“Rei, I’ve brought you some more clothes,” announced Iru, opening a little gap in the curtain and inserting the mentioned clothes inside of the dressing room. However, no hand came to get the clothes. “Rei?”

Iru opened the curtain further and took a peek inside of the small cubic area. He found his ‘Beatrice’ crouched down on the floor, his grey eyes stuck on the mirror that covered the entirety of one of the walls of the dressing area.

“Is something the matter, Rei?” asked Iru, changing his hold on the clothes so he could more easily step inside of the cubicle. His entrance was greeted by a sudden glowing red glare, one that quickly faded away at the realisation of who had come in.

“Iru-kun, no more clothes, please…” sighed Rei, his shoulders slumping down even further as he spotted another small mountain of clothes in Iru’s hands. “I don’t need more clothes…”

“Okay, got it,” acknowledged Iru, dropping the clothes on the floor without any hesitation. He walked closer to Rei and crouched down next to him. “What were you doing?”

“I just realised there are some things I can’t see on my own,” said Rei, switching his gaze back to the mirror. He tilted his head to the left and leaned it on Iru’s shoulder. “I can’t see a portion of my own body most of the time. I wonder what it’s doing when I’m not paying attention to it?”

“It’s only doing what you want it to do,” explained Iru, placing his hand on top of Rei’s head. With a soft smile on his lips, he gently caressed his hair. “Body parts don’t move on their own, they do what the brain tells them to.”

“Would it be a bad thing if the body moved on its own?” inquired Rei, glancing at Iru through the mirror.

“No, most of the time it isn’t,” said Iru, placing a quick peck on the crown of Rei’s head. “This is mostly applied to humans but I’ll still exemplify it. They obviously only have the brain to tell them what to do and control their body. But they divide its control in two. One is instinct, the other is emotions. Sometimes humans do idiotic things because they get carried away by their emotions, especially when they go out of control. But there are times where the body moves on its own when instinct is the one solemnly controlling the body. The body goes into auto-pilot and does what it needs to do to stay alive, sometimes to keep someone else alive.”

“Then the emotions sometimes say something but instinct makes them act in another way?” inquired Rei after thinking about that explanation for a couple of seconds.

“Exactly,” acknowledged Iru with a small nod. “Sometimes the best thing to do is not in accordance with what we want to do. That’s why humans are such conflicting species. Sometimes what their heart tells them to do is bad. Sometimes they need to rip apart their hearts to do the correct thing. And sometimes they do evil things because they never had one, to begin with. But those actions are only bad or good depending on who looks at them. During the Russian attack to the base, the Japanese soldiers saw their invasion as an evil thing. But the Russian soldiers saw the Japanese as the ones in the wrong by misunderstanding the attack they had undergone the previous day.”

“Iru-kun, how do you decide if you should follow your emotions or your instinct?” asked Rei, removing his head from Iru’s shoulder so he could stare straight at him. “How do you decide if what you’re doing is good or bad?”

“There’s no good or bad in what we do, we’re Mass Murder Machines,” pointed out Iru with a quick shrug of his shoulders. He then motioned his hands forward, gently caging Rei’s face with the palm of his hands. Iru leaned his head forward and lovingly kissed Rei’s lips. “But personally, my main deciding factor is you, Rei. I always do, or try to do, what is best for you and for what you want to do. And if what you want to do ever turns into a mistake that can hurt you, I’ll make sure to stop you and admonish you plenty.”

“I have the feeling your admonishments would be very troublesome,” chuckled Rei, painting a soft smile on his lips.

“I don’t think that’ll be a future problem for you, to be honest,” added Iru. “We have no ‘heart’ to speak of. What we do is always what we need to do to stay alive. It’s always done under the label of ‘instinct’. There’s no right or wrong in instinct.”

“What is your ‘instinct’ telling you right now?” inquired Rei, tilting his head slightly, despite the hands still present on his cheeks.

“To leave behind all of those troublesome humans and super soldiers alike and enjoy myself with just you in the shopping centre,” said Iru, a mischievous smirk tugging at the corner of his lips. “My patience and tolerance are not as bottomless as yours. I’m sick and tired of having to share my ‘Beatrice’ with everyone else. Should we just sneak out somewhere and enjoy some peace and quiet on our own?”

“I don’t think that would be a good idea,” chuckled Rei, putting his hands on top of Iru’s. “We would get to spend some time alone but then we would return to constant admonishments by five different human soldiers. At the very least. Atsumu-kun would probably also make a fuss about it.”

“See? You’re too much of a goody-two-shoes,” scoffed Iru, once again kissing Rei’s lips. “So if I were to kidnap you somewhere, all of those admonishments would be directed at me only. It’s a perfect balance between us. Yes, it truly can’t be called anything else other than being just one.”

“There you go again, trying to act more evil than you really are,” said Rei, his small smile stretching just a little bit more. He placed his arms around Iru’s neck and gently caressed his head. “That’s why humans always misunderstand everything you do or say.”

“For as long as you don’t misunderstand it, I have absolutely no problems with that,” confessed Iru, leaning his forehead on Rei’s and rubbing the tip of their noses together. “Unlike you, I don’t have the need to act friendly with them,”

“Even though you spend most of your evenings with Mizusaki-kun?” pointed out Rei, an eyebrow slightly arched in accusation.

“Jealous?” asked back Iru, his mischievous smirk becoming even more accentuated on his lips.

“Not as much as you,” countered Rei, an innocent expressionless on his face that contrasted with the soft mischievous glint in his grey eyes. “Your anger makes staying in the rooftop with Murayama-san even chillier.”

“Why, you little…!”

“Ahahaha.”
