The Haru and Yuujin of this world went downstairs and walked to the living room. In the living room, their doppelgangers were sitting quietly on Haru's sofa. "Oh, you two are still here, good that means we can talk" the Haru of this world said.

The Haru from another world spoke, "I'm sorry we barraged in like that. You two were having… an intimate moment, and that was rude of us to come in without knocking. Our sincerest apologies." Everyone in the room blushed, recalling the incident.

"Um that's okay." This world's Haru scratched his forehead and gave a weak, unsure smile. "I think the bigger issue here is what is going on?"

"Yeah, I don't think there should be two Harus or two me," this world's Yuujin chimed in. The pair from another world noticed that this Yuujin was wearing brown slacks, but the upper portion of his body was only wearing a black sleeveless shirt, despite how cold it was outside. Haru and Yuujin chalked it up to the other Haru wearing the green sweatshirt of the other Yuujin.

The Yuujin not from this world explained, "we think we might have accidentally stumbled into your world from ours."

"Huh?" Both this world's Haru and Yuujin responded, a bit taken back by the explanation.

The other Haru explained to them what happened earlier. "You see, before we came here, both Yuujin and I were walking to my place when we got hit with a highly charged purple light. We were trapped for roughly three to four seconds and then we ended up here."

This world's Yuujin paranoia flared up and was unconvinced of their alibi. "So, what you are saying is that this sudden beam of light is the reason you are in our world? Sounds like crazy talk to me."

"Is it really?" the other world Haru asked. "I mean is anything impossible in a world where Appmon exist?" He decided to name drop Appmon to see if it would help lower their suspicions on them.

"So, you two are Appli Drivers?" Haru asked.

"Yep!" The pair from a different world pulled out their Appli Driver Duos. They were the same color and designs as this world's pair.

It made sense that their doubles would be Apple Drivers too. The couple surmised that if their "twins" were both Appli Drivers, then it must mean that the Minerva from their world trusted them, so they would too.

"Okay," Yuujin said, "your story checks out, for now." Haru offered a laugh to his boyfriend's response, but inside he was a bit annoyed that he still held suspicions about them.

Haru from the other world raised his hand to get their attention, and when he received it, he posed his question, "um, where is Gatchmon?"

"And Offmon?" his Yuujin added.

The Haru from this world replied, "they are with Eri-san. Eri-san wanted to reward all the Appmon for all the help they have provided over the years, so she is holding a private concert with her friends for our Appmon. All the Appli Drivers, Ai-chan, grandpa, and Hajime-kun were invited to go as well."

The other Haru asked them an innocent question, "and you didn't go why?" Yet, after asking that question, both this world's Haru and Yuujin had matching crimson red face, so he figured he must have crossed an unknown boundary.

"None of your business!" Haru and Yuujin yelled in unison. Truth be told, they wanted to go, but they also were teenagers and hadn't been intimate with each other in weeks due to how noisy Gatchmon and Offmon are. Not to mention, Haru felt uncomfortable in engaging in lewd acts while his mother was home. Technically, he could still be intimate with his boyfriend, since Yuujin slept in the same room as him and he had permission to lock his room. However, if his mother by some slim chance found out, she would never let him live it down. That and he knew his mother would blog about it.

A few awkward moments later and this world's Haru popped the question. "Now the better question is how to get you two back home?"

Just then a familiar, but unexpected voice rang out, "why are there two Harus and two Yuujin Shinkais in the room?"

The man was the same age as all the occupants in the room. He was slightly above average height and had greyish green wavy unruly hair with red eyes. The young man wore black hooded jacket and dark blue pants with white zippers all over it. Next to him was his Buddy Appmon, Hackmon, a black colored draconic and canine looking creature with a blue cape and monster hood.

This world's Haru's immediate response was to call out his friend's name. "Rei-kun!?"

"Shinkai?" The other world's Yuujin said to himself.

"How did you get in?" Yuujin asked.

Hackmon pointed to the door that was now closed. "The door was slightly open, Rei was worried something happened."

"Hackmon…" Rei tried scolding his Buddy Appmon, but decided to save it for when they got home. "Never mind how I came in, I originally came here to get my special cooking book back."

Haru asked Rei to lend it to him because the book had a special chapter on pasta, and Haru knew how much his cybernetic lover enjoyed the dish. "Oh, why do you need it back so soon? Does it have to do with your anniversary with Ai-chan coming soon?"

Rei gave a slow nod and this world's Yuujin flashed him a small grin.

"Anniversary with Ai-chan?" the other world's Haru chirped.

"Is something wrong? Rei-kun and Ai-chan have been together for almost a year. Next Wednesday will be their anniversary," this world's Haru responded.

The other world's Haru couldn't believe what he had just been told. "What!?"

"What's wrong? Did I say something odd?"

The Yuujin from another world put a hand on his best friend's back to calm him down. "Sorry about that. Haru might be a little shocked because you see in our world he is dating Ai-chan. Rei is kinda dating one of Eri's coworkers."

Haru of this world pointed fingers at them and asked, "what? You mean you two aren't dating?"

"Um no. Um we are not gay…" the other world's Haru said, regretting the poor choice of words he used.

"Oh well you probably already know that my Yuujin and I are a couple." Haru soon blushed realizing how dumb and awkward that statement sounded after they had been caught having sex. Yuujin blushed too after hearing Haru address him as "my Yuujin." He found Haru's hidden possessive side for him to be adorable.

Rei started to fake cough to remind the other occupants in the room of his presence. When he came inside the Shinkai residence, he didn't expect something like this. The current situation was too much for him to handle. He'd rather listen to his little brother and Haru's grandfather, Denemon Shinkai, go on a four-hour tirade about how to better perfect AI. "Can we go back to the real issue at hand? Explain to Hackmon and I what happened and then you all can go back to talking about your love lives and hopefully not mine."

