Desire // Yandere!Reader x Underfell!Sans

It won't be implied if the reader is a monster or a human or whatever in between, so you can imagine whatever he/she/it/they look like. This is pretty much gory stuff and all that, so...uh, yeah. If you're not into that.

Remember, a yandere character does not feel emotions for other people, and normally fakes emotions (take fresh sans for example--he is not yandere (or at least, many versions of him are not) but he needs to fake emotions to blend in with his prey (I also feel like his species--specifically a parasite could communicate with other means), with other people he might eventually need to host). This means that if the reader ends up befriending anyone other than the one that they want for themselves--then many, if not all of the emotions they display are fake towards that friend. Yandere characters disregard the safety of other people and themselves, so they don't care if other people get hurt or murdered in the process, hell, they do not care if they themselves get injured. They only care about their lover. Yandere characters lie, steal and fight often, so if this story ever continues, there will be conflict. Yandere characters do not show guilt or remorse for their actions, only if their actions have consequences such as their lover hating them or their lover being killed. Yandere characters are more than not angry or arrogant, so this may proceed with the reader seeming more hotheaded than you might actually be.

This story might be continued or it may not, I don't know yet. Further chapters may be longer or shorter, though my plans are for chapters to be longer. Comment recommendations, advice, tips, anything you think would help. It'd be nice for people to make assumptions on what may happen next. Who knows, I might use that as inspiration!
