@Mafeb the sentence meant that "even when you are able to drink, you can just drink it in moderation so that there's no issue" so using "can't" would be wrong in that sentence i think cause it would mean that he will allow a bit of drinking even if its not fine.
will fix the liqueur(need to fix the spelling lol) and liquor switch if i find it >side note: liquor and liqueur are different (liqueur is liquor flavored with various ingredients and usually much sweeter)
tnx for the correction~
Side Note: do correct me if I'm wrong about it ... cause i'm no genius
Edit: will upload the fix after mangadex gets over its hiccups
