After that horrible deed he did to Mamoru, Sakuma halted all his projects and solely used W41-FU to monitor Mamoru's activity remotely. He told W41-FU to give him news whenever there was a change in Mamoru's normal activity or whenever there was a change in Mamoru's memory.

Although Sakuma was confident that his perfect android wouldn't realize that he was an android, because he completely mimicked what a normal human would do. Even if Mamoru went on X-ray, it would still show a human organ, unless Mamoru went under surgery, then that was inevitable.

Honestly, Sakuma still hated the fact that Amano-San cared a lot about Mamoru. Truthfully, all he wanted was to just destroy this android, and then go on with his real plan. But when he faced Amano-San who smiled at him and rubbed his head, he felt weak.

Whenever they were together, all he wanted to do was just spend time with Amano-San. He wanted to forget all his horrible past, and stayed with Amano-San forever. 

Like today, they were spending time watching a movie from one hundred years ago. It was a movie about a group of superheroes fighting a purple alien with a huge chin. One of the heroes had a red metallic suit and he turned into a superhero by armouring himself with the high-tech suit. 

"I don't feel so good…" Sakuma mimicked the dialogue told by a spider boy. He seemed to be immersed by the story. Sakuma said that he watched this franchise every time he wanted to relax. Because he wanted to be a hero like them, but he couldn't. 

[… we're in 2121 and we still watch avengers? Is this kid for real?]

[Pupa: There is no superhero movie in 2121, because they don't want the young children to have a dream to be a superhero. You see, the technology on 2121 allows people to be a real superhero, the government didn't want the young generation to aspire and rebel against the 'villain'.]

[… suppressing the people since their childhood. The primitive way always works.]

Yunyu glanced at Sakuma who was immersed with the movie, he asked the system;

[What about Mamoru? Is he alright?]

[Pupa: Based on my current data, yes. Reporters surrounded him and asked him what happened. He just said that he didn't remember anything and woke up in his bed.]

[So, Sakuma really erased his memory about me?]

[Pupa: I don't know. But probably yes, because he didn't report anything and continued on with his life as a normal cop again.]

"Amano-San, what are you thinking about? Are you thinking about that guy?" Sakuma smiled as he snuggled on Yukio's chest, "Don't ever think about that guy again or I will kill him, okay?"

Yukio gulped, "I'm not thinking about him. I'm just thinking about you. I still don't know what happened during your childhood. I want to know what caused you to be a shut in."

Sakuma didn't reply for a moment, he clenched Yukio's shirt, as if he tried to force Yukio to ignore his past, but he released it after he realized that it was inevitable. Amano-San wouldn't believe him if he never showed him his past.

"Please promise me that you will not leave me after I told you…" 

"I will not," Yukio smiled, "I told you that we are partners, right? If you want me to be your spouse, then at least trust me."

Sakuma stared at Amano-San for a moment, and then he took one transporter. He clicked the transporter and the door was opened, "I will bring you to my life before I become a shut in."

Sakuma and Yukio entered the transporter and they appeared in a dusty room. It was a small room with a small bed, fitting for a young boy, "This is my original room when I was a kid."

Sakuma guided Yukio to his small bed, the moment Yukio touched that bed for a small boy, he heard a notification from Pupa:

[Pupa: Ding! A hidden plot has been triggered! A tormented boy and police's ignorance.]

Pupa started pouring the second hidden plot on Yunyu's head, the first thing that he saw was a small boy, probably around seven years old, crying in the corner while his parents were gunned down by the cops in front of him.

Sakuma's parents were activists who boldly voiced their opinion about police bribery, brutality and corruption in Neo Yokto. They were very vocal and they would start a public protest, they would also recruit many people to follow their rally.

But people like them were pests for the government. Afraid that the growing protest would soon turn violent, the government ordered the police force to assassinate few important figures in this protest, and Sakuma's parents were gunned down first mercilessly in front of Sakuma's eyes. 

After killing the parents, Sakuma was forcefully thrown to the orphanage and was threatened to never tell people about what happened to his parents. They told him that he was a useless thing, his voice wouldn't be heard and he would be gunned down just like his parents.

Seven years old Sakuma was put in the orphanage and turned into a quiet and gloomy kid. He was physically weak, so he would also be bullied by his peers in the orphanage.

Until a year later, he was adopted by a middle aged woman. She didn't have any child, and she wanted to adopt instead of marrying. Thus, eight years old Sakuma was adopted and lived with this middle aged woman.

But instead of living leisurely, Sakuma would be beaten and treated like a slave at home. Sakuma was physically weak, so he couldn't do household chores alone. He would be beaten and starved whenever he failed to do chores. It was so bad that Sakuma felt like he was already dead.

"You useless thing! I should've adopted someone better!" the middle aged woman yelled while beating Sakuma with a wooden broom until he was bruised. 

Turned out, the middle aged woman wanted to adopt him not because she wanted a child. But she wanted to earn that monthly childcare support for orphans given by the government. Because that was her only way of earning money until Sakuma reached 17 and he would be kicked out of the house.

Sakuma's life was hell, but he found solace in comic books and manga. He grew up as a quiet kid without friends or family he could share his pain with. He made money by doing online jobs, since he was already talented, he could make money by himself and hid his money from his adopted mother. 

Until when he reached twelve years old, when his adopted mother discovered his money and took it all. He tried to take it back, but he was beaten to pulp by his adopted mother. 

Heartbroken and scared, he ran away to the police station and begged the police to take him or return him to the orphanage. Because he couldn't handle it anymore. The police shrugged it off, because they thought that it was nothing serious.

"You trash bastard! I gave you food once a day and you still want to report me?!" 

Every time Sakuma tried to run away and report the abuse to the police, the police shrugged his problem off, simply because it was not worth their time. Sakuma was just an orphan, there was no money or incentive dealing with orphan problems, and it was a sensitive topic. Thus, after four times Sakuma reported it to the police and returned back to his house only to get beaten again and again by his adopted mother, he stopped believing the cops.

He endured everything alone. To escape his pain, he read a lot of superhero comics and books. He was inspired to be a real hero who would help people in need, at least people with the same fate as him. 

But once he was fifteen, he naïvely declared in front of his class that he wanted to be a superhero that protected others. He thought people would at least appreciate his dream. But what he got was a punch in the gut.

He was pulled by the school bully after the school ended and he was punched and tormented by the bully, "You want to be a superhero? You can't even protect yourself! What can you do with your weak body?" 

Sakuma tried to defend himself in vain. But in the desperate act of struggle, he accidentally scratched the bully's face until it left an obvious scar.

Sakuma was taken to the headmaster office with the bully, and he was scolded and threatened by the headmaster, "Don't you see who is his father? His father is the Chief Superintendent in the police force! You are just a trash orphan! Do you want to die?!"

Sakuma was heartbroken because he was the one who got suspended instead of the bully. When he got home, his adopted mother was furious at him and beat him harshly, "You trash orphan! You will put me in danger because of your stupidity!"

Sakuma couldn't bear with all these torments anymore, in the night after his suspension, he ran away from his home, never to be seen again. 

Yunyu returned back to reality, Sakuma told the same story as what Yunyu saw in the hidden plot flashback. 

"Amano-San… I'm sorry that you have to hear this story of mine… I'm a low born, I don't have anyone by my side. That's why I get scared that you will also leave me, because I'm a worthless trash in the society. B—But you promise to never leave me! I will never let you leave me!" Sakuma warned. 

Yukio said nothing and pulled Sakuma to his embrace, "A—Amano-San…"

Yukio hurriedly carried Sakuma back to the transporter and they returned back to the lab, "I will protect you, Sakuma."
