I really disagree with this "cynical" talk of you two's. That is only true if we accept that sex is something bad/evil.

A stranger girl asks you to stay, she offers sex, it's a deal. And it's without proof to assume that it was always unpleasant sex, Sayu carefully picked and chose the guys, and the 2 we've seen so far were at least average to handsome, so this isn't some "ugly bastard raped her" scenario. It was never rape to begin with.

I feel like you guys are hung up on her being a school girl. Imagine if we were talking about some 25yo woman. Would you still condemn men that'd require sex with her as a way to pay for a stay? I don't think it's morally right to let a grown woman stay at your home for free, most people would find that odd. With Sayu, you have her teenage status, but she's not some helpless, innocent 10yo girl, she's an almost-adult who can legally have consenting sex. The men who chose to have sex with her (that SHE offered) aren't evil for doing so.If anything having sex made Sayu's situation more plausible to them, like "ahh, she's on the street and wants to earn money with sex. Okay, come on in". The alternative would be to let a prostitute stay at your place for ... for what? So she can leave and then have sex with the next guy? Thats where the unrealistic scenario comes into play again: If you were against having sex with her, you WOULD absolutely call the police to help her. Because how do you help a teenage prostitute by staying at your place, when you have to assume she's still going out to get banged for money?

It's sex. Not a crime. So don't judge those men. Sayu chose this.
