Seeking Looking for a game where female MC's friend gets corrupted before the MC gets corrupted herself

[dave987654321]

Any suggestions?

 

[Pretentious Goblin]

Star Knightess Aura, with caveats: MC's childhood friend corrupts her, and also corrupts MC's friends. It's still early on though (20% to 1.0), and the corruption in the real-world so far is non-sexual (hobbies, clothing, etc.).
