Yan!Nightmare x Reader (DISCONTINUED)

A/N

types of yanderes that the bad guys are:

Nightmare:
-the wrong idea type:

"They gave me an eraser... this must mean they love me!"

They get the wrong idea when something is done in order to match their expectations. If you say you don't love them, they'll think you're lying because you don't want to hurt them. If you do something out of kindness to them, they'll think it's out of love.
-

stalker type:

"Although you don't know it, I'll always be with you!"

Will follow a their interest around, often without them knowing. May be in broad daylight or at night, when they're walking alone on the streets, or even online if relevant. A person of this type is also often of the obsessive type.
-

monopoly type:

"Who is that person you were talking to?"

They want to monopolize their love interest. And will ask who they're talking to and hanging with, in extreme cases won't let them be with anyone else, regardless if they are well known as a mutual friend.

This type of behavior is unfortunately common in real life. It displays insecurities and lack of trust in the relationship which might develop into much worse yandere behavior.
-final type:

"I don't need a world where they don't exist."

After learning their love died, they lose their purpose in life. The world for them was their love, and they're now gone. What this results vary. Most of the time, they become broken emotionally, as expected. They might also commit suicide. Or sometimes, they might become a terrorist and destroy the world that let them die, or just go on revenge serial killing.
-worship type:

"I'll do anything for you! I'll even kill for you! Please use me however you want!"

They worships you and will do anything for you. Sometimes even without you asking. And more: They don't even mind if you love them or not, or what will happen to them. Killing, dying, committing crimes, losing respect of others, they'll do anything it means providing support to your infinite greatness.

This is one of the least-harmful type of yandere to one self since they would never do anything to harm you and will never be in your way. Nonetheless, it's also one of the most depressing types; it makes you feel sorry for the yandere, who thinks of themself less like a person and more like a tool who might get thrown away if they're not useful enough.

The difference between the "worship" type and the "self-sacrifice" type is that the "worship" type is also like the "disappearance" type. The "self-sacrifice" type wants to be useful so they can be loved, the "worship" type doesn't mind if they are not loved back, in fact, they probably thinks they are not worth being loved by the delusive greatness they consider you.

They wouldn't, for example, attack your partner or other people out of jealousy, but they might attack a person approaching you because they thinks this person is stepping out of their boundaries and being presumptuous by daring to talk to your greatness without proper respect.

Error:
-removal type:

"You don't need other people. You have me."
