It's sometimes the best time of day.Bitching about work with friends/lover is so cathartic, I understand completely.
I did a few times when I was in university, and it generally happened after drinking about 5-6 shots in a relatively short amount of time, like maybe an hour or two, and I'm a 6 foot tall man. I think it's not implausble that a young woman of short stature could get blackout drunk in a pub fairly quickly. But it seems unlikely it'd happen after her second drink. Though east asians are supposedly more susceptible to alcohol than many other ethnicities.This is almost a non-sequitur but getting blackout drunk is pretty darn hard in my experience. Most of the time I roll my eyes when seeing it used as a plot point in manga. Here though it seems even more egregious since this is a more grounded story .
