Summary
"Somos desconocidos tú y yo,
¿qué nos hace diferentes de lo que alguna vez fuimos y nunca seremos?,
ya no somos los mismos, es un hecho,
¿entonces por qué el dolor sigue siendo el mismo?"★ ★ ★
Error ha pasado su vida tratando de olvidar a Ink, con quién alguna vez creyó tenerlo todo.
Ahora, casi a sus 30 años, está listo para cumplir una promesa con la que finalmente dejará atrás el pasado. Pero, el destino tiene otros planes y un reencuentro inesperado podría avivarlo o destruirlo todo.
No todo es lo que parece y un secreto guardado durante años podría reescribir su historia.
¿Podrá el amor que una vez los unió sanar las viejas heridas?
¿O seguirán pretendiendo ser desconocidos?

Summary
“Just one bite,” Dream coaxed softly. “Please? You can tell me if it’s awful.”
Nightmare hesitated, gaze lingering on the offered food as if it had personally insulted him. Then he sighed, long-suffering, dramatic.
"If I must," he said. "But if it’s bad, I will not spare your feelings." There was no teasing in his tone. Only sincerity. Absolute, devastating sincerity.

“Your usual?” I say glancing up at the tall skeleton, scribbling down his name on the cup
A blank gaze returned, “I’ve never been here?” A confused look on his face.
“Papyrus?” raising an eyebrow, was this a joke? that’s more of Sans’s thing
“Nope” The tall skeleton chirps back, a laidback look on his face, glancing at his outfit he was wearing khaki pants and an orange hoodie. Who is this? -

Summary
“Just for one day, Geno,” Sans says with a gentleness normally reserved for their brother as he holds his hand out. “I want to give you the chance to see more than this darkness, even if it’s just for a little bit.”
He shouldn’t. He really, truly shouldn’t, and yet he does. Hesitantly reaching his own hand out before placing it in Sans’ hold.
“… I’ll be in your care,” Geno quietly says, hiding his colored cheeks in his scarf.
Or, Sans takes Geno on a date 💙❤️
