Alternate Universe Fan Fiction: Kuroo Tetsurou and OC (Muarasaki Yura)

Crimson Instinct
A Vampire Romance

"An immortal life means nothing... until someone teaches you to treasure a single day."

For over six hundred years, Professor Kuroo Tetsurou has lived in the shadows.

An Elder Vampire feared by monsters and respected by the ancient Vampire Council, he has witnessed kingdoms rise and fall, loved ones fade into history, and centuries pass without changing a single strand of his black hair.

Immortality has taught him one lesson:

Never become attached to humans.

They always leave.

Then he meets Murasaki Yura.

A brilliant, kind-hearted college student with an infectious laugh, an inexplicable love for stray cats, and blood unlike any other.

The legendary Crimson Blood.

Every vampire longs for a single taste.

Every rogue clan would start a war to possess her.

Yet Yura possesses a miracle hidden within her veins.

She is the only human in history who cannot be turned into a vampire.

No matter how many times she is bitten...

She will always remain human.

As Kuroo struggles between centuries of vampiric instinct and the growing desire to protect the woman whose scent calls to every predator, Yura unknowingly falls in love with both her mysterious professor...

...and the fluffy black cat named Mr. Whiskers who keeps stealing her pillow.

But some battles cannot be won with strength alone.

Because the greatest enemy an immortal can face...

...is time.

When forever belongs to one of them...

...and only borrowed days belong to the other...

Can love survive the difference?

Or will eternity become the cruelest curse of all?

A slow-burn supernatural romance filled with humor, longing, quiet moments, and unforgettable love, Crimson Instinct is a story about choosing kindness over instinct, today over forever, and the courage to love even when your time together can never be enough.
