Chapter 5: The NOexistenceN of You, and Me

To unlock this ending, you’ll need to select the most negative responses throughout Chapters 1 to 4. (Note: You don’t need to choose all negative options. The “Favorability” must remain below the standard level. However, to ensure this achievement, it’s recommended to stick to negative responses as much as possible.)
- Chapter 0 (Prologue): Select the “I hate you” option, which should be one of the last lines of the chapter.
- Chapter 1: Choose the option that mentions Lilith being a murderer. Let Lilith lick the cake from the ground, and do not claim it was a joke. Continue further.
- Chapter 2: Select the option that says you hate Lilith’s name and erase it. During the RPG minigame, repeatedly express how bad and boring it is.
- Chapter 3: Either push Lilith off the Ferris wheel or refuse to trust her and tell her to jump first.
- Chapter 4: Do not believe Lilith’s medicine is real medicine. Keep insisting it’s just candy and ask for more or steal the jar.

You and I exist

- Choose the best answer for chapters 1-4
- Chapter 1 Comfort her when the cake falls to the ground, enjoy the process of making it rather than the result
- Chapter 2 praises Lilith’s story and encourages Lilith’s creativity
- Chapter 3: Lilith asks if you want to jump, jump without hesitation
- Chapter 4: Believe that candy is medicine. When Lilith says you can only eat three a day, don’t continue to ask for more. Choose to wait until tomorrow to eat.



You and I exist

- Chapter 0 (Prologue): Select the “I love you” option, which should be one of the final lines of the chapter.
- Chapter 1: After the cake falls, choose “…” (stay silent) and later select “It’s all my fault.” line.
- Chapter 2: After defeating The Demon Lord and speaking with Lilith, choose the line mentioning that the game is boring, followed by “It’s all my fault.” line.
- Chapter 3: Upon reaching the Ferris Wheel, choose “I feel like I’m not welcome by anyone.“
- Chapter 4: The choices here don’t have a significant impact, but it’s recommended to continue believing that Lilith’s candies are medicine. You can either choose to wait until tomorrow or attempt to take the jar/ask for more candies.
