First time use melon music to listen to Sik-K fly songs. Can only listen to 1 minute preview, in fact I can't buy tickets and watch his video just because it is difficult to verify the age of, moreover I was just 18 years old lol. I also can't buy cash and pay through kakao pay. I have to move to korea in order to do this all lmao . But i love the song, and purchase in other app lol.
