'MC' isn't a hero, he's not even the main character. He's the player character that allows you to interact with the main characters.
That said, he is also just a normal guy who owns a hotel. His only super power is being supportive and being the glue that keeps people together (does a big cock count?). Things the player could do in real life if they wanted to, unlike many of the things the main characters do.
But I understand you want the player character to be more active, he's certainly not afraid though. This is a process and can't begin immediately. The moment where you had the option to shake Nia's hand in Maria's story is a good example of MC having the option to take things more seriously. We are moving out of that transitional period for many of the main characters, where they go from dealing with more personal problems to more wide spread problems. This will in turn cause the player character to act with the main characters. But I also wanted to make a point to show that the player character isn't a super hero that looks at the world and believes he can save it alone. He will be a better leader in the future, that is certain.
