Love For Negativity [Nightmare! Sans x Female Reader]

Prologue

There has been something that bothering my mind.
It wasn't such a big deal then, why now?

I sat on my throne, surrounded by the statues of various beings bowing to me.
I had learned something new, something that I didn't knew even in my formerly Guardian of Negativity time.
Love.
But not the family kind, but romance. I've come to know that before family comes romanticism.
I never acknowledge positivity emotion much, but now I am rather curious.
I wasn't the type to watch my surroundings and I was careless, but yesterday I was roaming the multiverse, taking my time and watching the lives surrounding me.
My eye spotted something, a young couple.
I was confused, someone married at such age? Then I found out I was wrong, I found out what it really was.

That was when I started to acknowledge and learn this thing that I was not familiar with.
For centuries and from the day I was born, I didn't knew this existed?!

Love, I had learned that it's one of the many kinds of Positivity. It gave happiness, joy, and comfort. But what I had also learned was that love is also in-between positivity and negativity.

Yes, there's a bad kind of love. It came from such things as manipulation and unhealthy obsession.
Love, it was the center of pleasures. Hugging, cuddling, kissing and sex, it all came from love.
I felt like a toddler who had just learned a new thing.

I had many womans whose I used as slaves, though I never felt even an ounce of attachment.
Now I was curious.

How I was curious for love.

[A/N]

I can't believe I'm doing a romance story.
Uh, I don't really know how romance ACTUALLY work so expect imperfection, but I'll try to improve as time pass on.
This is so unoriginal erghhhm...
Also, I'll change some of the characters personality.
Until then, au revoir!
