believe they are a saving force that can stop us, PATHETIC" Katami takes out the folder that he had stolen from the factory president's office and checks it. "Create an action plan with a sabotage team to dismantle the airships and bombs precisely on the morning of Independence Day to send the special forces to do the rest when they don't work precisely in the results of the Patent Competition? What a predictable thing. As if dismantling were something quick. Luckily we have some soldiers who will be in charge of taking care of everything that day and we have set traps at all the entrances to the lair, that sabotage team is going to be the first to fall due to that guy's recklessness"

"It seems that Mr. Hirano's anger made him put together a very pathetic plan, and I thought that he was like his father. Getting distracted with his children was his mistake and now we are one step ahead of them" says the baron, or rather, Professor Matsuyama. "And to think that my creation is now in his hands. Arms, legs, a nerve stimulator, bionic eyes? They're nothing compared to the versatility of the Mechanical Engine!"

"I thought that was also an invention of Professor Hirano and a certain Professor Hideki, boss. That's why he created the other special prosthetics" Katami says, surprised because even though she had been working for him for years, she didn't know anything about the past of the engine, but due to recent events, everything was coming to light.

"Yes, Professor Hideki was one of my aliases to interact among the weak and it was thanks to the weak guy that the engine was possible, but it was also my blueprints and my instructions that the idea was born. After my disappearance 50 years ago, I returned to the world I discarded with a mask pretending to be a talented inventor just to begin the elaboration of this plan, years passed and I created the blueprint of an engine that could be used on humans with detailed instructions just so I could use it on myself fooling that pathetic professor. But I had to take a leave of absence because they were secretly investigating my alias and I had to disappear again and let the guy do the job for me to see if it was worth using it to my advantage."

"The guy lied to me telling me that this engine was going to be a failure and would turn off forever when trying to use it on humans. But I ended up finding out that not only that motivated him to make prostheses for other parts of the body that reached that level, but that guy passed the engine to his son, readapting the idea of an engine to a mechanical heart so that it works like a human heart, doing tests with volunteers! And when I realized it, it was already too late."

-Baron Kurai's hideout, months ago-

Professor Matsuyama was in his office maintaining his suit when he heard a news story on the radio.

"And in other news, at the Situs hospital it has become known thanks to the information from our reporters of something that seemed impossible: One of the wounded from Baron Kurai's attacks approximately 3 and a half weeks ago woke up from a coma after a transplant of heart was made, but this being a prosthesis replacing a human heart, which seemed like something out of a dream." The professor is startled, but then he thinks that it's a coincidence and continues with his thing while continuing to listen.

"It's incredible, it's something that was thought not to be possible according to experts in cardiology and mechanical prostheses, as if it were a motor for an invention or something like that." Upon hearing the word motor, the professor drops his tools and approaches his radio to hear more clearly "At the moment it isn't possible to interview the person who now carries that heart since Mr. Hirano, the president of Suchimu Corp. denied any entry of journalists to the hospital, especially to that person's room. But so far it's known that is an 11-year-old boy named Nobi Nobita. We will continue to inform you when we have more about this monumental event in mechanical prosthetics and about the incident that happened 3 and a half weeks ago in the Sutirushiti public school's large hall."

"There is no doubt..." At that moment Professor Matsuyama clenches his fists in rage "That's my engine, IT WORKS, I've been fooled!"

"Wow, before you resurfaced as an allied professor with ulterior motives, and now you pretended to be a member of the municipality's inventors for the plan, you are good with masks sir" Katami says impressed. "Is that why you offered to be part of the robbery plan by being the distraction?"

"No doubt. And it's incredible that my engine is now a heart inside a brat, but that day I saw that despite being minimal, it worked just as I thought." The baron stops and looks behind him where there was a notice board, there was posted the photograph of Nobita in which he had received the plaque, he had gotten that from the newspaper and had cut out that image. "With a precise direction, that engine could have potential as a living weapon. It's possible that not even Hirano Jr. himself knows who the real Professor Hideki was and that's why he stupidly used the engine as just another prosthetic."

"With what you told me, sir. That child would have been of great use to us, a human capable of shooting rays from an engine of almost infinite energy. We could have used him as our weapon" Katami only continues polishing the ray guns with a smile

"He chose to be weak just because he thought he was a good child, but I can already give up the motor for lost, if I remove it from his chest, the motor will turn off. But the mind of children is so moldable... There can still be a minimum chance for Heartbreaker to choose the path of the strong." Professor Matsuyama looks at the photo of the boy with a malicious smile.

