Ayumi-kun "sowed the wind". By the end, he's about to "reap the whirlwind". Here's hoping (for his sake) he can handle Nozomi-chan, when she goes all out.
Relax and Chat? I'm pretty sure the only thing that happens in Hentai when it comes to alcohol is sex, sex, and more sex.
And also an ending like this where she comes to like it.
Still, this one was quite nice.
