The Circumstances of Becoming an Unwanted Protagonist

A friend asked me to beta test and give honest feedback on a reverse harem game.
But it turned out it wasn’t just an ordinary mobile game—it was VR?
I ended up becoming Sienna, the troublesome fiancée of my favorite character in the game, who’s just a background extra.
The problem is that every time an episode triggers, I’m forced to act according to the scripted plot.
The lines are cringy, the actions are childish, and every night, I’d kick my blankets in shame from the embarrassment, until I finally caused the major incident set by the scenario.
I thought I had finally gained my freedom after getting spectacularly dumped by my favorite character… …but did I write the feedback too honestly? Suddenly, I was updated into the game as the hidden heroine.
If I succeed in capturing the male lead’s heart, I can escape. If I fail, I lose “myself.”
Since it’s come to this, I decide to actively target the male lead to clear the game as quickly as possible and go back.