"Will you try to convince him again, sir?" Katami asks.

"Losing that engine would be a shame if it's used by those who don't deserve it. But if that kid does something else stupid again, I'll have to sacrifice the engine and that's a shame, anyway. Sacrifices have to be made to win wars." Professor just looks out the window smiling while he sticks a knife in the photo right in the boy's chest "Very soon we will meet again, I hope that when it happens, you will be wiser with your decisions, Heartbreaker"

The time finally came, exactly one day before Independence Day. You could feel the atmosphere of excitement and euphoria in Sutirushiti, with people preparing their positions in the city center and workers decorating and preparing everything where the Patent Competition was going to be, you could also see how the warehouses were full of decorated carts For the pre-pageant parade, it was no surprise that it was the most important event of the year.

It was dismissal time at school. Melia had left first, she was waiting for her friends and her brother, she sees them leaving along with the rest of the students who were going straight to their homes, as was normal, there were no classes on Independence Day so it was a good opportunity to play and have fun... And also for a mission

"Okay, we can go to the factory now!" Melia says excitedly.

"Yeah, but first we must stop by my house to see my other bag. I told mom and dad that I was going to sleep at your house today. By the way, I'll also pick up Doraemon." The silly boy says with a little nervousness, which is noticed by Seiya who puts his hand on his shoulder.

"Everything is going to be fine, we have been preparing for this moment, and you have been trying very hard"

Dekisugi nods "That's right Nobi, you have been able to improve your grades and you have also been able to improve your mechanic skills, you will do well, we will see you tomorrow, that's for sure and be careful"

"If you consider improving the fact that the inventions don't explode anymore but I still take a little time, well, I think it's better than nothing." Nobita just sighs "But, I'm ready, we'll see you tomorrow Dekisugi, thanks for everything."

"See you tomorrow Nobita" Shizuka was also nervous, since the real plan was going to be carried out tonight and not on Independence Day as the false plan that had been stolen said, thanks to the effort that the clumsy boy was putting and how motivated he was to do this to save everyone, the good way of seeing him increased even more, to the point that... "Please."

Shizuka takes Nobita by the hands while he blushes at that action and she smiles at him "Promise me I'll see you tomorrow. Okay? We have to go to the theater again."

The silly boy smiled lovingly at her, little by little he was losing his temper with her "I promise. And... There's something I want to tell you." Nobita lets go and shakes his hands quickly "Don't worry, it's nothing bad this time. It's something more... Personal. But I'll tell you on the day of the theater. Ok?" Shizuka also responds with a smile and an "Okay."

And yes: The little disastrous mechanic chose that day to tell him his feelings, he already felt that he was ready and that is why he was more than motivated to make the plan work well, in order for that day to be a reality.

The three say goodbye to Shizuka and Dekisugi while they go to the Nobi house to go see Doraemon, a while longer Shizuka says goodbye to Dekisugi since she had to go to her piano practice since tomorrow she had a presentation with the piano group as one of the events leading up to the main event of Independence Day and her teacher was going to come to her house to check on her progress. When she leaves, Suneo and Gian watch as they leave, the one who was irritated was Suneo who had seen how Nobita got along with that group.

"That should be us, great Gian. The ones who should be friends with the Hiranos, who would spend time with the friend who decided to separate from us. I was already a little happy that they didn't talk to each other 2 months ago and suddenly they hit it off again! It's not fair!" Suneo exclaims while Dekisugi hears that but pretends not to keep hearing it. "Why is a slow-witted fool like Nobita who should still be below us now standing out like this?!" Suneo turns to look at Gian "But I already have an idea to make things like before, we can make him hurt us in front of everyone and then our classmates will treat him like before. Since you are strong and brave Gian, you can go look for it and..."

The dwarf notices how the robust one just walks away "Hey! Where are you going?!"

"To my house, mom said I should help her prepare the store for tomorrow's events, Suneo."

