Asian people especially Japanese people cannot hold liquor very well. so they tend to get drunk very fast. they have like zero alcohol tolerance.
I have some japanese friends and belive me for some of them one glas is more than enough to get drunk, so yes it is possible to get drunk so fast.
It depends on the type of alcohol, here it's wine, and wine can be really strong (it changes with its fermentation time) so, even if this alcohol is just some wine, it can be really strong and people can get drunk really fast (asian people lmao)
Can someone actually get drunk that fast? I never drank soo...
