- The main cast's backstories, especially Takuru, Hinae, Nono, and Uki.
- Both of Uki's good endings. One has her be a vegetable and cared for by Takuru, and the other has her flat-out die. Takuru is also suffering hallucinations from her death, as seen in the CG where it shows her shadow standing in a doorway.
