The whole rape fantasy (push her down forcefully, have my way with her even with her protests, etc.) side of chapter 4 really bothered me until I realized that what the chapter did was reject the idea. When Maki is fantasizing, it's because that's what she knows of how it's supposed to be, as well as an indication of her reaching the breaking point. But when confronted with a vulnerable Nico with tears in her eyes she stops, realizing that's not what she wants at all. She wants a Nico who's a participant rather than a victim, and is supremely happy when she achieves that.
It's great when you see something that doesn't buy into the idea that sex has to be scary or awful for one party.
