(Y/n)'s POV

~ • ~

It was really early in the morning. Though, I'd like to refer to it as late night. Two a.m to be more specific. I was in the library, at a table, with some homemade tea. The worst kind, but Toriel made hers significantly well.

I was reading a book. A romance, but those were the only ones I liked to read in the late-early mornings.

Usually I looked like crap when coming in these hours, but I had no one to impress. My hair tied up in a sloppy bun, a thick sweatshirt that said "I Don't Do Mornings" and some sweatpants.

I said some of those words aloud, very few people were in the library anyway so it didn't bother anyone. My lips felt dry, so I'd need to buy some lip balm. Taking a sip of my tea I heard a familiar voice.

"Awful coincidences, hasn't it?" I blink. That makes no sense. When I saw the originator of the familiar voice I flinch.

"G-Gaster...?! U-uh... what are you doing here? O-or up this late o-or where are your kids...?!" I'm not good at conversation, I pouted mentally whilst on the outside freaking out. Mostly because he's seeing me in my worst state possible.

"I'm always up this late, plus they're asleep at home. What are you doing up this late? A human requires sleep. You shouldn't even be up." He said, joining me at my table, he had a journal. I scratch the back of my head, feeling embarrassed and quickly tried to change the topic.

"L-let's not talk about me... w-what about you? What's with the journal book thing...?" I ask, he looked like he wasn't going along with any of my bull shit.

"(Y/n)." He said, "what are you doing here?"

I sigh deeply, it's hard to think of an excuse when you're tired. I look at my book and sigh again.

"Nightmares... whenever I get nightmares I come to the library and read." I almost whispered, feeling embarrassed over my own problems. After the small silence gap, he spoke again.

"Would you like to talk about them?" I freeze and look at him in shock. After catching my stare he looked like away slightly and continues, "Sans and Papyrus used to have nightmares, all the time. I've found that talking to someone about them is healthy." I smiled at him.

"Please... if I needed to talk to someone I'd get a therapist..." I say, knowing I just met him I didn't want to ruin any chance of a relationship. He raised a brow at me.

"I don't think you'd do that even if you say you would." I blink, how could he know anything about me.

"What makes you say that?" I question, knowing he was right.

"Well based on my deductions from observations, you believe that if you deserve something, you should get something. Based on your behaviors, I don't think you'd use your parents money for therapy, since it is expensive, not to mention, people who need therapy somewhat deny it and keep everything to themselves. So please. Enlighten me on your troubling dreams."

I blink. Is this what having a friend is like? I sigh, giving up. He was good at this, and I was weak.

"I don't know what my nightmares are about... but they scare me and... I don't know... gives me a sense of déjà vu." I think about them for a second, seeing him nod. He was being... patient and listening.

"I see someone... dressed in a cloak and with eyes similar to mine... but it's not... it's not me. He... was with someone... I can never see who. He was always surrounded by humans and monsters... friendly to both... but the weirdest thing... is... it's not in present times...."

"And sometimes... I see what I'd describe as a monster b-but I don't want it to sound offensive... s-so... I'll just have to describe it as a creature that holds a threatening glare..."

He nodded, thinking about it. I look at him and he looked at the table.

"Anything else?" He asked, I thought about it.

"Just some fighting... there is this one dream... I see a soul... but that doesn't make any sense to me because I don't have one..."

Suddenly, instead of patience, his eyes went wide and he stared at me. I freaked out.

"D-did I say something wrong...?!" I freaked out, feeling like suddenly crying. He noticed me freaking out and shook his head.

"No, it's just that everybody has one... are you sure you just don't know how to call it?" I nod.

"I-I'm sure... my mom loves souls so whenever she was home she'd always try to summon mine or have me summon it... but... it never works. So I was just told I don't have one. Plenty of people have tried. It never works." I sigh.

He nods, understanding, probably still wondering how it works. He noticed I looked a bit more uncomfortable than before so he decided to change the subject.

"So what are you reading?" He asked, looking at my book.

"Erase The Future... I-it's a romance." I said, feeling embarrassed for reading a romance. He raised a brow.

"Sounds interesting... what is it about?" He asked, he seemed like he was interested, maybe he'd read it later. Uh oh, am I staring? Uh. I should just read the synopsis.

