Dude, I am better. You cannot think straight because you are so damn triggered. So here are the facts one last time:
If we take the chapter at face value, she bought an alcoholic drink by accident, which they shared. BOTH of them are slightly intoxicated. I now realize that you are probably too fckin young to drink so u don't understand but one 0,5 Bottle of any kind of mix drink does NOT knock out a person. Repeat yourself a thousand times, it is not realistic in any way. Maybe you need to actually read 57.2 where he clearly isn't out of it before going to bed. People with actual experience can make a good guess at how much alc does what, fiction doesn't change that because this manga is a rooted in reality.
Furthermore there's no evidence that it was premeditated. For all we know she got tipsy and decided to night crawl - he responded, started sucking her tits. So she had no reason to believe that he doesn't want to, neither did he say so at any point. Even in the later chapters.
Now stop projecting. You are virtually screaming and crying in written fashion, yet I am the one hung up? No, I just won't let your BS stand. If you wanne fault me for something, it's that I argue with you despite knowing Mark Twains law.