The other Haru and Yuujin offered him the same explanation they gave their counterparts. Rei, however, wasn't entirely convinced.

"Can the Haru and Yuujin Shinkai of my world come into the kitchen."

"Huh?" Both Haru and Yuujin replied before the pair were dragged by Rei into Haru's kitchen.

"Rei-kun that wasn't very nice." Haru rubbed the arm that Rei grabbed him with, feigning that Rei pulled him too hard.

Rei ignored Haru. "Their story seems convincing; however, I'm concern that it might not be the case."

Yuujin let out a smug grin. "See Haru, Rei also thinks they might be androids disguised to look like us."

When it came to these situations, Rei and Yuujin being on the same wavelength usually meant Haru had to accept whatever plan they came up with. "Ugh, Rei-kun why do you love to encourage my boyfriend's paranoia?"

Rei quickly responded, "It's better to err on the side of caution, or did you forget what happened last time you failed to heed my warning?" Rei let out a tiny grin after saying that. He was never going to let Haru live that moment down.

Haru put his hands in the air and waved them showing he had accepted defeat. "Ok fine, you two can have it your way, I'm clearly outnumbered."

"Yuujin Shinkai use your sensors and see if you detect any oddities in them, such as lack of organic material." Over the last year or so, Rei had made some security upgrades to Yuujin's body. One of the most important was making his android friend be impenetrable from hackers or malignant AI. Detection sensors were a minor feature added to ensure Yuujin could spot any threat. Yuujin easily accepted all the security upgrades that Rei placed in him, much to Haru's annoyance.

"Roger," was all Yuujin said. He went back to the living room and did a quick scan on them. The scan was invisible to the naked eye and neither of them noticed anything odd besides Yuujin standing there silently and observing them.

"No, they both are human…" Yuujin thought to himself how was it possible for that young man who appeared similar him to be human? A whole host of theories ran through his mind, none of them pleasant.

However, Yuujin stopped his thinking when Haru asked, "Yuujin are you okay?"

"Yeah sorry I got lost in thought." Yuujin realized it was best to drop this to avoid his partner worrying about him.

However, Yuujin wasn't the only affected by the surprising news. Haru began to think after being told that the Yuujin from another world was human. His mind wandered to the idea of a human Yuujin. However, he quickly brushed that idea from his mind. No, it doesn't matter if Yuujin isn't human, he is my Yuujin and nothing will ever change that. He will always be my Yuujin.

The three friends left the kitchen and returned to the others. Hackmon stayed behind. Over the years, Hackmon and Rei had developed an almost telepathic bond. Hackmon stayed behind on orders from Rei to ensure that the two other "worlders" didn't attempt a run to the exit.

While in the kitchen and talking with the couple, Rei had come up with a plan on how to handle their "guests." "So that's it? Parallel worlds? Alright this might take a while, it would be easier if we had Haru's Appmon with us, or his grandfather, or my brother. Nonetheless, Hackmon and I will try our best to find out what information we can on the Deep Web."

"What can we do?" the Yuujin from a different world asked.

"Unless we need further information, nothing for now," Rei responded.

"Will let you know once we find any clues on how to assist the doubles," Hackmon added. Both Rei and Hackmon went to Haru's kitchen table. Rei pulled out his laptop, thus beginning their search.

The pair of "duplicates" were sitting quietly for a while looking around the room, when the Haru from this world broke the silence. "So, I guess we just wait. Well it couldn't hurt to talk to one another, right? Besides, it will be interesting to learn how it's like on the other side."

His Yuujin agreed. "Yeah, it's not like they are time travelers and can't alter the present."

"Yuujin Shinkai?" The redhead from the other world was mildly curious on why his double had a different family name than him. He wanted to know how that was the case. Was he not adopted by Ms. Oozora like he was? Was this Haru and Yuujin step-siblings?

It took a few seconds before Yuujin responded to his look alike. "Oh, um I changed my family name after Haru's mother adopted me. Oozora isn't even my "mother's" surname." Yuujin started to tighten his hands into fists as he continued his explanation for why he had Haru's last name. "The women I thought I knew my whole life wasn't my mother. She was just a criminal that worked for Leviathan. She used me to hurt Haru." Haru reaches out to Yuujin and begins to rub his arm to soothe him. Haru knew it was a painful experience for Yuujin to remember his traitorous mother, someone he thought that loved him but didn't. And unlike what Haru experienced, it didn't turn out to be a lie, it was reality.

Yuujin gave an apologetic look after hearing this world's Yuujin's story. "Oh, I'm really sorry to hear that. I shouldn't have brought that up. My mother adopted me when I was ten. She worked for L-Corp but was in no way associated with Leviathan."

Silence filled the room as both parties felt a little uncomfortable with the conversation that transpired between the two Yuujins. The silence was broken from the Haru not from this world. "It seems there are stark differences between our world and yours. How about we each talk to our fellow twin, one-on-one? We might learn something more about ourselves we never knew about." While it seemed like an innocent request, he had a hidden motive for why he wanted to talk to the other Haru, away from both Yuujins.

This world's Haru was uncertain about that request, "Um, I don't know." He was concerned that the other Yuujin would unknowingly saying something that could be triggering to his boyfriend again.

Yuujin took notice of how his lover's reaction to the other Haru's suggestion. He knew it had to do with his previous interaction with his "twin." He decided to let his mate know that he was alright. He grabbed his boyfriend's hand with his and gave it a nice squeeze and showed him a warm, gentle smile. "Let's do it Haru, it could be fun."
