To write a good Sans x OC fanfiction, start with a strong concept. Think about how your OC will fit into the Undertale universe. For the relationship with Sans, build it gradually. Don't rush into a romantic relationship right away. Show their friendship first. Add some conflict, like an enemy that threatens both of them. And don't forget to add some Undertale - specific elements, like the different areas in the Underground and the other characters. This will make the fanfiction feel more authentic.
First, develop your OC well. Give them a unique personality, backstory, and appearance. For example, if your OC is shy, explain why. Second, understand Sans' character from the original Undertale. His laid - back yet observant nature should be reflected in the interactions. Third, create an interesting plot. Maybe your OC has a special power that affects the Undertale world in a new way. Also, use good grammar and spelling to make it a pleasant read.
