Summary
En un Snowdin cubierto de nieve, Chara sigue sonriendo como si todavía supiera guiar a cualquiera hacia un final mejor.
Frisk, una presencia espectral tan seca como observadora, no tarda en notar que esa energía brillante es también una forma de no romperse.Lo que empieza como una ruta improvisada por el subsuelo pronto se convierte en otra cosa: una herida abierta, una verdad imposible de disimular y un vínculo que deja de parecerse a una casualidad. Mientras Mettaton carga con un plan que no piensa explicar y Asriel observa más de lo que dice, Chara y Frisk se ven obligados a enfrentar lo único que ninguno sabe recorrer bien: quedarse.
Una historia sobre rutas fallidas, manos que por fin se alcanzan y un fantasma que aprende a volverse real porque alguien decide no soltarlo.

Summary
In a snow-covered Snowdin, Chara keeps smiling as if she still knows how to guide anyone toward a better ending.
Frisk—a spectral presence as dry as he is observant—doesn’t take long to notice that all that brightness is also a way of keeping herself from breaking.What begins as an improvised route through the Underground soon becomes something else entirely: an open wound, a truth neither of them can hide, and a bond that stops feeling like chance. While Mettaton carries a plan he has no intention of explaining and Asriel sees more than he says, Chara and Frisk are forced to face the one thing neither of them knows how to navigate well: staying.
A story about failed routes, hands that finally reach each other, and a ghost who learns how to become real because someone chooses not to let go of him.

Summary
Twice did Seam hear about this strange door from their friends, a door that appeared in a hallway that wasn't always there. Only once did they see that door, and only once did they enter it.
That's how they met The Man.
Like a 5+1 thing but it's a 2+1 instead because that's all I could come up with.

Summary
Existe uma história que todo mundo conhece, uma que não precisa ser repetida. Mas o antigo misturou-se com o novo, dando à luz uma obra composta pelo imutável e por aquilo que mudou. Oito humanos caíram. O primeiro foi perdido, assim como seu irmão. Mas último não era mais o mesmo. E um dos outros seis era um pecador. A história que todo mundo conhece ainda existe, mas mudada. Transformada. Não é mais a mesma história, mas, ao mesmo tempo, é. Medos antigos e memórias ruins transformaram-se em agressividade e raiva. Certezas e fé transformaram-se em dúvidas e receio. Uma jornada difícil transformou-se numa jornada ainda mais difícil... mas muito mais recompensadora.
E com tantas coisas iguais misturando com coisas transformadas, eu não consigo não me questionar: o que mais vai se transformar? E o que se tornará?

Summary
"You never know." You shrugged and flopped down on the grass beside our oak tree. I lay down beside you, letting your arms drag me closer and wrap around my torso. Our chests rose and fell in tandem. Above us, the stars stretched far into the pure black sky. They seemed to be shining brighter than ever.

Summary
Why write something positive when you can write about your favorite ship when the other one is dead? I feel like this idea has been used many times before but I wanted to try it myself.
I wrote this to practice and I'll probably write a lot of one shots to improve my writing.
