You are sitting relaxing near the house while watch kdrama, suddenly, there is a delivery guy

hi this is your package

You're strange because you didn't order anything. Then, you went in and opened the parcel

After you opened the package, you were shocked!! because you got a limited edition novel that you have been wanting for a long time

I want but can't get it which is Prince Of Death. You are happy but in that time you're weird. Who gave it to you?

You're too lazy to think who gave this book, don't be rejected. When you rummaged through the book, there was a small note tucked in

𝙸 𝚑𝚘𝚙𝚎 𝚢𝚘𝚞 𝚎𝚗𝚓𝚘𝚢 𝚝𝚑𝚒𝚜 𝚋𝚘𝚘𝚔 "𝚏𝚛𝚘𝚖: 𝕮𝖆𝖑𝖊𝖇 𝖊𝖛𝖊𝖓𝖉𝖊𝖗"

you are getting weird, who send you this limited novel?
