<The Book Of John Part 2: 끝의 시작> 时隔10年发行的正规6辑《The Book Of John Part 2: 끝의 시작 (End of Innocence)》 收录了过去几年发行的单曲和新诞生的5首歌曲，一共10首歌曲。 JK김동욱亲自创作了10首歌曲的词和前奏，专辑主打歌《G I A N T》是通过与吉他手兼MV总监Jimmy Chang和被评价为新一代音响匠人的윤숙영二人合作而诞生的歌曲。 以Banff和Jasper一带自然的雄伟为背景拍摄的《G I A N T》MV中，将和我们经常在一起的自然这一巨大存在比喻为巨人，表现了人类生活中绝对不能没有的存在。 1. 가끔 (Wonder) Produced by JK KIM DONG UK Lyrics by JK KIM DONG UK Composed by JK KIM DONG UK Arranged by Mantra All instruments by Mantra 2.
