- My Angel from the Sky - Gaster x Reader

Chapter 10: Piano

"Our lungs inhale over two millions litres of air every day, without even knowing. Their surface area is large enough to cover one side of a tennis court ...!"

You excitedly giggled as you kept leafing through the pages of the various books you were reading.

"Wow ....There are more living organisms on the skin of a single human being than there are human beings on the surface of the earth ...."

You said again with amazement in your voice as you made yourself comfortable on that randomly arranged couch.

"Shut up or get out of here" a serious voice scolded you as you covered your mouth with your hands.

Damn ... It was stronger than you.

"Sorry ..." you added nervously looking back at your books.

You had found plenty in that library inside the lab, and since you didn't have that much to do during your days, except the so boring soul tests to which Gaster submitted you. You just decided that reading wasn't a bad idea after all.

Surprisingly you had found a lot of books regarding the humans anatomy and the most weird facts about the human body.

That was the most interesting thing you had ever read about.

Well about why you were there with him ...

Okay maybe you could say you just took the yard from the inch he had offered you. Strangely you felt much more at ease in a place where there was him, that's why you had started to pass most of the day inside his office reading in silence ...

Well maybe not exactly in silence ... but reading anyway.

He wasn't okay with this at all ... you could see it, but there wasn't much he could do. He had allowed you to stay and since that day you started coming there.

Off course sometimes you couldn't tear your eyes off him while he was working.

You had learnt a few things about him.

For example when he saw something interesting he usually narrowed his eyes and his breath slightly hitched.

While when he was in front of something he didn't understand he always brought his pen to his mouth slightly touching it ,his eyes were so sharp it scared you ... even though it was so funny seeing him in difficulty.

It's not like his attitude had changed towards you, but after that night he seemed much more stressed and he was starting to lose interest in the things that surrounded him.

It was like he was closing himself in a self-created world only him could see and you were starting to wonder what he was seeing.

It all happened after that weird day you had saw for the first time that thing he called 'anomaly'. He hadn't explained to you what that meant yet so you really didn't understand ... but this seemed to stress him out like you had never seen him before.

Sometimes he just left his office lab just to wander around the various corridors and closed himself in those rooms frenetically searching for something.

You didn't even dare to follow him...

Sometimes he seemed so lost in his own thoughts that he stopped in the middle of his work just to gaze at the emptiness of the room, then he just blinked returning to the various files on his monitor and his papers of data.

Also the king had started come by often to check how your soul extraction was progressing. You never showed your face to him and when he was there you just closed yourself inside the white room. His visits always made you anxious ...
