Hello, I'm native Korean living in Seoul, I searched and found 핫뮤직(HOT MUSIC) 1993년 10월호 printed second hand books and I can send those to your address.
I found 핫뮤직(HOT MUSIC) 1992년 04월호 on online 2nd hand seller but the seller didn't answer my calls so I don't know I if the person would sell the book. and I doubt I can find GMV and 핫뮤직(HOT MUSIC) 1996년 02월호.
I just wanted to help you and I hope you can find someone who can find all of these books
