For the full experience (priority access, reserved slots, and reduced rule-breakers), you may need to apply for whitelisting. Join the official Hillside Discord or community group. This process involves reading rules, filling out an application, and sometimes an interview.

There are other apps with similar names that you should not confuse with the visual novel: Hillside Drive

Because Hillside is not available on the official Google Play Store (due to its adult content), you must download the APK from a trusted third-party source. Always be careful: scan files with an antivirus before installing.
