Monika can be referred to as a 'yandere' - a violently possessive individual driven by their passion for their love interest. Doing so will ultimately reset the in-game reality and revive the fallen girls. To punish Monika and alter the player's fate, Doki Doki has a hidden mechanic that allows the MC to delete Monika's character file on their computer. Monika claims the MC for herself and promises an eternity together against their will.
Sayori, Yuri and Natsuki all perish, leaving only Monika, the Literature Club President, along with the MC.
Subtle hints suggest that all is not as it seems, and in turn, each girl begins an alarming mental decline that yields 'deadly' results. The MC chooses their love interest and aims to impress them with flattery and poetry.
As a first-person romance, Doki Doki assigns the MC (main character) role to the player, who becomes the object of infatuation for four prospective dates.
