Appetite - Substitute Girlfriend ~I'll Become a Slutty Gal to Protect My Best Friend!~ Final + Patch only (eng) - Adult Sex Game

I received a shocking confession from my best friend, Sumi Mizuki, that she had gotten a ***friend.
And to top it off, her partner was none other than the popular and handsome Matsui Tatsumi at our school.
At first, I was celebrating Sui-chan's relationship, as she was my only friend at school.
However, I gradually began to sense that her appearance and behavior were changing for the worse.
