Well i did get around a whole month mostly by myself last time and im doing the same this time, and the base might be anime but the same is true for my english which is my 2nd language being cuban and i studied and work in the us in english mostly. And also studied the japanese language even if 2 semesters is not that much.
And the time in japan is no measure by itself. Ive seen youtubers that have lived 10+ years there and honestly suck at japanese imo.
And for the kure it is just an informal kudasai, as i said in my last post i thought he wanted the phrase to snuggle with a gf not a provider and kudasai seems cold or distant when talking with someone you are dating, i think. And there are way worse words like sore wo shiro(do that) or just plain order like kocchi koi (come here) which do sound more demanding/commanding but could be playful depending on your tone.
Lastly i have no idea about the quote cause i dont smoke as well, but im guessing they are japanese and they use the word kure right, so ill keep my tone and demeanor nice and think about when to say stuff like kure.
