You and Sans were already a couple, which you were so glad about. He gave you a golden locket to symbolize his love for you. What you don't know is what lies inside it... 

3 months after his confession for you, he found something interesting in his father's old lab. Alternate Universes, also known as AUs, has been appearing in their world here and there; because of a certain someone. Some people were corrupted because of it, and you must save them. The Sanses you meet in each Universe wants to help you, and you are the only one who can permanently close them from being opened again once and for all. After all, you're the monsters' only hope left...

A story which the reader has to be the main character. Book cover rightfully belongs to MelodiousRed (aka me). Have fun! ^-^

"I'm bleeding...but it seems as if my fears have vanished as I stare at the male before me. He gazes at me with such intensity and I can't help but feel...compelled by his alluring crimson eyes. A feeling of felicity bubbled within my stomach. It was weird...since this man kidnaped me and all, but...I wasn't afraid-not a sense of qualm within my body. I was relaxed and eased...I wasn't afraid, which I guess, made me enjoy his presence. He was a God and I was the measly beggar before him...Oh, how I just wanted him to hold me...wait...what am I saying? "'Snap out of it Blu! He kidnaped you! This isn't some Stockholm Syndrome thriller! He's going to kill you if you don't do something!!'" Despite the edge my conscious clearly announced, I felt at peace. I was happy-no anxiety, no sadness...just bliss...he treated me well and I loved him...but, did he feel the same?" - This is kind of like an AU? Like Chara is an actual human not a video game character, along with Frisk who pops in or is mentioned a few times throughout the story. This story contains smut (it's shitty regardless, lol) and swearing, maybe, and it's between two males. If you're not into gay stuff, then this story is not the right one for you. :) It's also written in third person, not first person, like the description is...oops? Disclaimer: I do not own Chara or Frisk, I just own the plot and the character Blu, his family, and that's about it...

Remaster on my page - check it out! Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that he wishes could remain a secret. But when the questions start being asked, what does he do? These questions seem so little, yet they cause so much to happen. One little question. "Who is ??????" can change so much. A chain reaction from a single sentence can cause an entire world to crumble. Or maybe two. This is my first book so dont expect anything great. Inspirations: The "Better Times" trilogy by: @ANinnyMouse42 "Royal Blue" by: @dealialestine Started: 24th May 2021 Finished: 29th December 2021 A full 7 months of great fun with this book!
