If I were an ordinary character in an erotic game

Concept
You become an ordinary character in a hardcore erotic game.
Actually, you have no name or no image in the game.
One by one, men attack her with a twisted desire.
Being an unspectacular person, can you succeed in saving her?

You are not in the key person in the story.
If your choices are bad, the girl you love gets violated. And when your choices are good, the girl you love falls for the boy she loves.
Either way, you'll never get the girl.

Story
The main character is an ordinary school boy.
He has a secret feeling for his classmate, however, he thinks she is too perfect for him and he can't gather courage to declare his love.
One day, he realizes that there are several evil persons who have a perverted desire towards her.
And that some of them have already concrete plans to violate her.
For some reasons, he encounters her when she is in clutch situations.
Can he help her?
