Monika is a cheerful, popular and enthusiastic girl, having all the qualities of a leader, while always maintaining a rather caring and motherly attitude. However, in the game Doki Doki Literature Club, this side of her begins to fade only to reveal a sort of "obsession" towards the player, forcing him to live with eternally in a room while looking at each other's eyes.
