In real life, Junhyung is known as the song producer. He creates lyrics and always had a book or memo to write his inspiration.. which.. all of them poured into great songs. So I pick Junhyung as a high schooler that owns a diary. There will be two signs: [OFF DIARY] and [ON DIARY]. Some chapters can be short since I'm making Junhyung on diary to write what he experience in his daily life.
