This is my personal interpretation of the events of Undertale as told from Chara's perspective. Obviously, this fanfic assumes that Narra!Chara is true.

If these changes bother you, consider this an AU.

Eran las primeras vacaciones que se tomaba. Sans pensó que serian relativamente tranquilas, claro, si se ignoraba los gritos de su hermano, Papyrus, y el enamoramiento de este con Frisk; la molesta y deportista Undyne, intentando que se levantase del sofá y moviese el esqueleto; además de la familia Dreemurr, conocia a Toriel, pero sus hijos eran otra cosa.
