Undertale : Gaster Chronicles

Chapter 2 , The Teenager

Teenager , one of the periods i barely remember.
The reason stays unknown for me till these days , but , its understandable, after all ,  i should be much older then i was before the...accident.
It started with me getting to finish the University as i've mentioned earlier. My "family" might have slightly cared about me , but they were completely unneeded to me as they barely supported me in anything. I escaped , taking some useful things like Clothes , and then started to live personally. I don't remember my job , but it was something science-machinery related. It was pretty interesting for me back then. But i slightly remember how things started going wrong in lives of Humans and Monsters.
More conflicts started to occur , and it ruined me back in those days. I think that's really the only reason i barely remember that....
But anyway , the situation got worse each day , and i was peacefully working , but , my partners were surprised with me having the ability to bleed , and it made most of them split into those who somehow liked me , and those who disliked me due to the already mentioned events. It didn't matter anymore though , as i was doing my job. But well , the war began weeks later.
And it was pure chaos anyone could imagine.
Deaths , pain , the suffering we all had to feel. I had to repeatedly hide from any attacks and "resistance" from monsters. It was horrifying , watching everyone die like this. A complete genocide.
I survived till its end , and alongside the others got sealed inside the Underground , where i had to adapt to the new changes of life and location in general. I was afraid of everything , but due to my knowledge , the fear didn't last long...
Maximum i could remember at this point.
There's no need to describe how some peaceful monsters became more violent and angry. How any time a human came , they all died. But it all changed once , when royal guards did let me meet King Asgore himself....or something like that.
