Summary
Elysium is a place or condition of ideal happiness, a paradise reserved for the blessed. For Chara, you were that paradise. The one warm place in an otherwise numb existence. But Chara doesn't know how to love without consuming. Doesn't know how to want without possessing. Doesn't know how to hold onto something without digging their nails. Because in a world where Chara feels nothing—you became their everything.
You have spent your life chasing moments of warmth from the one person incapable of feeling anything at all. You have loved Chara since childhood, through every cruel word and mixed signal, through every moment of genuine warmth buried under years of manipulation and control. But... love isn't supposed to feel like this.
____
You dramatically hit your head and started recalling the memories of your past life. In the process, you come to find out that you were a plot device meant to die as the mastermind's childhood friend to a thriller/romance manga. Determined to stay alive, you decided to launch an elaborate scheme to save everyone: amuse them, surprise them, make your hollow-eyed childhood friend feel something beyond the quiet thrill of watching things die.

Summary
Remember the times you joked about "dying for your fictional crushes"?
Well, one chronically online, strawberry patterned pajama-clad Bad Sanses fangirl actually did—courtesy of a pixelated meme dog and what might be the universe's worst case of writer's block. Now, she's stuck in the Undertale multiverse with nothing but her AU knowledge, a deeply unserious System guide named Selene, and the terrifying realization that her beloved skeletons don't blush on first meeting.
They try to murder her.
Armed with terrible skeleton puns, niche references, and a soul that might be powered by sheer cringe, her new mission is clear: befriend the murderous skeletons, grind enough EXP to not die (again), and somehow stop the multiverse from collapsing-all while convincing a glitchy skeleton that she's not the weirdest thing he's seen today. (She is.)
It's a self-insert isekai where the only thing stronger than Determination is a fangirl's ability to ignore red flags.
[ I curse ao3 and its limited description. Uploaded this on Wattpad and Quotev as well! More active over there, this is my first released fic here :) It’s actually more serious than I made it to be lol! ]
