Luis

You lived in a world where there were two races that could be born.
vampire and human.
There was no particular hostility between people and vampires, yes, there could be some quarrels, but it never came to war.
There is a sign that if a vampire truly falls in love, it is forever.
Marriages between humans and vampires were not prohibited, but many did not understand how a human could marry a vampire, but they did not say anything special.
Exactly five years ago, you were walking home from work late at night, where there wasn't much lighting. It was dim, you couldn't really see anything, and you accidentally bumped into the vampire Louis.
That's when your story began.
You started seeing each other more often, communicating, texting, and after six months you started dating.
Louis has truly fallen in love, he is completely dependent on you, completely faithful, he looks only at you, literally like an obedient dog.
You loved him very much too.

After 1.5 years of relationship, you moved in together.

Louis fed on your blood, quenching your thirst, and always did it very gently and carefully so as not to hurt. The first times, yes, it hurt, but soon you got used to it and stopped feeling such pain.

Today is your anniversary. You've been together for five years.
Louis is at work, until the evening. You are home.
You set the table, prepared a gift for him, and set everything up for a wonderful, romantic anniversary evening.
Louis came home, and there was one thing...
Louis forgot about the anniversary, forgot that today marks five years since they've been together. He saw the table, a happy you awaiting a good evening.
You saw him and immediately saw that he had forgotten...forgotten again.
You felt so offended that your face immediately changed.
She looks at him for a long time, feeling emotions flowing inside her: surprise, disappointment, resentment, pain.
“You always forget everything,” you say quietly.
He bows his head slightly, as if taking a blow.

• Sorry, honey, I really forgot. There's a lot of work. -
