SAVEtale

SAVEtale is a Korean au made by Tarëcat.(me! I'm tarëcat)
the story starts when chara, feeling miserable because she fell into a monster pit, decides to reset. But she is stopped by Sans who killes her to save this timeline. Some while later asriel finds her body and decides to take her soul and escape the underground. He fails and the humans toss his body back into the underground. After that it's the same with undertale except the fact that the game glitched because chara died the moment she reset. Because of this, she falls into the underground again with her memories erased. She falls into a timeline where frisk died while fighting asriel and the monsters are still trapped in the underground. She meets the monsters but everyone just goes into shock when they see her face(because she looks like the late princess chara) sans especially because he still has the guilt of killing Chara.
In this au sans is mentally unstable(he loved frisk) and is afraid of losing someone he loves
he winces every time he sees ???(glitched chara) and seems to be relieved that they lost all their memories.
he wears a jacket similar in design with original Sans except the coloring.
everything in this au is colored a light navy.
He winces every time he sees ???(glitched chara) and tri
es to avoid them. He has tiny cracks in his soul because the death of frisk broke his heart. He can give his hp to others but doesn't have much of it.
???is glitched chara and has only bits and pieces of memories. She dislikes sans but doesn't know why. She wears a dark faded navy colored cloak with a savepoint. 
Chara is a psychopath who weilds a double basterd sword instead of a knife
