It felt much longer than 2 years considering all the events that have happened so far in the story.
lol. bro is a drinker. he finished a whole bottle of sparkling sake by himself and is saying "better not over do it" lol.
Tbf, the bottle is about half-full. If that was a sparkling wine bottle (presumably very similar volume/bottle) it would be about 750 ml if it was full, so he had around less than ~400 ml, about 3 glasses or so.
At ~10-12% abv or so, that's about the right amount to get a good buzz (for me at least).
