    This is a story of Horror perspective from the AU I made that I will probably call.. "the casual" (idk I'm still thinking for the name) This story might have alot of sans, frisk, and other bunch but I make them all as a normal human in this story. So no power, soul stuff, or any form of save and load and stuff like that. It's just a normal high school life for this character (tho not too normal). This story is also the continuation of the previous story I make "THE CASUAL MURDER TRIO" (Tho it have worse grammar and usage of word on that one). So if you have the power to endure bad grammar perhaps you'll have to read that first before this one so you'll understand the character a little bit more. . . . . . . . . . . . . . . . . . . . . . . . . . . . . Tho for CONTEXT (spoiler) : Horror got caught by police for being one of the suspect that help fell(sans) to make a ruckus at fresh(sans) party. By ruckus, it mean a literal attempt to murder dust in fresh biggest party of the year. The party end by the defeat of fell, killer escaping to who-knows-where since he's the one who bring fell critical condition and wanted by police, dust passing out, and horror got caught. And two month after the event, this is where horror perspective story start.. the first time where he got separated from his only friends for the longest time. And because of that, his behavior started to change and only god knows what will happened.. (read it to know what god know 🌞)

    This is from the readers point of view. You don't know where you came from. You don't know where you've been. You don't even recognise yourself. You're lying in the street whilst it's pouring it down. Your hurt and alone. Your clothes are in even worse condition than you are. You feel that your going to die there. Until a short, joking skeleton named Sans, Invites you to come and live with him, and his brothers.

    She was ready to give in to her thoughts, but Sans didn't want to let her go ever. Not like this. It's never easy to win a battle where you're struggling to keep your own very self alive. And so, he wanted to give his all to support her through it all. Even if it felt like things weren't getting better for a while. Basically, angst and comfort with reader + Sans. Written in 3rd person's point of view. *Sans in this fic is heavily implied to be Gaster!Sans/Echotale Sans, but you can switch out his nicknames for it to be any AU Sans. *Reader uses she/her pronouns but can be of any gender up to the reader's interpretation. *Sans/Gaster!Sans does not belong to me :) I just write.

A ring, all you had left to remember your mother, and a necklace, all you had left of your father, and this stupid, stupid house. It was lonely. Now you were 18 and looking for a job. You had good grades, and everything you could ask for. Now all you needed was a special...someone.

    TEM HAZ ALL TEH HOOMAN SOULZ! So, will be taking requests for these, BUT! I will not be doing lemons, mainly because I find writing them to be 'hard'. Lol. Anyway, imagination has no limit to all the Sans..es? Sanses? Sans'? No idea. They're just little fluffy moments I imagine. Now, if you excuse me, I will be attending to the hospital. My appendix hurts. I'd say a skeleton joke, but I don't have the 'guts' to. Read this book for Temmie to get higher education.
