Heart-Tale (Sans x Frisk - Undertale AU)

After Frisk reaches the surface, she comes across Chara. Her body becomes possessed by him.
In her agony, she sees the deaths of her friends and the one she loves: Sans.
Can Sans see the truth or will he not trust her?

(This story is an AU where Frisk is a female, who is 22 years old. She is not a child in this. I do not like shipping Frisk when she's a kid. She can be referred as they/them so no gender war comments, please. Just respect my vision for my story. Chara will be male. His age appears around Frisk's but he's spiritually older. Monsters tend to age slower than humans in this AU. This is a fanwork. If you think Sans x Frisk is cringy, I treat it as Beauty and the Beast so think of it in that mindset. Hope you guys enjoy this sad and fluffy story. I may or may not make this into a sketch comic one day? But this will have some of my sketch art here for big parts of the story.)
