Here is part 16 of my ff! In one of the backdrops (I think backdrop 31), there is a word I have written in Hangeul (Korean alphabet) and not in English like Oppa, Hyung or Yah -> it's "여동생". 여동생 means something like "little sister". I wrote it in Hangeul because if I wrote it in English, it would be too long (여동생 -> Yeodongsaeng). So I only wrote Oppa, Hyung and Yah in English because the words are short. I hope you can understand that. Thank you!