"And what's with the plan to make Nobita go back to how he was before?! If we take advantage of today we can...!" Gian turns to see Suneo

"I'm tired of that, if Nobita is no longer afraid of us, there's no point in it anymore. Likewise, they're going to end up believing him more because of what happened in the incident, so there's no point in trying anymore, do it yourself if you want. I'm already tired." The robust boy ends up leaving school, leaving the dwarf speechless. "I think maybe that angry mechanic girl had a point."

"F-fine, go!" Suneo raises his voice as his friend leaves "I'll do it myself, everything will go back to how it was before this stupid incident that gave Nobita luck and made him believe that he's better than all of us! He thinks that was the best thing that happened to him and it's stupid! If it had happened to me and not Nobita, I would be the center of everyone's attention and he would still be the same useless guy who never should have been revealed against us!"

"You still don't understand, Honekawa?" Suneo turns to see who told him that, Dekisugi approaches him with a look of pity and annoyance "The incident affected us all, many more than others. Seeing everything that happened to Nobi as a blessing is nothing more than underestimating what he experienced, he had to go through a whole process of pain that although I wasn't able to experience it firsthand like him, I was able to witness how painful the transplant and the 72 hours of waiting were."

"He lives every day with the sole idea that he will never be the same again. He believed that because of him, his family and his friends were suffering because of his condition, he has to take medicine every day so that When he has chest attacks, they are as painless as possible and he will have to do so for about 10 more months. He suffers from a constant nightmare and if it weren't for his naps that are useful for this type of situation, he would have deep circles under his eyes. For a while he felt horrible because he thought his friends would have a bad time because of Baron Kurai and that attempt at mental manipulation he tried to instill in him by calling him a creation, feeling like he was an experiment subject. Do you really think that's a stroke of luck?"

Suneo was frozen by everything Dekisugi told him, everything now turned in Nobita's favor, more than because of the incident, but because of the decisions he made after what he experienced, how he decided to help with the program to protect the what mattered to him and how he chose not to be what the Baron wanted him to be. "I'm not asking you to be friends with Nobi, it's obvious that you're not going to be and it's a shame because it would have been nice if we were ALL friends in the end, but you should put that pride aside and have a little more consideration with all things what he's going through. Have a good day, Honekawa."

Dekisugi politely says goodbye and leaves the place, Suneo just looks at how now he was the one who ended up being left alone, at least that was the feeling that the atmosphere emanated after the tremendous passive-aggressive scolding that he had received.

At the Nobi house, while Seiya and Melia were waiting at the entrance, the silly boy had left his school bag to put on a larger bag containing a change of clothes, his pajamas, a toothbrush and his medicine that he had to take every morning. Doraemon sees him and smiles "Are we ready to go?" Nobita smiles and nods, so he goes down the stairs slowly with his friend, his parents were just in the living room-bedroom next to the stairs watching him go down.

So the boy approaches them with a sad smile, he didn't know what was going to happen, but he knew that many things were going to happen tomorrow "Are you already going to the Hirano house? I hope you have fun, after everything you've worked hard in these months, you deserve to have fun at a sleepover." Says Nobisuke who was taking a short break from a job he had in the workshop having some tea.

"Do you carry your medicine with you? Remember that you should take it in the morning" Nobita nods in response to his mother's question "Okay, be careful son" Suddenly Tamako is hugged by Nobita who couldn't resist hugging her while he was crying "What's wrong with you today Nobita? If you're going to come back tomorrow"

"Nothing, mom" Nobita takes off his cap for a moment while smiling with tears in his eyes. "It's just that I wanted to tell them that thank you for everything and for putting up with me when I was clumsier and lazier, I love you and dad very much." They didn't know why their son was saying that but they both get happy and while Tamako hugs him, Nobisuke caresses his head.

"Don't forget that despite everything that's happened, we also love you Nobita, whether there had been an incident or not" Nobisuke says smiling "See you tomorrow and then we'll all go see the Independence Day parade."

Nobita nods and puts on his cap, Doraemon also says goodbye and together they go to the entrance where the boy puts on his boots leaving the house where Seiya and Melia were waiting for them, at that moment a device similar to what Seiya had in the day of the incident blinks, the black-haired boy looks at it and then looks at the three "That's our call, we have to go to the base to prepare. It's finally time"

The silly boy sighs deeply while clenching his fists with a serious look as he looks at Doraemon who had the same look, and both look at the Hirano brothers, it was time to put an end to the actions of the soulless professor "Let's save everyone"
