Design risks

| R2 | Monetization | 0.00 | |
| R3 | Social risk | 0.00 | |
The game contains mature themes including violence, sexual content, and elements of fear/horror due to its 'serial killer case' and 'yandere' characters. While it lacks manipulative monetization or social risks, the intense narrative and mature content may be unsuitable for younger audiences. The focus on romantic relationships with potentially obsessive characters could also present complex emotional themes.
