This is a modified version of Windows 8.1 Embedded Industry Pro. I call it "Windows 9"
It was designed to bring back the UI from Windows 7, while keeping the kernel improvements from 8.1
You need a license key to activate this operating system.
If you are in college, check if you have a Microsoft Imagine subscription. You can usually get an 8.1 Embedded Industry Pro license key from Microsoft Imagine for free.
Windows 9 is x64 only - this will not work on 32 bit systems.
If affected by a black screen issue after windows update, please visit this page for instructions on how to repair.

The prologue sets your personality. For 100% completion, you want a "Balanced" profile (so you can pivot between Melody and Becca).
Don't just skip dialogue. The music in this game was overhauled in the V1.00 patch. Listening to the "live tracks" added between weeks 1-12 enhances the immersion significantly.
In Level 3, the rhythm slows down, but the note combinations become more complex. Take your time to adjust to the new rhythm and note patterns. Choose the "Analyze" option before acting to unlock
Whether you are playing the English original or the Chinese “Extras” version, use this walkthrough and the in‑game purple‑highlighted choices to maximize your Melody points. Manage your character routes carefully in the main menu, especially before the final week, and you will unlock every scene and ending the game has to offer.
If you are on Melody’s route but kept Becca’s friendship above 50, you will receive a voicemail. Do not delete it. Listening to it fully unlocks a hidden “Jealousy” variant in the Day 25 confrontation scene.