"When boundaries are made within the space time continuum, mistakes are made within them. Two Errors spend their lives traveling throughout the continuum to fix the mistakes. This however is suicide. Though, how could they bring themselves to fall if they don't want to lose one another." I read aloud. I thought I should explain myself, but I probably wouldn't do that if I had a better conscious.

"I-I just like romance books, they take my mind off of things. P-plus they're emotions I've never really experienced so I figured it wouldn't hurt to read..." I laugh nervously, feeling like I've only dug the hole of my embarrassment deeper.

"You don't need to explain yourself." He chuckles, "it's alright to take interest in something."

His laugh calmed me down. I blushed when a question I've been dying to ask came into my head.

"I don't mean to be blunt, but what does the underground look like?" I ask, looking at him with hints of curiosity shining in my eyes. He looked taken aback. I freaked out.

"I-I'm Sorry... f-forget I asked." I frowned and looked at my lap, I thought I offended him. I heard him start laughing.

"I'm sorry, I'm just surprised." I perk up my head and look at him confused. "I wouldn't think a human would want to see where they imprisoned us."

If I said I was offended, that would be wrong. I just felt bad. I frowned.

"I don't think anyone deserved anything like that... and unfortunately that was in control of a group full of hatred. If there is one thing I'd like to believe that we all have in common is that we choose to dislike the things we can't understand... then that causes war and corruption..."

"A-and I'm really not the type of person to face those challenges. Fight or flight I guess." I rambled again, scratching the back of my head. I hear him get up, so I look up at him.

"If you'd really like to see, I wouldn't mind being a guide." He walked to my side of the table and put out his hand. I blushed and take his hand, getting up. I put my book in my new backpack purse and suddenly we were somewhere else.

I felt a bit sick, I felt my drink in my hand suddenly as it replaced Gaster's hand. I looked at him, feeling a bit nauseous.

"I've never teleported a human before, so if you start to not feel well, let me know, but I think your drink will help." I nod and look up. "Ah. This is the entrance to the underground. Well... it was our exit and currently it is our entrance."

I look at him and nod with a smile. This was interesting. We entered together, everything looked golden and royal.

"This is the old castle. Our king Asgore lived here." He said, then I remembered Toriel.

"Did Toriel use to live with him...? She told me they remarried, b-but either way I don't have all the facts..." I whisper.

"She lived with him in the beginning, then when humans who fell started dying well... they divorced and she left to the Ruins, or as I knew it as a child, First Home." I nodded to his words, he seemed attach to this place but also like he didn't want to be here.

We soon exited the home and saw a garden of golden flowers. He stepped on them no problem but I tried my best not to. He kept telling me that it didn't matter because no one ever came down here unless they were still retrieving their belongings.

Suddenly, there was a beautiful view of a city and the silhouette of the castle I didn't realize we had gotten so far from. It was so beautiful. My eyes were on the city. His on me.

Third Person Perspective

~ • ~

Gaster stared at the woman he had only met the other day. He was curious. She was different. Why was she different. He wanted to study her behavior, she's acted so strange.

He'd have to get a notebook and keep an eye on her. Then when he's not around, Sans could keep an eye on her. Though, Sans already did because he was suspicious of the woman who quite literally stumbled into their lives whom his brother, Papyrus, quite likes.

After a while of admiring the view(s), they continued forth. They arrived in Hotlands and (Y/n) started to sweat.

"Ugh... now I wish I wore something under this." She pouted aloud, to which Gaster chuckled.

They soon arrived to a big, bluish grey building labeled "LAB". (Y/n) stared, wondering why they were there and why they'd have one.

"And this is my old lab." Gaster started, making (Y/n) shrink in her skin. She was surprised. She didn't expect him to be one.

"Oh! I didn't know you were a scientist!" She exclaimed, Gaster nodded and chuckled.

"Really? People usually tell me it's obvious." Which just made (Y/n) feel stupid if everyone could tell but she couldn't. She scratches the back of her head awkwardly as they entered.

Suddenly, she felt a feeling of woah enlighten her embarrassment. Even though the lab was covered in files and papers and tubes of all sorts, it looked like he loved the thing he did and that he did it well and that's what made her feel happy.

"You sure look like an amazing scientist." She complimented, looking around. He felt his soul warm to that comment.

"Thank you, I'm still moving into my new lab." He said, content smile on his skull. He watched as she looked around. "We should keep walking, the next place is much better."
