"길라임 씨는 몇 살때부터 그렇게 예뻤나?"
길라임 (heroine's name)
씨 (the title of someone in politeness)
몇살 (how old)
때부터 (from when)
그렇게 (like that)
예뻤나 (basic form : 예쁘- / conjugation : 예쁘+어+ㅆ → 예뻤- (past tense)
예뻤+나(question) 예뻤나 (past tense question)
reminds me of the scene when they were doing sit ups :))))
Since when di you get so pretty? 길라임 :))
That's okay but "Since when did you become/get so pretty?" is more natural.
Since what age did you become so pretty? <- Is it also okay? 이것도 맞아요?^^
At what age did 길라임 씨 become beautiful? 몰라요 :)
