In some yandere cheater x reader stories, the reader might initially be unaware of the yandere's cheating ways. For example, the yandere could be very charming and deceive the reader into believing they are single. But as the story progresses, the reader discovers the truth and has to deal with the yandere's overbearing and sometimes dangerous behavior.
In other cases, the yandere might reform their ways. After some events that make them see the error of their cheating ways, they might try to be faithful to the reader. This could involve a lot of groveling and promises to change. However, the reader may or may not believe them, and the relationship remains on shaky ground.
In yandere x reader fanfics, yanderes usually display intense emotions. Their love for the reader is not the normal kind; it's more of an obsessive love. They may have a dual personality where they can be extremely sweet and loving one moment, but if they feel threatened in their relationship with the reader, they can turn very dangerous and menacing.

In Yandere Sebastian x Reader fanfiction, the setting can also play an important role. If it's set in the world of Black Butler, the Victorian era adds an extra layer of elegance and mystery. The power dynamic between Sebastian, a powerful demon, and the reader, a presumably normal human, is a key aspect. The yandere Sebastian might use his power to manipulate situations to his advantage when it comes to the reader, all in the name of his 'love' for them.
