A yandere girl in manhwa is often extremely possessive and obsessive about the person she likes. She can go to extreme lengths to keep them close, sometimes even resorting to violence or manipulation.
In manhwa, yandere boys typically have a dual personality. They might seem normal on the surface but go to great lengths to keep the object of their affection close. Their actions can range from overly protective to outright violent when they feel threatened.
I'd recommend 'Twisted Love'. The yandere male lead's actions keep you on the edge of your seat. The plot has lots of twists and turns that make it stand out. The way the relationship develops is quite unique.
The yandere female villain can be characterized by her extreme possessiveness. In the DC context, she might be jealous of any other character who gets close to the OC. For example, if the OC is friends with Batman, she would try to sabotage that relationship. She could also have a volatile temper, going from sweet and loving towards the OC one moment to enraged and violent the next if she feels the OC is slipping away.
A female yandere in fanfiction is often extremely possessive. She has an intense and sometimes obsessive love for a particular character. For example, she might go to great lengths to keep the object of her affection away from other people, even using underhanded or unethical means.
In fanfiction, the dynamic between a female yandere and a female reader can be quite complex. A yandere character is often overly possessive. In this pairing, the yandere's possessiveness can create intense and often conflicting emotions. It can lead to situations where the reader character might be both attracted and frightened. This type of relationship can explore themes of obsession, love, and power dynamics.
They usually have a dual personality. On the surface, they may seem normal or even sweet, but once their 'yandere' side is triggered, they can become very aggressive and controlling. For example, in many fanfictions, a female yandere might act all cute and friendly at first, but when she senses a threat to her relationship, she'll show her true, menacing side.
