Oh No, I'm Surrounded by Yanderes

You just wanted to play a dating sim, but you're now trapped in a system world with four yandere leads. Only by completing one romance route can you hope to return to reality. But the system didn't tell you that beyond these routes, a much more dangerous hidden ending lurks.

You are a beta tester for the high-freedom dating game Perfect Lover. Expecting a virtual romance, you enter the elite 'Chengchuan Academy,' only to find the exit button has vanished.

System Prompt: 【Current route incomplete. Exit unavailable.】

In this elite academy, you'll encounter an overly gentle school doctor, an arrogant and obsessive scion, and a student council president who seems to control everything behind a mask of propriety. They are infiltrating your life, forcing you into their order. In this game where you cannot log out, you must conquer one of them to earn your freedom. But be careful—the 'romance' may just be the trap that holds you captive.
