infected ((yandere x reader))

I- uninfected

(Y/n) had sort of always known the world was fucked up.

The first instance of her knowing was when her uncle died. She didn't know him all that well and wasn't overly affected by it but when she asked her mother what happened one thought crossed (Y/n)'s head:

'That... Is very fucked up.'

Her mom told her he'd been murdered which shocked (Y/n) right off the bat, she said the murderer had been caught but was not given any jail time as it was deemed a dispute over love.

And that was the end of it.

More friends and family would crop up dead over the most trivial things... But everyone said it wasn't trivial- it was for 'love'. They told her that everyone should be willing to both kill and die for love.

What shocked the young girl even more was when she expressed how she felt to her parents she was dismissed for it. They told her she was too young and that the infection hadn't properly taken root yet and then when she was eighteen and got properly diagnosed she'd understand.

But even other kids found it normal.

Not (Y/n).

(Y/n) was the only person she knew who was against murder... An odd thing to be an unpopular opinion but oh well.

She learned to keep her reservations about society to herself, (Y/n) told herself that she would indeed get it one day and that day was today.

It was finally her eighteenth birthday and the excitement of the day was going down to the doctor's office to get her blood tested.

It couldn't be called tradition, it was more legally required. She'd be tested and then given identification for whatever strain she had.

There were four separate strains of infection and the one that someone had affected their personality and how they approached their love life which, in the society (Y/n) lived in, was the most valued thing of all.

Her blood would be taken and a specific indicator is used to change the colour of the blood. Depending on the antigens present the blood and turn one of four colors:

Around thirty-five percent of people's blood would turn a bright and sunny yellow in the presence of an indicator. This would signify the obsessive strain which (Y/n)'s father happened to fall under. An obsessive was, as the name suggests, totally enamoured with everything their beloved did.

A pale green would overtake the red coloring of the blood of a further thirty percent of the population. These people had been granted the possessive strain. (Y/n) had met a few possessives over her lifetime though had never met any of their lovers, she expected that anyone partnered with a possessive would hardly see the sun.

Twenty percent of the infected blood would turn a mellow greyish-blue, this meant they had the protective strain. (Y/n)'s mother had the protective strain and didn't she know it, the way she was around her, her brother and her father was evidence enough of it without any test needed.

The most rare strain only affected fifteen percent of people, their blood combined with the indicator turned a deep and regal purple. These were the sadistics. A sadistic would show their love through inflicting pain upon their beloved, it wasn't uncommon for members of society with the other strains to turn their nose up at sadistics in disgust, protectives especially held bad blood with them.

If a person was tested but the indicator did not detect any strain of infection then the blood would not remain red, instead it would turn to a pure white.
