Doki Doki Literature Club Plus! (EU)

During acts 1 and 2, you will play a poetry mini-game at the end of every day. Your choice of words in this game determine what each girl (Sayori, Yuri, or Natsuki) says to you the next day. Once you reach a screen with half a notebook, some chibi figures, a few random words, and a counter that says 1/20 in the top right corner, you're in the right place. When this mini-game starts, rapidly tap the A button and you should finish the game rather quickly, popping the achievement.

Note: Keep in mind that the poems you write dictate how the story unfolds. If you're intent on pursuing a certain girl, or in my case, an achievement, save your game right as the minigame starts. I ended up delaying the minigame by about ten seconds doing this, and still managed to get the achievement. This way you can load the save, and then actually write the poem you want to write. Happy hunting!
